Abstract:

Helping another person is usually described as a moral or social act. Neuroscience adds a less obvious possibility: under some conditions, helping may also alter the helper’s own affective and physiological state. This narrative review examines the emerging neurobiological literature on prosocial behavior, with particular attention to reward valuation, empathy and mentalizing, caregiving-related processes, threat regulation, social connection, and autonomic–immune pathways. Rather than treating altruism as a single brain function, the article argues for a network perspective in which prosocial action recruits partially overlapping systems for representing another person’s state, assigning value to possible actions, selecting a response, and learning from its consequences. Recent reviews suggest that helping can engage reward-related and caregiving processes while potentially buffering threat and supporting social connectedness; however, effects depend on context, voluntariness, cost, relationship, individual differences, and the form of helping. The article proposes the CARE model—Connect, Appraise, Respond, Encode—as a cautious conceptual framework for organizing these mechanisms without claiming a dedicated “altruism center” in the brain. It also distinguishes healthy prosociality from compulsive self-sacrifice and discusses implications for neuroscience, prevention, organizations, and future longitudinal and experimental research. The central conclusion is deliberately modest: helping others is not a neurological prescription for happiness, but prosocial behavior may constitute one biologically meaningful route through which social connection, reward, stress regulation, and well-being interact.
