Around 15% of amacrine cells are neither GABAergic or glycinergic. [2] These amacrine cells are sometimes known as nGnG amacrine cells, and it is thought that transcription factors that act on progenitors decide the fate of amacrine cells. One transcription factor that was found to be selectively expressed in nGnG amacrine cells is Neurod6 [5]

AII (A2) amacrine cells are a subtype of amacrine cells. Amacrine cells are neurons that exist in the retina of mammals to assist in interpreting photoreceptive signals. AII amacrine cells serve the critical role of transferring light signals from rod photoreceptors to the retinal ganglion cells (which contain the axons of the optic nerve).
Amacrine cells also produce lateral inhibition to bipolar cells [18] and ganglion cells to perform various visual computations including image sharpening. [19] The final visual signals will be sent to the thalamus and cerebral cortex , where additional lateral inhibition occurs.
The right lung is larger in size than the left, because of the heart's being situated to the left of the midline. The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as ...
The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here. [7]
The amacrine cells are placed in the inner part of the inner nuclear layer, and are so named because they have not yet been shown to possess axis-cylinder processes. Their dendrites undergo extensive ramification in the inner plexiform layer.
Bipolar cells effectively transfer information from rods and cones to ganglion cells. The horizontal cells and the amacrine cells complicate matters somewhat. The horizontal cells introduce lateral inhibition to the dendrites and give rise to the center-surround inhibition which is apparent in retinal receptive fields.
