Lecture 26 Receptive fields of P and M cells: -P cells are receptive to specific color, M cells are specific to any color, not specific to particular wavelength Retinal function can be divided into fovea/periphery and dark/light systems Dimensions of human visual field: *full: 180 degrees *binocular visual: 120-overlap between right eye and left eye *monocular: 30 degrees-each eye that the other can’t see Object in left visual field: View w/ left nasal, right temporal Visa versa w/ right visual field Left hemisphere processes left sides of both left and right eye *Damage to optic nerve on one side will cause damage to corresponding eye *Damage to optic chiasm will result only binocular vision, no monocular vision will be able to be seen *after optic nerve, damage is done in the contralateral visual field LGN: -6 layers; each layer is monocular; receives innervation from only one eye -first 4 layers: P type, last 2 layers: M type -P ganglion cell (4 layers, 2 ipsi and 2 contra)
