1 kwi 2017 · The visual pathway shows a precise retinotopical organization at all levels that gives the anatomical background for symptoms when some part of optic pathway is damaged.
30/01/2019. Visual pathway consists of a series of cells & synapses that carry visual information from environment to brain for processing. Components : Retina → Optic nerve →Optic chiasma ↓ Optic tract ↓ Lateral geniculate body ↓ Geniculostriate tract ↓ Optic radiation to visual sensory area occipital lobe 17,18 &19.
27 lip 2023 · The visual pathway refers to the anatomical structures responsible for the conversion of light energy into electrical action potentials that can be interpreted by the brain. It begins at the retina and terminates at the primary visual cortex (with several intercortical tracts).
The visual pathways perform the function of receiv-ing, relaying, and ultimately processing visual informa-tion. These structures include the eye, optic nerves, chiasm, tracts, lateral geniculate nucleus (LGN) of the thalamus, radiations, striate cortex, and extrastriate association cortices.
The Visual System: Central Visual Pathways. Visual field representation. Each eye sees a part of the visual space that defines its visual field. The visual fields of both eyes overlap extensively to create a binocular visual field.
CALCARINE CORTEX: primary visual cortex. First real ANALYSIS of visual information; the cortex contains. neurones which respond to various features of the image; the neurons respond most strongly to edges of a particular orientation. This yields a decomposition of the image according to its edges.
Schematic diagram of the human visual pathways and their neuronal components. LGB Lateral geniculate body (modified after Krey et al. 1986; see “Further Reading”)
