Abstract

This article reports on research from the Autonomous University of Guerrero in Acapulco, Mexico, examining the role of dopamine and the dopaminergic system in drug addiction. The study highlights how drug addiction affects brain structures involved in reward and decision-making, particularly the ventral tegmental area and nucleus accumbens, where dopamine regulates reward-related behaviors. It explains that addictive drugs increase dopamine release, reinforcing the connection between substance use and pleasurable effects, while also altering dopamine receptor activity. The research aims to deepen understanding of the neurobiological mechanisms underlying addiction and related behaviors. [Extracted from the article]
