The association of limbic system activation with dream, bad dream and nightmare generation
… generation, with a particular focus on the limbic system. High versus low levels of limbic activation and its effect on the frequency of dream, bad dream, and nightmare recall, characteristics, and content were investigated using retrospective and prospective measures. Psychosocial stress – …

Vasopressin decreases excitability in rat lateral amygdala neurons through inhibition of hyperpolarization-activated cationic current.
The amygdala is a critical part of the limbic system with important roles in social behavior. Abnormal activity in the lateral amygdala nucleus (LA) has been implicated in several disorders, including autism spectrum disorder (ASD) in which abnormal social functioning is a primary symptom. The …

The Dynamic Functional Capacity Theory: Music Evoked Emotions
… the inhibitory release of sensory cortices, the limbic system, the reward-circuit, and the brainstem reticular activating system, causing 'unbridled' activation of these areas. This process produces extremely intense emotions. This theory may provide music-evoked emotion researchers and Music …

Memory tests for use with brain damaged adults in a multiracial general hospital : a preliminary validation study
… with diagnoses implying disorders of the limbic system was compared with that of 35 normal controls matched for race, age, intelligence and sex. Discriminant analysis of the verbal and visual test scores achieved 100% correct classification of the 27 patients with bilateral damage, but 3% …

Executive Attention, Action Selection and Attention-Based Learning in Neurally Controlled Autonomous Agents
… upon Norman and Shallice's supervisory attention system, incorporates important features of human attentional control: selection of an intended task over a more salient automatic task; priming of future tasks that are anticipated; and appropriate levels of persistence of focus of attention. …

Mechanisms of fatigue during prolonged exercise in the heat
… central fatigue including the basal ganglia and limbic system.

Distributed Control Of Multi-Agent Systems Using Biologically-Inspired Reinforcement Learning
… the real-time flocking control of Multi-Agent Systems (MAS) in presence of system uncertainties and dynamic environment. To handle the impacts from system uncertainties and dynamic environment, a novel reinforcement learning technique, which is appropriate for real-time implementation, has been …

Assessment of sex differences and amphetamine on schedule-induced polydipsia
… to increase synaptic dopamine levels in the mesolimbic reward pathway, which in turn causes behavioral effects in animals, and subjective effects in humans. These reinforcing properties of AMPH trigger very strong levels of craving the drug, and eventually result in patterns of compulsive use of …

Strength of family bond predicts disrupted neural habituation to visual familial threat in adolescence
… regarding how they uniquely impinge on neural systems involved in adaptive threat processing. METHODS: MVPA analysis of fMRI data was used in a novel way to measure disrupted neural habituation in a threat network comprising nodes of the limbic system across several classes of stimuli including …

Tinnitus, physical activity and improved quality of life: investigation of the neural correlates of tinnitus and potential treatment options
… quality of life, anxiety and depression. The limbic system is the focal region of the brain involved in the emotional reaction to stimuli. However, few studies have directly targeted this system to understand neural mechanisms of tinnitus distress or successful habituation. Physical activity …

Examining the Association between Brain MRI Measures at 7 Tesla and cognition following COVID-19 Infection
… within subcortical brain structures of the limbic system were related to neurological, respiratory, psychiatric, and gastric symptoms experienced during the acute phase of illness. Cognitive and neuropsychological evaluations were performed in 45 participants who experienced neurological …

Temporal Lobe Transients and Prayer
… of brief, micro-seizures that originate in the limbic system and affect the temporal lobes of the brain. According to this theory, ritual behavior could be used by individuals to induce micro-seizure activity. The theory predicted that an increase in alpha and theta activity in the temporal …

Bridging the link between trauma, brain development and depression: epigenetic mechanisms
… We studied differences in the fronto-limbic system (a collection of areas responsible for emotion regulation) and methylation at the serotonin transporter (SLC6A4) and FK506 binding protein gene (FKBP5) genes (two genes strongly linked to stress regulation and depression). Second, how …

Role of the ventral tegmental area, cannabinoid receptors and GABA neurons in motor activity
… provide important forebrain control over the limbic system. The present series of studies explored these VTA neurons from two perspectives: First, we explored the VTA as a potential site of action for cannabinoid receptors (CB1R) and provide the first detailed analysis of the distribution of …

Multiscale Genomic Analysis of the Corticolimbic System: Uncovering the Molecular and Anatomic Substrates of Anxiety-Related Behavior
… The amygdala is a principle component of the limbic system that controls emotionality. Using BXD recombinant inbred (RI) mice as model organisms, the anatomy and cellular architecture of the amygdala—specifically, the basolateral amygdala (BLA)—was examined to assess the level of structural …

Role of Microglial α7 Nicotinic Acetylcholine Receptor Positive Allosteric Modulator in Neuroinflammatory Pain Models in Mice
… with neuroinflammatory pain. As a part of the limbic system, hippocampus is known to play a critical role in pain perception and processing, and is densely populated with microglial cells and α7 nicotinic acetylcholine receptors (nAChRs). Given the role of microglial α7 nAChRs in …
