Studies in somesthesis: IV. Role of somatic areas I and II in tactual "form" discrimination in the rat.

Abstract

After peripheral blinding, animals were trained to discriminate a wedge-shaped from a cylindrical lever, given a sham operation and after 13 days a retention test. Lesions were then made in Woolsey's somatic areas I and/or II, or in areas anterior or posterior to these somatic areas. Retraining was then carried out. Results showed no significant effect of lesions in any position within or outside of the somatic areas, on the discriminative function. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
