  • The Place of the Motivation of Search Activity in the General Hierarchy of
           Motivations
    • Authors: Vadim S. Rotenberg
      Pages: 1 - 3
      Abstract: The topic of this short article is a proposition that there is a special motivation of the process of search activity that belongs to highly developed animals and humans and determines not only the adaptation to the complicated environment but also the alteration of the environment by itself and the development of the subject’s opportunities. This motivation of the process of search has no special place in the hierarchy of motivations because it accompanies all motivations from the basic biological one up to the highest that characterize only humans. This motivation cannot be totally satisfied exactly because it stimulates process, not a goal achievement.

  • Deep Brain Stimulation in Parkinson’s Disease: Overview and
           Complications
    • Authors: Inês Ludovico; Alena Damborská
      Pages: 4 - 11
      Abstract: Deep brain stimulation (DBS) of basal ganglia has become a frequently performed surgery in patients with advanced Parkinson’s disease. Throughout the years, this technique has reached advances in imaging techniques, neurophysiological recording possibilities, and in hardware and software technology. Nevertheless, to reach optimal results of DBS therapy, a number of aspects must be carefully considered. In current paper, overview of DBS procedure is provided with special focus on complications of this, an even so ever more promising therapeutic approach.

  • Clinical and Psychological Factors Related with Tobacco Use Among Children
    • Authors: Arun Kuruppath; Pankaj Sureka
      Pages: 12 - 18
      Abstract: A purpose of this research was to study in school-going children (1) prevalence and pattern of tobacco use and (2) identification of risk and protective factor associated with tobacco use. In this 12-month cross-sectional school-based study, 1560 school children were included. Results indicate that majority of participants were urban Hindu male belonging to lower socio-economic status (LSES) who had positive family history of tobacco use among family members. Males and those with positive family history were more likely to use tobacco. Smoking was more prevalent in tobacco users belonging to LSES or having positive family history of tobacco use. In this study, smokers as compared to only smokeless tobacco users were older with longer duration of education. Majority of smokeless tobacco users paid from their pocket money while smokers needed to borrow from their friends. Smokers were more aware about the possibility of getting addicted to tobacco. Being of male sex and positive family history are risk factors for tobacco use in general and smoking in particular. Tobacco use in children is mostly financed by borrowing money from friends and pocket money with majority having made at least one to two attempts of quitting tobacco use. Effort needs to be made to increase enrollment of young tobacco users in tobacco-quitting programs.

  • Donepezil for Constipation in Lewy Body Diseases: Four Case Studies
    • Authors: Charles M. Lepkowsky
      Pages: 19 - 27
      Abstract: In Neurocognitive Disorder with Lewy Body (NCDLB) and Parkinson’s Disease (PD), constipation is an almost universal symptom creating hardship for patients and caregivers. Based on a literature review linking constipation in NCDLB and PD to Lewy Body cholinergic impairment of the enteric nervous system (ENS), it is postulated that the use of the cholinergic agonist Donepezil mightreduce the symptom of constipation. This hypothesis is tested through observation of four patients with NCDLB and PD at different stages of disease progression. When treated with Donepezil, all four patients showed marked reductions in constipation without exacerbation of other symptoms. It is concluded that the use of Donepezil appears to reduce the symptom of constipation in patients at different stages of NCDLB and PD, which might significantly improve the quality of life for patients with these disorders.

      Abstract: It is suggested that brain-derived neurotrophic factor (BDNF) has a protective role against brain lesion after an ischemic stroke (IS); however, there is inadequate information as to the role of BDNF in cognitive impairments following IS. This study evaluate the effects of IS and BDNF (Val66Met) gene polymorphism on global and multi-domain (attention, memory, verbal fluency, language, and visuospatial abilities) cognitive functions. In a case-control study, we selected 206 patients with IS who were consecutively discharged from Poursina Hospital in the north of Iran. The patients were compared with the control group comprised of 200 individuals who were referred to the Social Service Retirees Center in Rasht City. The comparison was made in terms of genetic variant BDNF Val66Met and also their scores in the Addenbrooke’s Cognitive Examination-Third Edition (ACE-III). The patients compared with the control group were suffering from higher rates of global cognitive impairment. [F (1398) = 38.29, ή 2 = 0.09, P < 0.0001] and lower scores in domains of memory [F (1383) = 39.57, ή 2 = 0.094, P < 0.0001], language abilities [F (1383) = 27.05, ή 2 = 0.066, P < 0.0001], and visuospatial functions [F (1.383) = 9.54, ή 2 = 0.024, P = 0.002]. In addition, carriers of at least one Val allele were suffering from greater rates of global cognitive impairment than Met/Met homozygous [F (1398) = 12.41, ή 2 = 0.03, P < 0.0001], and their scores in the domains of attention [F (1383) = 13.43, ή 2 = 0.034, P < 0.0001] and language abilities were found to be lower than that of the control group [F (1383) = 11.73, ή 2 = 0.03, P = 0.001]. However, the interactive effects of BDNF Val66Met × groups were not statistically significant (P > 0.05). The impairments are especially evident in domains of memory, language abilities, and visuospatial functions. Furthermore, there exists a relationship between the presence of at least one BDNF Val allele and impairment in the global cognitive functions, attention, and language domains. Nonetheless, BDNF Val66Met polymorphism does not seem to have a role in any specific cognitive impairment in IS patients.

  • Dream Characters’ Types of Involvement and Range of Relational
           Capacities in Non-lucid Problem-Solving Dreams (Part 1)
    • Authors: Miloslava Kozmová
      Abstract: Dream characters are present in dreams as the pervasive feature of dreaming consciousness. The current research was guided by the question, “What could be the types of dream characters’ involvement and range of their relational capacities in non-lucid problem-solving dreams'” In this study, 979 cross-cultural operationally defined problem-solving dreams were analyzed by the method of grounded theory for the dream characters’ participation and input into solutions and their relational skills, capacities, and abilities. The analysis yielded 56 exemplary dreams ranging from dreamers’ longing for characters and recalling helpful character, to their involvement in family dynamics, characters’ experiences of problems, joint problematic experiences, and characters’ helpful use of capacities and instigation of problems for the dreamer. Discussion revolves about dream characters’ absence and recalled presence. In the subsequent article, the author will present additional results, conclude the discussion, and include limitations of study and suggestions for future research.

  • Event-Related Potentials as Biomarkers of Mild Traumatic Brain Injury
    • Authors: João Gomes; Alena Damborská
      Abstract: Mild traumatic brain injury (mTBI) may lead to a wide variety of brain function alterations and is nowadays one of the least understood issues within neuroscience and sports medicine communities. Investigation and characterization of these functional abnormities are key to a better understanding of such changes. In current paper, a review of event-related potential (ERP) changes after mTBI is provided with the aim to critically evaluate this electrophysiological technique as a possible future diagnostic tool for impairments following the mTBI.

  • Review of Varieties of Dream Characters’ Presence in Non-lucid
           Dreams
    • Authors: Miloslava Kozmová
      Abstract: Besides dream selves—the experiencing individual dreamers—non-lucid dreams are often populated by characters. Because it is not yet known what could be the dream characters’ involvement and range of capacities in non-lucid problem-solving dreams, this paper focuses, in the preparation for the second part of this article, on the applicable literature about characters’ presence in non-lucid dreams. The aim of the present paper is thus to briefly review the variety of forms in which dream characters appear; the uncontrollable occurrences they are exposed to; the activities, abilities, or skills they demonstrate; and their ways of involvement with dreamers’ selves.

  • Four-Dimensional Consciousness
    • Authors: Richard Sieb
      Abstract: Conscious experience is the direct observation of conscious events. In the brain, it is structured as four-dimensional and these conscious events are linked (associated) by spacetime intervals. This may explain why conscious experience appears to us the way it does. Conscious experience is an orientation in space and time, an understanding of the position of the observer in space and time. Causality, past-future relations, learning, memory, cognitive processing, and goal-directed actions all evolve from four-dimensional conscious experience. A neural correlate of four-dimensional conscious experience is found in the human brain and modeled by Einstein’s special theory of relativity. The relativistic concept of spacetime interval might be central for understanding conscious experience and cognition.

  • Disruption of Neurosynaptic Physiology and Neuron Network Dysfunction in
           Brain Disorders: an Environmental and Occupational Health Perspective
    • Authors: Abhay Kumar Pandey
      Abstract: Signaling molecules are subject to impact of numerous products of risk genes and varied environmental insults. Networks of signaling cascades regulate new synaptic transmission and morphology. Pollutants may impact brain through cellular, molecular, and inflammatory pathways, causing direct damage or predisposing to damage by other insults, leading to diseases. Disruptions in structure and function of neurotransmission elements and protein networks contribute to pathogenesis of neuropsychiatric diseases. Different affected brain regions and/or synaptic connections between excitatory and inhibitory neurons characterize different specific clinical states. Identification of the functioning of synaptic signaling networks and specific neuronal pathways would facilitate identification of specific pathomechanisms with implications for preventive and corrective interventions. The present article attempts to garner greater emphasis in contemporary medical teaching, awareness, and preparedness for meeting the mounting health care challenge of pollution-inflicted disruption of neurophysiology and associated brain dysfunction and diseases.

  • Emotional and Interoceptive Awareness and Its Relationship to Restriction
           in Young Women with Eating Disorders and Healthy Controls: a Cascade from
           Emotional to Behavioral Dysregulation
    • Authors: Terezia Bernatova; Miroslav Svetlak
      Abstract: Recent findings converge to the idea that the central function of eating disorders (ED) can be understood as an attempt to control unwanted or dysregulated emotions. The restriction of food intake can be seen as the predominant and general dysregulated behavior with the aim to reduce emotional experience in women with ED. The aim of the present study was to test the hypothesis that emotional and interoceptive awareness as indexed by the Level of Emotional Awareness Scale (LEAS) and Body Perception Questionnaire (BPQ) will be in negative correlation with food restriction (Restriction Scale) and emotional eating (General Food Craving Questionnaire Trait). Our study was performed on women with ED (N = 73) and healthy controls (N = 207). The findings revealed that, in comparison with the controls, girls from the ED group were less able to discriminate their emotional states and were less aware of their body processes and autonomic nervous system reactivity. Contrary to our hypothesis, a three-stage hierarchical multiple regression analysis showed a significant effect of interoceptive sensitivity and emotional awareness on the restriction. Emotional and interoceptive awareness in women with ED explains the 25.2% variance of restriction in comparison with 8.8% in controls. It seems that the predominant use of restriction in the ED group could be explained by a limited repertoire of emotion regulation strategies or the persistent use of one emotion regulation strategy, such as restriction, while the controls had more options how to regulate their affect. Further studies are needed to explore the relations between these variables and the underlying causal mechanisms.

  • The “Hidden Observer” as the Cognitive Unconscious During
           Hypnosis
    • Authors: Noemi Császár; Felix Scholkmann; Gabor Kapócs; Istvan Bókkon
      Pages: 51 - 61
      Abstract: The question of how to define and explain hypnosis is still not completely answered. Most of the theories of hypnosis are based on describing it as an altered state of consciousness; others focus on intrapersonal and interpersonal aspects, sociopsychological, neurocognitive or sociocognitive processes. More detailed explanation of hypnosis requires a synthesis of these various perspectives — a task for future research. Recent experiments are in agreement with Braid’s concept of hypnosis (published already in 1843) defining hypnosis as a process enhancing or depressing neural activity as well as changing functional connectivity among brain regions; the brain regions involved in mental imagery are thought to be central for hypnosis. In the present article we suggest that the “hidden observer” under hypnosis might be due to the cognitive unconscious and that this special state emerges principally in highly susceptible subjects. Explicitly, the “hidden observer” might be nothing other than the cognitive unconscious.

  • Mechanisms of Stress in Humans
    • Authors: Christina Shih
      Pages: 62 - 70
      Abstract: The purpose of this literature review is to summarize stress-related research to better understand the mechanisms of stress. The connections between stress and environmental, physiological, as well as neurological factors were examined. Research has shown that stress exposure was related to cognitive dysfunctions, altered attention strategies, reduced capacity to experience pleasure, and higher risktaking tendency in achieving gains. A high level of stress was associated with greater hippocampal volume loss and was found to hinder memory retrieval while enhancing memory consolidation process. Physiologically, high stress levels were linked to shortened telomeres, elevated levels of circulating inflammatory markers, as well as hypoactivation of electrodermal activity and diurnal cortisol in response to stressors. Moreover, prenatal stress exposure was found to be a risk factor that can make an individual vulnerable to develop later stress-related physical and psychological problems. Researchers have also identified protective factors that can buffer individuals from the negative impact of stress.

  • Gamma Coherences in the Default Mode Resting State as a Measure of
           Consciousness Level
    • Authors: Peter Jombik; Michal Drobny; Beata Saniova; Martin Fischer; Petra Kaderjakova
      Pages: 71 - 77
      Abstract: Recent findings indicate that the default mode resting state network (DMRSN) is closely associated with conscious awareness. Thus changes in consciousness level could be reflected in turn in the DMRSN functional state. One of the most important requirements for proper network function is connectivity within the network structural constituents. One of the measures of functional connectivity is analysis of the EEG coherences. In this study we have examined changes in the mean coherences in the gamma spectral band 30–45 Hz in the DMRSN during general anaesthesia (GA) in the open thorax surgery were investigated in twenty patients. They were compared with physiologic EEG findings in twenty alert subjects and the mathematical model of brain death. Results of this study indicate that the decrease in coherences in the physiologic EEG and the patients with one lung ventilation (OLV) groups was roughly proportional to the increasing distance between the electrodes. This created some kind of a structure in the DMRSN. In the OLV group the main finding was a decrease in the coherences in the gamma band. Ten of the anaesthetized subjects showed a clear burst suppression pattern. During this condition the coherences in the pairs connecting the posterior parts of the network decreased. Moreover, the differences between the connections of the anterior to posterior parts of the DMRSN and connections between the posterior parts of the DMRSN were almost lost. However, they showed still highly significant differences in all items when compared with the mathematical model of brain death. In summary the results suggest that the functional connectivity in the DMRSN assessed by mean coherences could be a reliable method for assessing the depth of GA and may be useful for understanding disorders of consciousness in general.

  • Synesthetic Associations and Psychopathological Symptoms: Preliminary
           Evidence in Young Women
    • Authors: Marcel Neckar; Petr Bob
      Pages: 78 - 83
      Abstract: Synesthesia is a neuropsychological condition in which stimulation of one sensory modality or cognitive pathway is associated with unusual experiences in a different unstimulated modality. In this context a purpose of this study is to find relationships between word-color associations and psychopathological symptoms of anxiety (SAS), depression (BDI-II), alexithymia (TAS-20) and symptoms of traumatic stress (TSC-40) in 43 healthy young women (mean age 18.25). Results of this study show that colors associated to specific words have significant correlations with symptoms of anxiety, depression, alexithymia and symptoms of traumatic stress. Sum of scores related to color associations to these words create subscales that are significantly correlated with BDI-II (Spearman R= −0.60), SAS (−0.44), TAS-20 (−0.70) and TSC-40 (−0.64); p<0.01. The results indicate specific synesthetic-like mechanisms in association processes specifically linked to psychopathological thinking, feelings and imagination.

  • Communication Without Consciousness: The Theory of Brain-Sign
    • Authors: Philip Clapson
      Pages: 84 - 107
      Abstract: Despite developments in neuroscience, consciousness is unidentified in the brain. Moreover there is no scientific definition of what it is or does. This paper proposes that consciousness is not a scientific category. However, by ‘postulating’ consciousness as self-explanation, the brain can communicate with other brains in collective action. But the brain can generate a more plausible self-description as brainsign. There are two foundational tenets. (1) Brain-sign arises from the brain’s interpretation of its causal orientation towards the world at each moment, and is ‘apparent’ as the world; and (2) It facilitates communication between brains about the world in collective action which is uncertain or imprecise. It is therefore grounded in the brain’s bio-physical operation. Signs are ubiquitous bio-physical states, but they are not causal for the hosting organism. The paper contrasts brain-sign with consciousness both as theory, and in empirical findings. Brain-sign is the source of all theories, including itself.

  • Association between Dysthymic Disorder and Disability, with Religiosity as
           Moderator
    • Authors: Ravinder S. Sandhu; Samiran Ghosh; Timothy Dellenbaugh
      Pages: 13 - 19
      Abstract: There has been much research on Major Depressive Disorder (MDD) in terms of functional impairment associated with the disorder. On the other hand, Dysthymic Disorder (DD) has not received much attention in the literature in relation to the functional disability associated with the disorder. Similarly, the moderator effect of religiosity has been studied in many physical and mental health disorders, but has not been explored in DD. The aims of the present study were to explore the association between DD and functional disability, and to study the moderator effect of religiosity on the association. The data for the study was obtained from consortium of Psychiatric Epidemiologic Survey (CPES). The survey collected data on prevalence of mental health problems and the sociocultural determinants, in the national population. The present study utilized the data on DD and factors such as race, gender, marital status, employment status, and religiosity, in order to explore association between DD and disability and the effect of religiosity on the association. Results show that the subjects who have endorsed DD are 1.092 times more likely to have functional disability than those who have not endorsed DD. The association is statistically significant with the 95% CI for the Odds Ratio (OR) as 1.072–1.113. The religiosity has not shown a significant effect on the association between DD and functional disability. In conclusion there is statistically significant association between DD and the functional disability. Although the cross-sectional study design makes it difficult to determine the causal relationship, the results may signify that DD could potentially cause significant functional impairment. Further longitudinal studies are needed to probe the association between DD and disability.

  • Profile of Neurocognitive Functioning in Adults Infected with HIV
    • Authors: Anindita Mukherjee; Asmita Karmakar; Payel Dutta; Atanu Kumar Dogra
      Pages: 20 - 27
      Abstract: Since the very beginning of the course of infection, HIV enters into the CNS and it is reflected through neurological disorders. The aim of this study was to assess and subsequently compare the neurocognitive functioning of treatment-naive adults with HIV Stage I, II & peer control. Cross-sectional Case-control study design was followed. 22 adults (11 in stage I and 11 in stage II) with HIV infection and 11 adults as matched control were administered various standardised neuropsychological tests assessing cognitive functions like verbal fluency, executive functions, memory and visuo-spatial ability. Data were analysed by computing Kruskal Wallis one way ANOVA by ranks and post-hoc analysis (with the help of Mann Whitney U Test). Results showed that adults with HIV infected had poorer performance on most measures of memory functioning, visuo-spatial ability, verbal fluency and some measures of frontal lobe functioning in comparison to the matched peer control group. Those with stage II HIV had more compromised functions than those in stage I HIV in overall frontal lobe functioning along with inhibitory control, conceptualization, mental flexibility and sensitivity to interference.

  • Non-Traditional Interpretation of Conventional EEG Curve Analyses
    • Authors: Josef Faber; Mirko Novak; Zdenek Votruba; Michal Kovaljov
      Pages: 28 - 44
      Abstract: The electroencephalographic (EEG) curve is a highly complex formation representing cerebral system activities. On the one hand it may resemble featureless oscillations in alpha activity, on the other hand it looks like a very irregular tangle of mostly quite random lines even when the proband or patient is in a waking state. Recent findings also indicate that the EEG signal can be studied as a complex numerical series using signal analysis in terms of chaodynamic processes and describe its outcome as fractals or attractors. Using spectral Gabor analysis (GA), local coherence (LCA) and amplitude analyses (AA) we report results with regard to clinical experience and atractor character of epileptic activity. We have developed a simple coefficient method showing the state of EEG synchronisation and, at the same time, also the actual state of integration or complexity of the systems in the brain. Amplitude analysis shows the fractal feature of alpha activity and attractor descriptions related to of epileptic activity. These results might be useful for detection of mental states related to levels of wakefulness or somnolence.

  • Developments in the Neuroscience of Dreams
    • Authors: Bryony Shaw
      Pages: 45 - 50
      Abstract: Dreams and the act of dreaming have been subjects dismissed and discussed by great philosophers and psychologists for centuries. This paper explores developments in neuroscience as they relate to dreams, and how these developments help people in general understand better the role of dreams. The role of dreams and sleep are explored as they relate to mental health and affect regulation. Developments in neuroscience also help us understand the value of dream interpretation.
