addiction neuroscience

Addiction neuroscience studies how substances or behaviors can hijack the brain's reward system, which is responsible for feelings of pleasure and reinforcement. When a person engages in addictive behavior, such as drug use or gambling, the brain releases chemicals like dopamine, creating a surge of pleasure. Over time, repeated exposure alters the brain's wiring, making it harder to experience pleasure from everyday activities and increasing cravings for the addictive substance or behavior. This process can lead to compulsive behaviors, where the individual seeks out the addiction despite negative consequences, making recovery challenging.
