Document Summary

Overview of topics: beyond the retina: 2 pathways to v1, subcortical structures (lgn & sc, primary visual cortex: lines, direction, colour, m vs. p pathways: movement vs. particulars, object & face recognition. Brain organization schemes: rgcs: dot detectors, v1: line orientation, motion, colour, v4: shapes, temporal lobe: objects & faces. Contralaterality in vision right brain & vice versa, but no. Instead: one might think info from left eye goes to, information from left half of visual eld goes, that is, everything to the left of what you"re ( rst) to right half of brain & vice versa. Eye to cortex: geniculocortical pathway, lateral geniculate nucleus (lgn) of thalamus to v1, 90% of rgc outputs, tectopulvinar pathway, superior colliculus (aka tectum ) to pulvinar, 10% of rgc outputs nucleus to visual cortex (many parts) The lgn: laterality, red: receive signals from the ipsilateral eye, blue: receive signals from the contralateral eye, pathways (aka channels, solid: parvocellular layers, dotted: magnocellular layers.
