ganglion cell
Quick Summary
Ganglion cells are a type of neuron cell found in the human eye. These cells are crucial for processing visual information. They have receptive fields that connect with rods and cones, the light-sensitive cells in the retina.
Ganglion cells can respond to light in two main ways: an "on-response" when light hits the center of their receptive field, or an "off-response" when light is removed from the center. Some also exhibit directional sensitivity to moving light. The axons of ganglion cells form the optic nerve, transmitting visual signals to the brain.12
