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. Read More
Researchers analyzed the relationship between reward and effort in achieving goals and identified two critical stages in the decision-making process. Read More
Reward does not improve visual perception learning unless it is followed by a good night's sleep. Read More
Fear extinction memories and feelings of reward are both stored in neurons that express the Ppp1r1b gene in the posterior of the basolateral amygdala. Read More
When faced with complex choices, people show bursts of exploration before settling into preferred options of higher value. Read More
Inflammation appears to reduce reward response in females. Reduced activity in the brain's reward system is a key component of anhedonia, the loss of enjoyment in activities, a core feature of depression. The findings may explain why depression is more prevalent in women than in men. Read More
Positive reinforcement by reward is important for learning based behaviors, but masks the expression of underlying knowledge and true animal intelligence. Read More
Unexpected rewards boost memories of specific events. The findings may have implications for treating memory problems associated with depression. Read More
Hippocampal replay selectively enhances memory of highly rewarded locations in a familiar context. Read More
People are more confident in decisions, and execute choices more quickly, if they are chasing a reward. However, we become more flexible in our decisions when trying to avoid a negative outcome. Read More
A new role for the hippocampus involving pattern separation and conjunctive representation in reinforcement learning is discussed. Read More
