A diferenciação do cérebro masculino e feminino

Abstract: A diferenciação anatômica, psíquica e emocional entre os gêneros masculino e feminino é bastante complexa e envolve os fenômenos biológicos referentes à genética e à ação dos esteroides sexuais, além dos fenômenos epigenéticos, os quais atuam simultaneamente para promover ou eliminar a diferenciação dos circuitos neurais cerebrais entre os sexos 1 . Em especial, o conhecimento sobre os aspectos biológicos da formação da identidade de gênero é bastante restrito, uma vez que a maioria dos estudos sobre a anatomi… Show more

“…The abusive supplementation of AASs has been associated with a large number of collateral psychiatric effects (panic, depression/anxiety, and obsessive-compulsive disorders or hyperactivity). This may result in negative behavioral changes, including some sexual disturbances, given that it also acts on the pre-optic area, a region of the brain responsible for sexual behavior (14). There is evidence that AASs users present more hostile behavior, as well as symptoms of somatic disorders, depression, and anxiety, together with paranoia (15), which could even lead to suicide, in some cases (16, 17).…”

“…Vários estudos recentes demonstram que as mulheres expostas a rostos que são classificados como atractivos activam zonas do cérebro de recompensa e essa activação neural é parcialmente modulada pelo estado hormonal das mulheres (Lara & Romão, 2013). Estudos mostram ainda através de fMRI, que os homens mostram activação em centros de recompensas cerebrais em resposta a corpos femininos nus quando o ICQ é de .7 com gordura corporal redistribuída.…”
