[Responses of caudate nucleus neurons to acoustic stimulation during functional blockade of the centrum medianum of the thalamus in the cat]. 1986

A N Litvinova

Responses of caudate nucleus to sound clicks (0.5/s) were recorded extracellularly in chronic experiments on cats under conditions of functional blockade of centrum medianum. Analysis of average poststimulus histograms has shown that functional blockade of centrum medianum in 30% of the caudate nucleus neurons induced a decrease in phasic activating responses to sound signals and in 52% of neurons their disappearance. A decrease in the level of spontaneous caudate nucleus neurons activity was also found. Direct pathways from centrum medianum to caudate nucleus are discussed for their significance in transmission of sound signals to caudate nucleus neurons.

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.
