Facilitated early cortical processing of nude human bodies

摘要: a b s t r c Functional brain imaging has identified specialized neural systems supporting human body perception. Responses to nude vs. clothed bodies within this system are amplified. However, it remains unresolved whether and processed by same cerebral networks or processing of recruits additional affective arousal areas. We recorded simultaneous MEG EEG while participants viewed photographs bodies. Global field power revealed peak ∼145 ms after stimulus onset both bodies, ∼205 exclusively Nude-body-sensitive responses were centered first (100-200 ms) in the extrastriate fusiform areas, subsequently (200-300 affective-motivational areas including insula anterior cingulate cortex. conclude that visibility sexual features facilitates early cortical purpose which is presumably trigger behavior ultimately ensure reproduction.
