Striosomes, a collection of neurons in the brain's striatum, help with decision-making that requires the evaluation of risks and benefits.
Study identifies genes that become activated in the brain prior to the initiation of severe repetitive behaviors associated with addiction, ASD, and schizophrenia.
The decline of striosomal activity in the brain may explain why people lose the motivation to learn as they age.
Researchers report chronic stress can influence how we make decisions. In a new study, mice who were affected by chronic stress were more likely to make more risky decisions with higher payoff options than those who were less stressed.
Researchers have discovered connections withing the brain that appear to form a communication pathway between areas that control decision making, movement and emotion. They believe cells within the network could also be potential targets for Parkinson's disease.
Findings could have implications for treating psychiatric disorders that feature impaired decision making.
