Warm-Sensitive Neurons that Control Body Temperature
Thermoregulation is one of the most vital functions of the brain, but how temperature information is converted into homeostatic responses remains unknown. Here, we use an unbiased approach for activity-dependent RNA sequencing to identify warm-sensitive neurons (WSNs) within the preoptic hypothalamus that orchestrate the homeostatic response to heat. We show that these WSNs are molecularly defi...
متن کاملInsulin Causes Hyperthermia by Direct Inhibition of Warm-Sensitive Neurons
OBJECTIVE Temperature and nutrient homeostasis are two interdependent components of energy balance regulated by distinct sets of hypothalamic neurons. The objective is to examine the role of the metabolic signal insulin in the control of core body temperature (CBT). RESEARCH DESIGN AND METHODS The effect of preoptic area administration of insulin on CBT in mice was measured by radiotelemetry ...
متن کاملWarm Body Temperature Facilitates Energy Efficient Cortical Action Potentials
The energy efficiency of neural signal transmission is important not only as a limiting factor in brain architecture, but it also influences the interpretation of functional brain imaging signals. Action potential generation in mammalian, versus invertebrate, axons is remarkably energy efficient. Here we demonstrate that this increase in energy efficiency is due largely to a warmer body tempera...
متن کاملWarm sensitive neurons of the preoptic area regulate ambient temperature related changes in sleep in the rat.
Warm sensitive neurons (WSN) play a major role not only in body temperature regulation, but also in sleep regulation. The present study was undertaken to investigate the role of WSN of the preoptic area (POA) in mediating the ambient temperature (T(amb)) related changes in sleep. The effect of T(amb) changes on sleep and body temperature was studied in rats before and after destruction of WSN o...
متن کاملCentral control of body temperature
Central neural circuits orchestrate the behavioral and autonomic repertoire that maintains body temperature during environmental temperature challenges and alters body temperature during the inflammatory response and behavioral states and in response to declining energy homeostasis. This review summarizes the central nervous system circuit mechanisms controlling the principal thermoeffectors fo...
