WebIn neuroanatomy, the optic radiation (also known as the geniculocalcarine tract, the geniculostriate pathway, and posterior thalamic radiation) are axons from the neurons in the lateral geniculate nucleus to the primary visual cortex.The optic radiation receives blood through deep branches of the middle cerebral artery and posterior cerebral artery.. They … WebThe dotted line represents the efferent pathway; the solid line represents the afferent pathway. A light stimulating the left retina generates impulses that travel up the left optic nerve and divide at the chiasm. Some impulses continue up the left tract; some cross and continue up the right tract.
