During decision-making tasks, activation of two brain areas in rhesus macaques mirrors the same regions as in humans. The findings shed light on the neurobiological basis of cooperation and social interactions during decision-making tasks.
Children who exhibit less fear and desire for social connection, and who engage less in imitative behaviors, are more likely to develop callous-unemotional traits which may later lead to antisocial behaviors.
Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.
