HSC 350 Lecture Notes - Lecture 2: Retinal Ganglion Cell, Outer Plexiform Layer, Ganglion Cell Layer
Document Summary
Light travels from the optic nerve; from the ganglion cell layer toward the pigment epithelium. 2: outer nuclear layer, outer plexiform layer. Fovea = area of retina specialized for high visual acuity in the center of the macula; contain high density of cones. The fovea is the location of high visual acuity in the center of the macula; contain high density of cones. In the fovea, there is high level of cones compared to the peripheral side of the retina (i. e. temporal and nasal periphery) There is no such thing as color in the physical world just a spectrum of visible wavelengths of light that are reflected by object around us. Colors by the brain based on our subjective experience. Conversion of light into neural signals occurs in the photoreceptors. Rod = greater number of disks and higher photopigment concentration 1000 times more sensitive to light than cones.
