This feed focuses mechanisms underlying addiction and addictive behaviour including heroin and opium dependence, alcohol intoxication, gambling, and tobacco addiction.
The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.
Attention is involved in all cognitive activities, and attention disorders are reported in patients with various neurological diseases. Here are the latest discoveries pertaining to attention disorders.
Neurons in the basal forebrain play specific roles in regulating feeding. Here are the latest discoveries pertaining to the basal forebrain and food avoidance.
Basal forebrain is a region in the brain important for production of acetylcholine and is the major cholinergic output of the CNS. Discover the latest research on circuits in the basal forebrain here.
The neuronal circuits within the cortico-limbic brain regions form networks that mediate emotional behavior. Areas specific to emotional learning include the basal amygdala and sublenticular extended amygdala region along with a supplemental motor area. Discover the latest research on brain circuits in emotional learning here.
This feed focuses on collision avoidance behaviors including guiding locomotion, obstacle avoidance, and steering behaviour. Here is the latest research in this domain.
Deep Brain Stimulation is a neurosurgical procedure that uses a neurostimulator to stimulate specific regions of the brain for treatment of movement disorders. Here is the latest research.
This feed focuses on neurocognitive development of motivated behaviour with focus on intrinsic drive and the reward system. Here is the latest research.
Dopamine is a neurotransmitter and a hormone commonly associated with the brain's pleasure and reward system. Here is the latest research on its role in affecting and guiding human behaviour.
Midbrain dopamine neurons have long been implicated in mediating reward behavior and the motivational aspects of feeding behavior. Here are the latest discoveries pertaining to dopamine and feeding.
This feed focuses on projection neurons in the brain which are responsible for synthesis and release of neurotransmitter dopamine.
Gene-environment interaction is when two different genotypes respond to environmental variation in different ways.Genes and environment interact to form an individual's personality. Abnormal or extreme behaviour could thus be explained by hereditary factors in combination with poor environmental conditions.
Habituation, the gradual waning of an evoked behavioral response with repeated stimulation, is a basic and universal form of learning. This feed explores the genetic networks that are involved in the occurence of habituation.
This feed focuses on the high throughput technologies used to dissect the genetics of behavior and their associated disorders. Discover the latest research here.
Hippocampal neurogenesis is the formation of new neurons from neural progenitor cells in the dentate gyrus. This is important for behavioural responses, learning and memory. Here is the latest research on hippocampal neurogenesis.
We discuss modulators of leptin and the leptin receptor as they relate to normal cognitive functioning and may mediate some of the actions of leptin in the brain. Here are the latest discoveries pertaining to leptin in the brain.
The limbic system is comprised of several different parts of the brain involved in emotion, motivation, learning, and memory. Discover the latest research on the limbic system here.
Despite widely reported clinical and preclinical studies of rapid antidepressant actions of NMDA receptor antagonists, there has been very little work examining the effects of these drugs in stress models of depression that require chronic administration of antidepressants or the molecular mechanisms that could account for the rapid responses. Discover the latest research here.
Neurons within the central nervous system receive signals that regulate feeding and metabolism. Here are the latest discoveries pertaining to neural circuits in regulating feeding.
Dopamine neurons in the ventral tegmental area (VTA) are a critical part of the neural circuits that underlie reward learning and motivation. Discover the latest research here.
Studies have reported important roles for subpopulations of gabaergic cells in the regulation of both feeding and arousal. Here are the latest discoveries pertaining to neural circuits in stress and feeding.
This feed focuses on physiological and in silico neural networks involved in processes that affect emotions.
Hunger is regulated by specialized neural circuits that transform brain signals into behaviors. Here are the latest discoveries pertaining to the neurobiology of hunger.
This feed focuses on neural manifestations, neurocognitive development, and cognition disorders that affect behavior. Here is the latest research.
Opioids work on opioid receptors to relieve pain and other medical symptoms. Here is the latest research on the therapeutic role of opioids and opioid receptors in pain management.
Chronic pain and addictive disorders present significant medical and public health problems; both are underdiagnosed and inadequately treated. The cooccurrence of pain and addiction adds complexity to the assessment and treatment of both disorders. Discover the latest reserch on pain and addiction here.
Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
The effects of stress on several conditions including cardiovascular disease, cancer, and psychiatric disorders differ between sexes. Sex-specific effects of stress can also occur prenatally and impact placental function and fetal development. Here are the latest discoveries pertaining the sex-specific effects of stress.
Sexual dimorphism of neurons shows quantitative differences in cell number, gene expression and other features. Sexual dimorphism of neurons within the brain underlie behavioral sex differences, but individual function of the sexually dimorphic neurons is poorly understood. Here is the latest research on sexual dimorphism in neuronal activity.
Social behavior circuits of the basal forebrain and midbrain are deeply conserved (from an evolutionary perspective), and particularly similar in birds and mammals. Social behaviors include personality and paternal and maternal behavior. Here are the latest discoveries pertaining to social behavior circuits.
