WebApr 15, 2013 · Sensing Temperature Researchers discovered that distinct sets of neurons respond to heat and cold. The findings provide an elegant explanation for how mammals sense temperature. Thermosensation — the ability to detect temperature — triggers our reflex to withdraw from painful heat or cold. WebJan 4, 2024 · In this study, we identified subsets of temperature-activated neurons in two hypothalamic nuclei, the preoptic area (POA) and the dorsomedial hypothalamus (DMH), and showed that modulating their activity can lead to alterations in core temperature. WebThe temperature response of hypothalamic neurons can be altered by a number of nonthermal factors such as glucose concentration and osmolality. Silva and Boulant 4 showed that a large number of preoptic warm-sensitive neurons are also sensitive to osmolality and that many preoptic cold-sensitive neurons are also sensitive to glucose … taxi 5 streaming hd
