New research from cognitive neuroscientists at Brown and Radboud Universities has pinpointed how stimulants such as Ritalin and Adderall can change people’s motivation to complete difficult tasks.
Researchers at Brown University found that stress early in the life of female mice leads to fewer “tuning” neurons in the part of the brain responsible for making sense of emotions and following rules.
Researchers report, contrary to popular belief, Adderall and other ADHD drugs do not improve cognition in healthy college students. Instead, they may impair cognitive function.
New research concludes that humans’ ability to identify and categorize what they see is kept up-to-date by reactivating lessons learned and allowing them to become stable over time.
Brown University researchers have shown that reinforcement learning and working memory — two distinct brain systems — work hand-in-hand as people learn new tasks.
