Webb1 okt. 2000 · Thermoregulation In the late 1800s and early 1900s, several lesion and stimulation studies identified the rostral hypothalamus as an important neural structure in the regulation of body temperature [ 1–10 ]. The compilation of years of lesion studies suggests that no single neural area acts as the center for thermoregulation [ 11–13 ]. WebbThermoregulation is an example of negative feedback. The hypothalamus in the brain is the master switch that works as a thermostat to regulate the body’s core temperature ( Figure 24.23 ). If the temperature is too high, the hypothalamus can initiate several processes to lower it.
WebbThermoregulation is a splendid example of the integrative functioning of the human hypothalamus. Autonomic neural circuitry, adaptive behavioral responses, endocrine, and other hypothalamic regulatory functions are recruited and blended automatically to accomplish thermal balance necessary for the close regulation of body temperature.
