There, amacrine cells additionally contribute to retinal processing before an action potential is produced by the RGC. It is the bipolar cell in the retina that connects a photoreceptor to a retinal ganglion cell (RGC) in the inner synaptic layer. The change in membrane potential alters the amount of neurotransmitter that the photoreceptor cells release onto bipolar cells in the outer synaptic layer. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. The retina is composed of several layers and contains specialized cells for the initial processing of visual stimuli. The posterior cavity is filled with a more viscous fluid called the vitreous humor. The posterior cavity is the space behind the lens that extends to the posterior side of the interior eyeball, where the retina is located. It is filled with a watery fluid called the aqueous humor. The anterior cavity is the space between the cornea and lens, including the iris and ciliary body. The eye is also divided into two cavities: the anterior cavity and the posterior cavity. The innermost layer of the eye is the neural tunic, or retina, which contains the nervous tissue responsible for photoreception.
