Role testosterone rules sapolsky the hormone testosterone in a person's aggressiveness; Link of testosterone to both sex and aggression; Increase in testosterone levels after testosterone rules sapolsky increase in Saliva testosterone level was positively correlated with height, and uncorrelated with measures of Role of testosterone in the development of the length of man's index finger in relation to his ring finger; Does testosterone make waves of electrical excitation surge down the stria terminalis?
Does it turn on that pathway?
If and only testosterone rules sapolsky the amygdala is already sending an excited volley down the stria terminalis, testosterone increases the rate of such activity by shortening the testosterone rules sapolsky time between bouts.
Just the interaction between the two. Do you want to know how important environment and experience are in understanding testosterone and aggression?
Look back at how the effects of castration are discussed earlier. There were statements like Remove the source of testosterone in species after species and levels of aggression typically plummet.

They had to grow up without the established social system to learn from.
This enthusiasm is typically reductive--because of physics envy, because reductionism is so impressive, because it would be so nice if there were a testosterone rules sapolsky gene or hormone or neurotransmitter or part of the brain responsible for everything.
This is no mere academic subject.
We are a fine species with some potential, yet we are racked by sickening amounts of violence. Unless we are hermits, we feel the threat of it, often every day, and should testosterone rules sapolsky leaders push the button, we will all be lost in a final global violence.
