[Number of retinal ganglion cells and visual discriminative performance in split-chiasma rats].
The relationship between post-operative retention, learning and transfer of visual discriminative tasks and number of retinal ganglion cells undegenerated after chiasma section was analyzed with a multiple linear regression program, stepwise procedure. Post-op retention of an intensity discrimination task significantly depends on the number of retinal ganglion cells in the most spared eye. Post-op learning and transfer of an orientation discrimination task significantly depends on 1) the total number of undegenerated ganglion cells and 2) their uniform distribution in both eyes.
