  • testosterone makes people overconfident and overly optimistic, with bad consequences.
  • Testosterone makes people cocky, egocentric, and narcissistic.
  • Testosterone does this by decreasing activity in the PFC
  • Dopamine is needed for place-preference conditioning to occur, and testosterone increases activity in the ventral tegmentum, the source of those mesolimbic and mesocortical dopamine projections. Moreover, conditioned place preference is induced when testosterone is infused directly into the nucleus accumbens, the ventral tegmentum’s main projection target. When a rat wins a fight, the number of testosterone receptors increases in the ventral tegmentum and accumbens, increasing sensitivity to the hormone’s feel-good effects.
  • rising testosterone levels increase Aggression only at the time of a challenge.
