Abstract
Removal of 1 [Macaca mulatta] eye before birth permanently changes the cellular organization and synaptic connectivity of visual centers in the primate brain. Notable alterations occur. The lateral geniculate nucleus develops only 2 cellular layers and 1 interlaminar fiber band instead of the normal 6 layers and 5 bands. Aberrant synaptic connections are formed between the intact eye and the geniculate neurons that have lost their normal input. Ocular dominance columns fail to develop in the visual cortex.
