  • Physical exercise and catecholamine reuptake inhibitors affect orienting
           behavior and social interaction in a rat model of
           attention-deficit/hyperactivity disorder.

    • Free pre-print version: Loading...

      Abstract: The effects of methylphenidate (MPH), atomoxetine (ATMX), and/or physical exercise (EX) on orienting behavior and social interaction were examined in spontaneously hypertensive rats (SHRs), a commonly used animal model of attention-deficit/hyperactivity disorder (ADHD). During the orienting procedure, rats received repeated presentations of a nonreinforced visual stimulus. As observed previously, orienting behavior (rearing up on the hind legs) habituated across trials in normo-active control rats (Wistars) but not in SHRs, suggesting that SHRs have difficulty ignoring irrelevant behavioral stimuli. Treatment with MPH (0.125 mg/kg), ATMX (0.125 mg/kg), or EX (3 weeks of access to a running wheel), alone or in combination, reduced rearing behavior in SHRs to the level observed in the Wistar control group. Similarly, drug treatment and/or EX reduced the number of social interactions exhibited by SHRs, while having no effects on locomotor activity. It is important to note that EX was just as effective as MPH or ATMX in reducing orienting behavior and social interaction. In contrast to the SHRs, neither MPH nor ATMX affected orienting or social behavior in Wistar rats. Together, these findings support the growing literature that EX may be useful as an adjunctive or replacement therapy in ADHD. (PsycInfo Database Record (c) 2021 APA, all rights reserved)

  • In vivo microdialysis shows differential effects of prenatal protein
           malnutrition and stress on norepinephrine, dopamine, and serotonin levels
           in rat orbital frontal cortex.

    • Free pre-print version: Loading...

      Abstract: Prenatal protein malnutrition (PPM) alters the developing brain including changes in monoaminergic systems and attention. In the present study, we used in vivo microdialysis to examine the relationship between PPM, acute stress, and extracellular serotonin (5HT), dopamine (DA) and norepinephrine (NE) in both hemispheres of lateral orbital frontal cortices (lOFC) in the adult rat. We hypothesized that prenatal protein malnutrition would alter extracellular concentrations of cortical monoamines. The effects of an acute restraint stress were also assessed because PPM alters the brain’s response to stress. We used adult male, Long-Evans rats [10 prenatally malnourished (6% casein) and 10 prenatally well-nourished (25% casein)]. Samples were collected from the left and right hemispheres of the lOFC every 20 min for 6 hr total and quantified using high-performance liquid chromatography (HPLC). After 2 hr of sampling, animals were exposed to a 40-min restraint stress. Extracellular levels of NE were significantly higher in PPM animals than in well-nourished controls across both hemispheres at all time-points. In contrast, baseline levels of 5HT and DA levels did not differ between nutritional groups. 5HT levels, but not NE or DA levels, were elevated compared to baseline levels in both nutritional groups and in both hemispheres during the first 20 min of stress exposure. These data highlight the impact of PPM on neuromodulatory systems and the profile of changes in response to acute stress. Additional studies are needed to determine how these basal and stress-related responses impact cognitive performance and whether these differences persist during cognitive testing.

  • Endogenous hippocampal, not peripheral, estradiol is the key factor
           affecting the novel object recognition abilities of female rats.

    • Free pre-print version: Loading...

      Abstract: Estradiol (E2) is involved in the regulation of emotional behavior, cognitive function, and neuroplasticity. However, peripheral E2 and central E2 levels do not always fluctuate together. The relationships of peripheral and central E2 with cognitive function are not clear. The aim of this study was to investigate whether peripheral E2, hippocampal E2, or both play a critical role in novel object recognition (NOR), and whether Kalirin-7, an important regulator of spine plasticity, is involved in the modulation of E2 on cognitive behavior. Our results showed that ovariectomy (OVX) significantly reduced serum E2 levels in the 14 weeks following the procedure. However, hippocampal E2 levels did not decrease in the OVX group compared to the sham group until after 14 weeks. Consistent with the changes in hippocampal E2 levels, the investigation ratio in the NOR test and hippocampal Kalirin-7 expression was also not lower in the OVX group than in the sham group until 14 weeks after the procedure. To confirm the relationship between hippocampal E2 levels and NOR ability, we inhibited the production of hippocampal E2 via microinjection of letrozole (LTZ; an aromatase inhibitor) into the hippocampi of rats in the control group and 8-week OVX group. The data indicated that a reduction in E2 levels in the hippocampus significantly impaired NOR ability and simultaneously decreased Kalirin-7 levels in the hippocampus. In conclusion, our study strongly demonstrates that hippocampal E2, but not peripheral E2, plays a critical role in NOR ability and that Kalirin-7 may be involved in this mechanism.

  • The costs of coping: Different strategies to deal with social defeat
           stress might come with distinct immunologic, neuroplastic, and oxidative
           stress consequences in male Wistar rats.

    • Free pre-print version: Loading...

      Abstract: The impact of stress on health and well-being is determined by the ability of an individual to cope with challenges imposed by the stressor. Animals exposed to social defeat stress show different patterns of response during confrontations, leading to distinct stress-induced consequences. Using an established resident–intruder paradigm, we explored the outcomes of adopting active or passive coping strategies during a social defeat protocol over peripheral and central nervous system (CNS) levels of inflammatory cytokines, growth factors, glucocorticoid, and oxidative stress markers in male Wistar rats. Animals that presented short latency to assume a defeated posture during confrontation—considered as susceptible to stress—exhibited increased levels of brain-derived neurotrophic factor (BDNF) in the amygdala (AMY) and in the bed nucleus of the stria terminalis (BNST), and decreased lipid peroxidation in the CNS, suggesting changes in antioxidative defenses as well as stress-induced neuroadaptations. On the other hand, animals with longer latencies to assume a submissive posture—considered to be resilient to stress—presented lower levels of CNS BDNF compared to short-latency animals and decreased enzymatic antioxidant defenses in the CNS in comparison to controls, which might indicate an increased risk of central oxidative damage. From the results, behavioral reactivity cannot be considered a predictor of success in responding to stress; however, the findings of this study reinforce the idea that exposure to stress has no predetermined negative effects.

  • Social buffering of plasma corticosterone and amygdala responses of young
           rats following exposure to periorbital shock: Implications for eyeblink
           conditioning development.

    • Free pre-print version: Loading...

      Abstract: The developmental onset of aversive learning processes depends on complex interactions between endocrine, neural, and social influences. Emergence of avoidance conditioning in rat pups is triggered by elevated plasma corticosterone activating the amygdala. Further, the mother’s ability to buffer the corticosterone response delays the onset of avoidance in ˜2-week-old pups. Eyeblink conditioning (EBC) also develops during the pre-weaning period. In previous work, little or no conditioning was observed on Day 17 for pups housed in the home cage with mother and littermates between training sessions, whereas pups isolated between training sessions did show some conditioning. This suggests that social buffering may also delay the onset of this form of aversive learning. In the present study with Day-17 pups, one session of periorbital shock, the typical EBC unconditioned stimulus for young rat pups, resulted in lower plasma corticosterone levels and neural activity in the central nucleus of the amygdale (CeA) of pups returned to the mother and homecage following the session as compared to pups isolated following the shock session. These findings demonstrate social buffering of the physiological response to aversive stimulus exposure under conditions of EBC and support the hypothesis that social buffering of early adverse experience may adjust the timing of emergence of EBC in rat pups.

  • Aversive outcomes impact human olfactory discrimination learning and
           generalization.

    • Free pre-print version: Loading...

      Abstract: Learning associations between sensory stimuli and outcomes, and generalizing these associations to novel stimuli, are a fundamental feature of adaptive behavior. Given a noisy olfactory world, stimulus generalization holds unique relevance for the olfactory system. Recent studies suggest that aversive outcomes induce wider generalization curves by modulating discrimination thresholds, but evidence for similar processes in olfaction does not exist. Here, we use a novel olfactory discrimination learning paradigm to address the question of how outcome valence impacts associative learning and generalization in humans. Subjects underwent discrimination learning, where they learned to associate odor mixtures with either aversive (shock) or neutral (air puff) outcomes. We find better olfactory learning for odors associated with aversive compared to neutral outcomes. We further show that generalization gradients are also modulated by outcome valence, with the shock group exhibiting a steeper gradient. Computational modeling revealed that differences in generalization are driven by a narrower excitatory gradient in the shock group, indicating more discriminatory responses. These findings provide novel evidence that olfactory learning and generalization are strongly affected by the valence of outcomes. This adaptive mechanism allows for behavioral flexibility in novel situations with related stimuli and with outcomes of different valences. Because odor stimuli differ considerably from one encounter to the next, adaptive generalization may be especially important in the olfactory system.

  • The relationship of age and hypertension with cognition and gray matter
           cerebral blood volume in a rhesus monkey model of human aging.

    • Free pre-print version: Loading...

      Abstract: The goal of this study was to investigate whether alterations in cerebral microvasculature, as measured by cerebral blood volume (CBV), contribute to age- and hypertension-related impairments in cognitive function with a focus on executive function and memory. Data were collected on 19 male rhesus monkeys ranging from 6.4 to 21.6 years of age. Hypertension was induced through surgical coarctation of the thoracic aorta. We assessed whether performance on tasks of memory and executive function corresponded to CBV in either the hippocampus or prefrontal cortex. We found a relationship between duration of hypertension and CBV in the gray matter of the prefrontal cortex, but not the hippocampus. No relationships were found with the degree of hypertension or age. Increased prefrontal CBV was related to greater impairment in executive function while hippocampal CBV was not related to memory performance. These findings suggest that duration, but not severity, of hypertension or age are important factors underlying alterations in brain microvasculature and that executive function is more vulnerable than memory function.

  • The primacy of behavioral research for understanding the brain.

    • Free pre-print version: Loading...

      Abstract: Understanding the brain requires us to answer both what the brain does, and how it does it. Using a series of examples, I make the case that behavior is often more useful than neuroscientific measurements for answering the first question. Moreover, I show that even for “how” questions that pertain to neural mechanism, a well-crafted behavioral paradigm can offer deeper insight and stronger constraints on computational and mechanistic models than do many highly challenging (and very expensive) neural studies. I conclude that purely behavioral research is essential for understanding the brain—especially its cognitive functions—contrary to the opinion of prominent funding bodies and some scientific journals, who erroneously place neural data on a pedestal and consider behavior to be subsidiary.

  • A reminder before extinction failed to prevent the return of conditioned
           threat responses irrespective of threat memory intensity in rats.

    • Free pre-print version: Loading...

      Abstract: After retrieval, reactivated memories may destabilize and require restabilization processes to persist, referred to as reconsolidation. The reminder-extinction procedure has been proposed as a behavioral reconsolidation-based intervention to persistently attenuate threat-conditioned memories. After the presentation of a single reminder trial, the conditioned threat memory may enter a labile state, and extinction training during this window can prevent the return of conditioned threat responses. However, findings on this reminder-extinction procedure are mixed and its effectiveness may be subject to boundary conditions, including memory strength. Here, we systematically investigate whether more intense threat memories are less susceptible to disruption through a reminder-extinction procedure. Using a Pavlovian auditory threat conditioning procedure at three different shock intensities, rats acquired conditioned threat responses of variable “strength.” Rats subsequently underwent either extinction preceded by a reminder or standard extinction. Although different shock intensities led to different strength threat memories, all groups showed reinstatement of conditioned threat responses irrespective of shock intensity or reminder condition. Hence, regardless of the intensity of the threat memory, the reminder procedure was ineffective in preventing the return of threat responses in rats. We thus find no evidence that threat memory intensity is a potential modulator of the effectiveness of the reminder-extinction procedure. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
