A study of hungry mice sheds new light on the neurobiology of olfaction and food attraction. Researchers identified a pathway that promotes attraction to food odors over other olfactory cues. Read More
Study sheds new light on how the brain regulates hunger. The findings may help with the development of new drugs to fight obesity. Read More
Researchers have identified a specific node in the brain of mice that regulates vocalizations in response to social situations. If a similar location could be found in the human brain, researchers say it could potentially lead to new insight into social dysfunctions associated with autism and depression. Read More
Induced changes in the function of AgRP neurons may contribute to depression, researchers report. Read More
Exercise promotes the hypothalamus to release MOTS-c. Mitochondrial encoded MOTS-c interacts with the nuclear genome and regulates both cell metabolism and the stress response. Read More
Researchers found functional and anatomical differences in the brains of people who are more likely to embark on risky behaviors. Read More
Activity in the medial preoptic area tilts the mouse brain toward love and affection, while activity in the ventromedial hypothalamus is associated with more aggressive or hateful acts. Read More
Glutamatergic neural connections between the prelimbic prefrontal cortex and nucleus accumbens appear to be responsible for co-morbid anxiety and OCD behaviors. Read More
Oxytocin injections in rodent models directly activated SEG/GRP neurons via oxytocin receptors and influenced male sexual functions in the lumbar spinal cord. Reducing the activity of oxytocin receptors resulted in a decrease in sexual activity and ejaculatory response in the animals. Read More
Diet-induced changes to the reward system and innate differences may predispose mice to over-eating. Read More
Mouse study links specific autism types to abnormal parvocellular oxytocin neurons in the hypothalamus. Read More
Overactivity in the subgenual anterior cingulate cortex underlies several key symptoms of depression, anxiety, and heart disease. Read More
