Fundamental neurobiological research as outlined in this chapter, together with findings from clinical and behavioral and social science research (see chapter 4), are providing researchers with neurobiological answers that offer better ways to understand, prevent, or treat drug addiction. The neurobiological mechanisms for alcoholism discussed here of course are not definitive, and as in most diseases with behavioral manifestations inherent biological abnormalities may contribute to the expression of the behavior but are not the only factors involved. The neurobiology of emotion neural systems, the amygdala, and fear is emotion a magic product, or is it a physiologic process which depends on an anatomic mechanism.

Recent research suggests that people with antisocial personality disorder (aspd) may be more prone to alcohol-related aggression than people without aspd as a group, people with aspd have higher rates of alcohol dependence and more alcohol-related problems than people without aspd.

  • In a new study, scientists from epfl's brain mind institute, led by professor carmen sandi, have identified some of the key neurobiological mechanisms that control aggression.
  • To elucidate the neurobiological mechanisms that underlie abnormal alcohol-seeking behavior, it is necessary to have experimental animals that would orally self-administer alcoholic solutions, (for the drug properties of ethanol) in amounts comparable to that in the human alcoholic.
