The effects of lesions in the spinal cord on the ability of the rat to discriminate differences in inclined planes.

Abstract

The behavior of rats with variable lesions in the spinal cord at the level of the 1st cervical vertebra was compared with that of a control group on an inclined plane discrimination box. No significant differences between the groups were obtained for either the learning of the problem or for the threshold of discrimination. The results indicate that in the operated animals the intact tracts of the cord were always sufficient to furnish the cues necessary for the learning of this kinesthetic problem.
