(anatomy)
An interneuron located in the inner plexiform layer of the vertebrate retina that influences retinal signal processing in response to visual stimuli at the level of contact between the bipolar and ganglion cells.

This is an inhibitory circuit driven by amacrine cells, whose appearance and numbers vary among individuals and species.
(1988) Retinal bipolar cells receive negative feedback input from GABAergic amacrine cells.
Together, the two neurobiologists have demonstrated what is also suspected for amacrine cells in the mammalian retina: It is possible that numerous isolated microcircuits exist in a single nerve cell.

It protected striatal cells in culture cells against quinolinic acid excitotoxicity (24) and retinal amacrine neurons against AMPA-induced excitotoxicity in vivo via CB1 receptor mechanism (25).
Retinal radial serial sections (10 mm thick) were obtained by a cryomicrotome (Kryostat 1720, Leitz Wetzlar) to localize the RGCs, excluding the displaced amacrine cells of the inner plexiform layer.
"There are 50 kinds of amacrine cells, the drug cabinets of the retina, and most of them likely release multiple neurotransmitters that can influence the retinal circuit," Diamond said.
The INL includes the nuclei of the bipolar, horizontal, amacrine, and Muller cells.

Instead of the the eye's bipolar, horizontal and amacrine cells, which process the information gathered by the rods and cones, the electronic retina has "signal transfer gates, memories, logic gates and driver circuits,' each on its own silicon layer.
This procedure enables only the RGCs be located, thus excluding the displaced amacrine cells.
In addition, neural abnormalities such as morphological alterations in astrocytes, decreased cholinergic and dopaminergic amacrine cells, and increased inflammatory leukocytes have also been observed in this model [10, 17, 68, 69].
