Document Summary
2/7/17 vision: every sensory system has a primary area in the cortex, every sensory system has a relay nucleus in the dorsal thalamus, light has wavelength (tells color) and amplitude (tells brightness, intensity, reflection, refraction, absorption. Color perception: cone opsins are red, green, or blue and sensitive to certain wavelengths. Dark and light adaptation: bleached rods in sun need time to adjust to darkness, retinal configuration needs to change. Retinal processing: light opsins bipolar cells ganglion cells axons to optic nerve, light = no opsins releasing nt. Inhibits the on bipolar cell: causes excitation, light = no nt. 2/13/17: v1=striate cortex = area 17, dorsal stream = where, ventral stream = what, layer 3 = output to cortex v2 and mt, layer 4 = lgn input, layer 5/6 = subcortical output superior colliculus, lgn. If area on brain is stimulated, feel sensation.
