People with schizophrenia and social anhedonia exhibit altered neural processing for social reward processing, leading to impaired social interaction and social dysfunction.
Study reveals how reward enhances connectivity between the ventral striatum and the default mode network, impacting behavior.
Switching off activity in the anterior cingulate cortex prevented marmoset monkeys from making an association between behavior and a particular outcome.
Dopamine neurons in the midbrain become active in a previously undetected way when an animal considers a reward that is changing in value.
Researchers found specific neurons in the striosome that help mice learn to avoid negative experiences.
Compared to adults, children continue to explore other options than using knowledge to capitalize on reward, to see if the value has changed. Children approach exploration systematically to make sure they don't miss anything.
Older children have stronger neural responses to rewards over punishments later in the afternoon. In younger children, this pattern is reversed.
Cannabis use in males appears to alter sperm before mating, increasing the risk of their offspring developing brain abnormalities in areas associated with mood, memory, learning, and reward.
