What role does GABA neurotransmitter play in substance use according to the behavioral view?

The correct answer highlights the role of GABA (gamma-aminobutyric acid) as a neurotransmitter in reinforcing pleasure and promoting continued substance use. In the context of the behavioral view, GABA is primarily recognized for its inhibitory effects within the central nervous system. When substances lead to an increase in GABA activity, they can enhance feelings of relaxation and euphoria, which, in turn, produces pleasurable experiences for the user. This positive reinforcement encourages individuals to continue using the substance to replicate those pleasurable feelings.

Research suggests that drugs which boost GABA activity, such as alcohol and benzodiazepines, may initially provide a sense of relief or pleasure, reinforcing the behavior of seeking out such substances. The cycle of reinforcing pleasurable experiences can lead to a pattern of use that increases the risk of developing a substance use disorder.

Understanding GABA's role is crucial for those studying the psychological and neurobiological underpinnings of addiction, as it contributes to the way the brain processes rewards and can affect decision-making regarding substance use.
