Incorporating Information From Neuroscience And Endocrinology Regarding Sexual Orientation Into Social Work Education, Jill Littrell
jill l littrell Dr.
The brains of heterosexual males and heterosexual females are different. Moreover, the brains of gay men are similar to heterosexual females whereas the brains of lesbians are similar to heterosexual males. Neuroscience research supporting these postulates is reviewed. The gestational processes that might explain the differences in brain structure and function corresponding with gender are reviewed. Following a discussion of the physiological bases for sexual orientation, a discussion of the physiological bases for the expression of gender related traits and a discussion of factors contributing to sexual identity are provided. Throughout the article, alternative ways to think about gender are …

This study investigated mechanisms for the stressor-induced changes in muscle fatigability in men and women. Participants performed an isometric-fatiguing contraction at 20% maximal voluntary contraction (MVC) until failure with the elbow flexor muscles. Study one (n = 55; 29 women) involved two experimental sessions: 1) a high-stressor session that required a difficult mental-math task before and during a fatiguing contraction and 2) a control session with no mental math. For some participants (n = 28; 14 women), cortical stimulation was used to examine mechanisms that contributed to muscle fatigability during the high-stressor and control sessions. Study two (n = 23; …
