Behavioral auditory function after transection of crossed olivo-cochlear bundle in the cat. V. Pure-tone intensity discrimination. 1979

M Igarashi, and J L Cranford, and E A Allen, and B R Alford

This report describes the cat's ability to discriminate pure-tone intensity differences after transection of the crossed olivo-cochlear bundle at the floor of the fourth ventricle. Cats were trained by behavioral (avoidance) conditioning to detect intensity difference above 75 dB re 0.0002 dyne/cm2 of 10 000 Hz tones, using the repetitive method. Postoperative comparison of data from 5 experimental animals and 5 sham-operated control animals showed minimal differences which reflects merely functional biological variance. Neurohistological examination confirmed the accuracy of the lesion placement.

D010897	Pitch Discrimination	The ability to differentiate sound frequency or pitch.	Discrimination, Pitch,Pitch Discriminations
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.

D003056	Cochlear Nerve	The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.

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.
