Document Summary
Amacrine cells get information from bipolar cells and send it to other cells. Light has to pass through all the different cells en route to the receptors, but they are clear so the light does not get distorted. Ganglion cells form the optic nerve that exits the back of the eye, the part where it leaves is called the blind spot because it has no receptors. Don"t notice blind spot because brain fills in the gap and anything in the blind spot of one eye is visible to the other eye: fovea and periphery of the retina. Fovea is a tiny area specialised for acute, detailed vision; has few blood vessels and ganglion cells, but many receptors. Each receptor in the fovea connects to a single bipolar cell, which connects to a single ganglion cell (midget ganglion cell), with an axon to the brain.
