The fovea is a small depression in the retina where visual acuity is highest, responsible for sharp central vision, crucial for activities like reading and driving.

Amacrine Cell

A type of interneuron in the retina that plays a critical role in the visual signal processing by transferring information from bipolar cells to ganglion cells.

Ganglion Cell

Ganglion cells are neurons located in the retina that transmit visual information from photoreceptors to the brain via the optic nerve.

Bipolar Cell

Bipolar cells are a type of neuron found in the retina, acting as an intermediary between photoreceptors that detect light and ganglion cells that transmit visual information to the brain.
