Preoptic thermoregulatory mechanisms in detail.
THE MAMMALIAN BRAIN COORDINATES a range of behavioral and autonomic control mechanisms that together regulate body temperature. These mechanisms are engaged in response to temperature perturbations, which may be sensed by either cutaneous or deep body thermal sensors. Key to these thermoregulatory processes are neurons in the anterior hypothalamuspreoptic area (POA) (10). This region contains n...
متن کاملThermoregulatory responses to preoptic cooling in unrestrained rabbits.
MCEWEN, G. N.,JR., AND J. E. HEATH. Thermoregulatory responses to preoptic cooling in unrestrained rabbits. 227 (4) : 954-957. 1974.Rabbits at ambient temperatures within the thermal neutral zone show two different metabolic responses to preoptic cooling. One response type is defined by a preoptic thermal sensitivity that shifts with ambient temperature and a “set point” that remains constant. ...

متن کاملVolitional vasomotor lability and vasomotor control.
This experiment tested the hypothesis that skin temperature variability during instructions to attempt skin temperature self-control without feedback (volitional vasomotor lability) predicts the acquisition of vasomotor control through biofeedback training. Skin temperature was recorded from the hands of 232 volunteers during a screening session. Twenty-three labile and 17 stabile subjects were...
متن کاملMidazolam minimally impairs thermoregulatory control.
Perioperative hypothermia usually results largely from pharmacologic inhibition of normal thermoregulatory control. Midazolam is a commonly used sedative and anesthetic adjuvant whose thermoregulatory effects are unknown. We therefore tested the hypothesis that midazolam administration impairs thermoregulatory control. Eight volunteers were studied on 2 days each, once without drug and once at ...
