Kathy, I have a great deal of background in neurophysiology, vision, and vision research. I've been out of a few years, so I can't say I'm up on all the latest. But to start with, you seem a might bit confused, as usual. It was Ray,not me, who was saying the eye was just a passive receptor of light, did no processing of vision, and contained no nervous tissue. Further there were two-way connections from the brain back to the retina by which the brain was supposedly telling the eye what it could see or not see. Supposedly research in kittens backed him up. But, even though maybe I'm becoming a dinosaur, the last I heard: 1. The retina is indeed embryologically derived from the brain, has two very well defined and studied neural layers that indeed do early processing of vision, one layer of which (ganglion cells) creates the axons that form the nerve fibers making up the optic nerve itself. (You can't have a nerve going from one place to another without neurons to create that nerve.) By all means, Kathy, list some of the latest "advances" that back up Ray's version instead. 2. Nobody has yet found reciprocal nerve connections in humans between retina and cortex, certainly no way for the brain to bully the retina into seeing only what the brain wants it to see if it isn't connected to it to begin with. Please correct me with the latest "advances" if I am wrong about this. 3. The kitten research shows that visual deprivation in young kittens (also baby monkeys) causes permanent damage to the animals' vision, including greatly decreased visual acuity and loss of binocular vision. This is also reflected histologically in the layout and numbers of the neurons in the visual cortex connected to a deprived and non-deprived eyes and neurophysiologically in the properties of the neurons (e.g. loss of binocularly driven cells, loss of cells responding to fine detail, loss of ability to detect orientation of edges). Please tell me which of the latest "advances" in this kitten research instead demonstrates that these deprived kittens have brains bossing their retinas around. Awaiting your references.
