Document Summary
Light travels through: the cornea, the aqueous humor (fluid chamber, the pupil, the lens, the vitreous humor (fluid filled chamber) long, thin, cylindrical cells that are highly sensitive to light. Our visual system detects differences in light intensity, not absolute amounts of light. Center-surround organization serves to emphasize areas of difference (contrast) The receptive field: the part of the retina in which a stimulus with a particular set of properties can cause the neuron to respond with a train of action potentials. Neurons in the nervous system are not quiescent, most cells fire spontaneously (including ganglion cells. Center-surround structure of ganglion receptive fields (rfs: want to know location and characteristics of a receptive field, ganglion cells are attuned to differences (center/surround contrast, on center ganglion cells, off center ganglion cells. If you cut the optic chiasm: blind in the nasal hemi retinas (closest to your nose)
