Of the 4 cell groups of the interstitial nuclei of the anterior hypothalamus, the 3rd group ( in the preoptic-anterior hypothalamic area—or PO-AHA), is referred to as being responsible for sexual dimorphism in reference to sexual orientation. INAH-3 is generally found to be larger in the male brain than the female brain; however, this study indicates the region is smaller, in general, in homosexual males than in heterosexual males.
There are so many threats to our existence today and they bring me great anxiety at times. I struggle to stay positive but always try. When I first heard of the coronavirus, I felt panic set in. The worst thought that came to mind is the idea of losing loved ones and what may happen to my baby girl.
Maladaptive coping mechanisms fascinate me. Often times we know what we are doing hurts us but we do it anyway. Immediate stress relief is addictive. An entirely different part of the brain is responsible for impulsive behavior— as opposed to long term, carefully considered decision making. It’s our brain’s reward system. When we are used to using that part of the brain, I suppose it’s like exercising it.
