Amacrine cells are
interneurons in the
retina. They are named from the Greek roots
a– ("non"),
makr– ("long") and
in– ("fiber"), because of their short neuritic processes. Amacrine cells are inhibitory neurons, and project their dendritic arbors to the
inner plexiform layer (IPL), there interacting with
retinal ganglion cells and/or bipolar cells.
