Responses of anterior hypothalamic-preoptic neurons to direct thermal stimulation during wakefulness and sleep. 1983

P L Parmeggiani, and A Azzaroni, and D Cevolani, and G Ferrari

The responses of anterior hypothalamic-preoptic units to direct thermal stimulation were studied during wakefulness and sleep in cats. Seventy-nine percent of the selected units showed changes in firing rate in relation to wakefulness and sleep stages. Forty-nine percent of the units characterized by activity related to EEG patterns were found to be responsive to thermal stimulation in wakefulness and synchronized sleep. Unit responses to thermal stimulation were either absent or inconsistent in desynchronized sleep.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
