Starburst amacrine cells are a type of amacrine cells found in the retina. [1] These interneurons are notable for co-releasing acetylcholine and GABA . [ 1 ]
GABAergic amacrine cells are usually wide field amacrine cells and are found in the ganglion cell layer (GCL) and the inner nuclear layer (INL). One type of GABAergic amacrine cell that is fairly well studied is the starburst amacrine cell.
The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
Using fMRI brain imaging, scientists found three main areas stimulated by colour: V1, an area in the ventral occipital lobe, specifically the lingual gyrus, which was designated as human V4, or hV4, and another area located anteriorly in the fusiform gyrus, designated as V4α. [4] [6]

the eye on the opposite side (the contralateral eye) sends information to layers 1, 4 and 6. This description applies to the LGN of many primates, but not all. The sequence of layers receiving information from the ipsilateral and contralateral (opposite side of the head) eyes is different in the tarsier . [ 10 ]
The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain. In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus , consisting of a frontal and parietal portion. [ 2 ]
In terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann area 17. [3]In primates, the extrastriate cortex includes visual area V3, visual area V4, and visual area MT (sometimes called V5), [3] while V1 corresponds to the striate cortex, and V2 to the prestriate cortex.
