Comparison of evoked potential changes during classical and instrumental conditioning in cats. 1986

V Csépe, and G Karmos, and M Molnár, and I Winkler

The waveform changes of cortical evoked potentials to click conditioned stimuli were analyzed by a complex computer program developed for sorting nonhomogeneous series of evoked potentials. The changes of evoked responses manifested themselves mainly in the middlelatency waves, while the first components showed only a slight fluctuation during the whole conditioning. A late negative component of 40-50 ms latency was clearly related to the attentive state of the animal. The evoked potentials with increased negative component appeared in different sequences in 'the two conditioning paradigms and in the different phases of the learning process.

UI	MeSH Term	Description	Entries
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.

D003214	Conditioning, Classical	Learning that takes place when a conditioned stimulus is paired with an unconditioned stimulus.	Reflex, Conditioned,Classical Conditioning,Classical Conditionings,Conditioned Reflex,Conditionings, Classical
D003216	Conditioning, Operant	Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
