The process of how both error and reward signals are organized within the cerebral cortex are revealed by researchers.
Why is it so much fun to hang out with our friends? Why are some people so sociable while others are loners or seemingly outright allergic to interactions with others? A new study by researchers at the Stanford University School of Medicine begins to provide an answer, pinpointing places and processes in the brain that promote socialization by providing pleasurable sensations when it occurs.
Behavioral Experiments show that women are more generous than men. Now, researchers at the UZH have been able to demonstrate that female and male brains process prosocial and selfish behavior differently. For women, prosocial behavior triggers a stronger reward signal, while male reward systems respond more strongly to selfish behavior.
The brain’s reward processing system fluctuates through the day, peaking in the morning and evening.
