Anatomical asymmetry of the cerebral hemispheres of the cat brain.
The fissure patterns of 39 cat brains were examined and each hemisphere was classified according to the scheme of Otsuka and Hassier. Of the 33 brains for which there was no ambiguity of classification for either hemisphere, 45 percent were asymmetrical. Included among these asymmetrical brains was that of a newborn kitten.  As the asymmetry is focussed predominantly in the region of the visual cortex, it is suggested that this may form the substrate of the functional asymmetry in visual discrimination performance previously demonstrated in cats.
