Neurons located in the middle layer of the retina that act as intermediaries between photoreceptor cells (such as rods and cones) and ganglion cells, playing a crucial role in the primary processing of visual information.

Amacrine Cells

Neurons found in the retina that operate at the inner synaptic layer and play a critical role in the regulation of visual signal processing and the integration of visual information.

Horizontal Cells
