Visual Performance And Synapses In Visual-Cortex Of Rabbits

The density of synaptic connections, the length of the contact zones and the number of synaptic vesicles are quantitatively studied in the left and right hemisphere of a group of rabbits a number of which showed marked ocular dominance. No systematic differences in the parameters studied could be observed in the visual cortex between symmetric animals, indicating that the ocular dominance cannot be explained by hemispheric differences in density of synapses.
