NEUROBIOLOGY AND NEUROCHEMISTRY OF IMPULSIVE BEHAVIOR

Abstract

Trying to establish a concrete definition of impulsivity continues to generate great debates among the different authors. As a manifestation it is considered a predisposition to rapid and unplanned reactions in the presence of different stimuli. Neurobiology gives a full explanation to this behavior by integrating the relationship of response, reflection and decision making that contribute to impulsivity. The most important characteristic, therefore of this behavior, is an inadequate ability to assess the consequences of their behavior and the immediate search for the reward. Alterations in various areas of the brain, both in its structure and in the modulation of its neurotransmitters, could explain the presence of this behavior. This article aims to review different studies regarding the scientific basis that supports the explanation of the phenomenon of impulsive behavior with a neurobiological and neurochemistry basis.
