There are four types of interneurons in the human eye: They are the amacrine cell, bipolar cell, horizontal cell and Müller cell.
Interneurons in the human eye form a complex network of interconnections between photoreceptor cells (i.e., rod and cone cells) and retinal ganglion cells.
Rod and cone cells are the photoreceptor cells in the human retina that respond to light.
Ganglion cells are the retinal neurons that receive and integrate visual information from photoreceptor cells and then transmit it to the brain via the optic nerve.
The complex network of interneurons in the human eye plays an important role in the processing and integration of visual information before transmitting it to the brain.
This network is also responsible for various visual functions, including spatial filtering, contrast enhancement, and colour opponent processing.
