BIOL 121 Lecture Notes - Lecture 8: Spatial Analysis, Retina, Stapes
Document Summary
Your visual field is what you can see. Each eye can see about 150 degrees. If this is true why cant we see 300 degrees: visual fields overlap. In the optic chiasm, ganglion cell axons originating from nasal retina cross to the contralateral side. All neocortex contains 6 layers ( i is on the surface and v1 is the deepest) V1 is the first place in the brain where cells receive signals from both eyes. Information processing: neurons are specialized to respond best to specific aspects of stimuli, these specializations can be demonstrated physiologically, by recording from neurons. Dorsal stream: where & how pathway, parietal cortex, spatial analysis, motion, visual control of movement. Ventral stream: what pathway, temporal complex, object and pattern identification. Sound is faster through water than it is through air because water is more dense. Measured in hertz (hz) - # of cycles/second. The difference in pressure between compressed air patched.
