Decision-making is a fundamental cognitive process that shapes human behavior and guides everyday actions. Recent advancements in neuroimaging techniques have provided unprecedented insights into the neural mechanisms underlying decision-making processes. This article reviews findings from neuroimaging studies investigating decision-making across different domains, including economic choices, social interactions, and moral dilemmas. By elucidating the brain regions and neural circuits involved in decision-making, researchers have begun to unravel the complex interplay between cognition, emotion, and reward processing. The implications of these findings for understanding decision-making deficits in neuropsychiatric disorders and informing interventions are discussed.
