Novel experiences dampen previous memory representations in the hippocampus and prefrontal cortex, facilitating flexible strategy encoding in mice. Read More
A new study reveals specific brain regions that individually promote patience through the action of serotonin. Read More
Information flow between the ventromedial premotor cortex and medial prefrontal cortex makes it possible for monkeys to correctly identify social cues. Read More
Neurons in the medial prefrontal cortex respond more to loss than to gain. Avoidance of risk-taking is affected by an area of the hippocampus that is associated with memory and anxiety. The findings suggest a close relationship between memory processing and decision making when risk is present, especially in stressful situations. The fresh insights might help guide new psychiatric therapies for disorders marked by excessive avoidance, such as anxiety, and depression, and also mania and addiction, where excessive risk-taking is a common feature.

Social isolation experienced during childhood has an impact on adult brain function and behavior. Following two weeks of social isolation immediately following weaning in male mice, researchers noticed a failure in activation of medial prefrontal cortex neurons projecting to the posterior paraventricular thalamus during social exposure in adulthood. Findings suggest medial prefrontal cortex neurons required for sociability are profoundly affected by social isolation at a young age. Read More
Aging may alter neural processes for remembering continuous real-world experiences and segmenting memories. Read More
Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings. Read More
Study reveals how two neural circuits dictate the choice between social approach and avoidance. The network connecting the infralimbic cortex to the basolateral amygdala (BLA) impairs social behavior if there is a decrease in neural activity. Another network connecting the prelimbic cortex to the BLA similarly impairs social behavior if the neural activity is increased. Read More
In the medial prefrontal cortex, loneliness is associated with a reduced representational similarity between the self and others. Feeling socially disconnected may be mirrored by a self-representation of being a "loner." Read More
Loneliness alters how the brain represents relationships, a new study reports. Read More
The lateral hypothalamus is an integral component of social brain networks. It shapes socially motivated behaviors via functional coordination with neocortical regions. Read More
Scanning people's brains when watching videos, researchers found both neural and behavioral responses to the content could predict how long others would watch the same video on the internet. Read More
