For the most part, the chemical synapses made by amacrine cells are inhibitory, using either γ-aminobutyric acid (GABA) or glycine as neurotransmitters, but one type of amacrine cell, the starburst cell, releases acetylcholine and excites ganglion cells via nicotinic receptors.

It is well known that mammalian ganglion cells comprise more than a dozen types, clearly distinguishable from one another in structure and function.

The dendrites of ON ganglion cells stratify in the inner half of the inner plexiform layer (sublamina b, close to the cell bodies of the ganglion cells), while the dendrites of the OFF ganglion cells stratify in outer half (sublamina a, toward the bipolar cells). Therefore, agitation may also favor fibril morphologies that are more susceptible to fragmentation.

The various response types and responses of ganglion cells are discussed later. Both antibodies inhibited malaria invasion, but the latter gave rise to bizarre morphologies, the nature of which is unknown at present.
