Sex-linked neuroanatomical basis of human altruistic cooperativeness.
Human altruistic cooperativeness, one of the most important components of our highly organized society, is along with a greatly enlarged brain relative to body size a spectacular outlier in the animal world. The "social-brain hypothesis" suggests that human brain expansion reflects an increased necessity for information processing to create social reciprocity and cooperation in our complex soci...
متن کاملP43: Neuroanatomical Basis of Anxiety Disorders

The amygdala, the insula and anterior cingulate cortex seem to be critical, and all three have been referred to as the fear network .The amygdala which plays a fundamental role in neural network of fear...
متن کاملSex-Related Neuroanatomical Basis of Emotion Regulation Ability
Behavioral research has demonstrated that males have a higher capability of regulating their own and others' emotions than females; however, little is known about the sex-specific brain mechanisms involved in emotion regulation ability. In the present study, we used voxel-based morphometry to investigate the neural basis underlying emotion regulation ability in a large sample of young adults. A...

متن کاملThe neural basis of altruistic punishment.
Many people voluntarily incur costs to punish violations of social norms. Evolutionary models and empirical evidence indicate that such altruistic punishment has been a decisive force in the evolution of human cooperation. We used H2 15O positron emission tomography to examine the neural basis for altruistic punishment of defectors in an economic exchange. Subjects could punish defection either...
