Behavioral auditory function after transection of crossed olivo-cochlear bundle in the cat. IV. Study on pure-tone frequency discrimination. 1979

M Igarashi, and J L Cranford, and Y Nakai, and B R Alford

The present report describes the frequency discrimination capability of the cat based on behavioral auditory measurements in conjunction with transection of the crossed olivo-cochlear bundle at the floor of the fourth ventricle. Using the repetitive method, cats were trained to respond to frequency differences from 8000 Hz. For the measurement of the frequency discrimination threshold, instead of using the descending method, the cats were trained to detect the absolute change in the frequency. With the given experimental paradigm, the average pre- and post-operative frequency discrimination thresholds were 114.3 Hz and 133.6 Hz in experimentals, and 128.3 Hz and 140.0 Hz in shams. Differences between the two groups were minimal and may simply represent functional biological variance.

D009847	Olivary Nucleus	A brainstem nuclear complex. in the hindbrain, also referred to as the olivary body. The olivary nuclear complex is a part of the MEDULLA OBLONGATA and the PONTINE TEGMENTUM. It is involved with motor control and is a major source of sensory input to the CEREBELLUM.

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.
