[Reaction of caudate nucleus neurons to direct stimulation]. 1976

G M Gruzdev, and V S Zelenskaia

Extracellular recording from the caudate nucleus neurons were performed in experiments on immobilized cats during electrical stimulation of different parts of the same nucleus. Latencies varied from 3.5 to 40 msec. Most neurons could be excited by stimulation of the most rostral part of the caudate nucleus head. In most cases responses were independent of the stimulation place. The responses consisted of one or rarely two spike followed by inhibition of background activity. Then activity gradually restored without rebound. Afterdischarges were not observed. The caudate neurons hardly reproduced stimulating frequencies more than 30 per second and retained in most cases their own frequency level (on the average 5-15 spikes/sec.). The results are discussed in connection with participation of the caudate nucleus in the origin of spindle activity.

D011930	Reaction Time	The time from the onset of a stimulus until a response is observed.	Response Latency,Response Speed,Response Time,Latency, Response,Reaction Times,Response Latencies,Response Times,Speed, Response,Speeds, Response
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.
