Web1) Magnocellular pathway 2) Parvo-interblob pathway 3) Blob pathway The magnocellular pathway (4 things) 1) Begins with M-type ganglion cells of the retina 2) M-type ganglion cells of the retina send axons to the magnocellular layers of the LGN 3) The magnocellular layers of the LGN project to layer IVCα of striate cortex WebIt also receives projections from layer IV B in the primary visual area (V1)—a layer that, interestingly enough, is part of the magnocellular channel involved in analyzing the movement of objects. This channel also maintains its specificity for movement in area V2, where it is concentrated in the thick stripes that contain large amounts of cytochrome …

WebVisual Perception Is a Constructive Process. Visual Perception Is Mediated by the Geniculostriate Pathway. Form, Color, Motion, and Depth Are Processed in Discrete Areas of the Cerebral Cortex. The Receptive Fields of Neurons at Successive Relays in an Afferent Pathway Provide Clues to How the Brain Analyzes Visual Form WebAnother parallel line of research at the brain level established the hypothesis that DD present deficits in the magnocellular pathways and part of the posterior cortical attentional network involved in eye movement control 7 7 Castro SM, Salgado CA, Andrade FP, Ciasca SM, Carvalho KM.
