Final answer:
Parvocellular-X OFF cells are a type of retinal ganglion cells that respond to changes in light. When a light is turned off, there is a decrease in firing rate of these cells.
Step-by-step explanation:
Parvocellular-X OFF cells are a type of retinal ganglion cells found in the eye.
These cells are responsible for transmitting visual information from the retina to the brain. When a light is turned off, there is a decrease in firing rate of Parvocellular-X OFF cells. It is important to note that Parvocellular-X OFF cells respond best to changes in light rather than a constant light stimulus.
Therefore, the firing rate of these cells remains low until the light goes off.
