Mechanisms for survival: vagal control of goal-directed behavior

Trends Cogn Sci. 2023 Nov 29:S1364-6613(23)00278-4. doi: 10.1016/j.tics.2023.11.001. Online ahead of print.ABSTRACTSurvival is a fundamental physiological drive, and neural circuits have evolved to prioritize actions that meet the energy demands of the body. This fine-tuning of goal-directed actions based on metabolic states ('allostasis') is deeply rooted in our brain, and hindbrain nuclei orchestrate the vital communication between the brain and body through the vagus nerve. Despite mounting evidence for vagal control of allostatic behavior in animals, its broader function in humans is still contested. Based on stimulation studies, we propose that the vagal afferent pathway supports transitions between survival modes by gating the integration of ascending bodily signals, thereby regulating reward-seeking. By reconceptualizing vagal signals as catalysts for goal-directed behavior, our perspective opens new avenues for theory-driven translational work in mental disorders.PMID:38036309 | DOI:10.1016/j.tics.2023.11.001
