Episode notes

A mouse is able to move around in its cage, freely moving, even though it has a little tether. This little thin wire is actualy alitt what we call optrode. And the mere pressing of a button will activate a little bit of light released at the end of that wire. That light ats particular neurons. In this case, it's the ostrogen receptor, containing neurons in only the ventromedial hypothalmus. The female mice are either in a receptive phase or a non receptive phase of their so called estra cycle. They don't have a menstral 28 day cycle. They have an extra cycle. On certain days of the estra cycle,

This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones—estrogen and testosterone—in mediating violent and and/or competive aggression. I also describe tools that can be used to modulate the factors that have been shown to ‘prime’ an individual for aggression, including sunlight, estrogen sensitivity, competition within social settings, and overall stress levels, and the hormone cortisol. I discuss how substances such as caffeine and alcohol can impact impulsive behaviors, and how nutrition and supplementation can be used to regulate mood and aggression.
