In order to survive, animals must precisely regulate their approach and defensive behaviors towards threats. The periaqueductal gray (PAG), particularly its dorsal division, is a key hub in the innate defensive system, transforming sensory information into coordinated defensive motor responses. Neurons within the dorsal PAG exhibit distinct functional activity in relation to certain behaviors, and cells tuned to approach and escape from various threats have been reported. Despite its significance, the cellular and neurochemical identity underlying the functional heterogeneity of PAG neurons is
