WebThis pathway begins in the retina and travels through the lateral geniculate nucleus (LGN) of the thalamus before reaching the primary visual cortex (V1) in the occipital lobe of the brain. From there, the information is relayed to other brain areas such as the middle temporal area (MT) and the superior temporal sulcus (STS) responsible for ... Web29. avg 2013. · The feedback connections from the cortical middle temporal (MT) motion area, to layer 6 of the primary visual cortex (V1), have the capacity to drive a cascaded feedback influence from the layer 6 cortico-geniculate cells back to the lateral geniculate nucleus (LGN) relay cells.

Web30. okt 2013. · The primary visual area (V1) of the cerebral cortex is the first stage of cortical processing of visual information. Area V1 contains a complete map of the visual field covered by the eyes. It receives its main visual input from the lateral geniculate nucleus of the thalamus (LGN), and sends its main output to subsequent cortical visual areas … Web01. jun 2004. · In contrast, other areas receiving input from V1 represent higher processing levels and therefore cortico-cortical connections out of V1 are defined as feedforward …
