Precisely timed activation of paraventricular hypothalamus oxytocin neurons in mice during low core body temperature resting states increases brown fat thermogenesis followed by behavioral arousal.
- Why it matters: Core body temperature is regulated across rest and arousal, but how PVN oxytocin neurons coordinate state-dependent shifts in both autonomic thermogenesis and behavior is unclear.
- What they did: The study measured in vivo PVN OT calcium dynamics across physiological states and used computer vision to track thermoeffector pathways, then applied precisely timed PVN OT stimulation during low-Tb rest.
- The result: PVN OT neurons were activated during social thermoregulation, and their calcium signals aligned with transitions from rest to thermogenesis and behavioral arousal in both social and non-social contexts, supporting a state-transition model.
