Is it frequency-modualated or are different colors transmitted by different axons?
I know that each ganglion cell is connected to multiple photoreceptors. How does it tell the brain which photoreceptors are exactly activated and in what color?
Do ganglion cells correspond to particular colors?
Can one ganglion cell transmit different signals to the brain?
How the brain knows which color is light if signals of different receptors are mixed in the ganglion?
