Document Summary

Closes sept 26 @11:59pm: 10 multiple choice questions, neural transmissions and the brain, chapter 3, assigned videos. October 3rd: all lecture material, all assigned videos, chapter (pp. 27-28, evolution of behaviour: chapter 2, chapter 3 (78-117) Testosterone: hormone produced by testes and adrenal glands, highest in males. Important for maturation of secondary sexual characteristeics: ex. September 25, 2018: castrating male rats (source of testosterone) decreases their tendency to fight. Injecting testosterone into castrated male rats reinstates their fighting behaviour: this proved that it was the testosterone, nothing else in the testes. Injecting testosterone into female rats increases their aggressiveness: not as aggressive as males but still aggressive, this study proved that in rats, testosterone regulates aggressiveness. Ironically, they found that the men were less aggressive than women. Increasing levels of testosterone in either men or women do not result in an increase in overt aggression: testosterone has different effects in humans and rats.
