Interneurons in the retina that play a crucial role in the visual processing pathway by modulating the signal between bipolar and ganglion cells.

Bipolar Cells

Neurons present in the retina of the eye that play a crucial role in transferring visual signals from photoreceptor cells to ganglion cells.

Photoreceptors

Cells in the retina of the eye that respond to light, crucial for vision.

Ganglion Cells

Neurons located in the retina that receive visual information from photoreceptors via intermediate bipolar cells and transmit it to the brain.
