摘要

Survival requires organisms to continuously balance competing motivational drives, including the need to acquire energy, avoid threat, and navigate complex social environments. Feeding, anxiety-related behaviors, and social interactions are therefore tightly interconnected, yet the neural mechanisms that coordinate these domains remain incompletely understood. The lateral hypothalamus (LH) is uniquely positioned to integrate internal metabolic signals, external environmental cues, and socially relevant information, and to translate this integrated state into appropriate behavioral responses. Once viewed primarily as a regulator of feeding, the LH is now recognized as a highly heterogeneous structure comprising intermingled neuronal subpopulations that influence reward seeking, stress responses, arousal, and social behavior. Emerging evidence indicates that these distinct but overlapping circuits dynamically allocate behavioral resources between energy acquisition, social interactions and overcoming anxiety, enabling flexible adaptation to changing internal and external demands. In this review, we discuss how LH circuits coordinate feeding, social behavior, and anxiety, and propose that this region functions as a central hub for balancing competing motivational states.
