The male advantage in 5-HT2 receptors seems to derive particularly from frontal and cingulate cortices Biver et al.
Our work in rats also shows that such sex differences in MePD astrocytes critically depend on functional androgen receptors ARs since MePD astrocytes in male rats with defective ARs are completely feminized Johnson et al. Curr Opin Neurobiol ; 7 : —
Brain sex differences amygdala damage in Kansas City B, Biological Sciences. Technical Report A A review from the perspective of large-scale brain networks hypothesized that women's higher susceptibility to stress-prone diseases such as posttraumatic stress disorder and major depressive disorderin which the salience network is theorized to be overactive and to interfere with the executive control networkmay be due in part, along with societal exposure to stressors and the coping strategies that are available to women, to underlying sex-based brain differences.

The findings, which appear in the journal NeuroImagemay help researchers better understand sex-based differences in the emergence of mental disorders during adolescence and early adulthood.
It was not possible to fully cross arousal and valence because the IAPS set does not include high arousal neutral or low arousal valenced images. Neurobiology of Learning and Memory.
