Precortical physiology of colour vision. Multiple ganglion cell types express the a subunit of type II calmodulin-dependent protein kinase in the primate retina. This underdevelopment may be caused by several factors, including nutritional deficiencies and mutations in the KIAA gene on chromosome six.

The dendritic-field diameters of parasol cells within the nasal quadrant of the retina are not fully brought into line with those of cells lying elsewhere in the retina.
Parasol and midget ganglion cells of the human retina.
The lower branching midget ganglion cell with the larger dendritic tree is probably an ON center type. What we find more difficult to say is what spectral type of cone is connected in the midget bipolar to midget ganglion cell chain. Ahnelt P, Kolb H. Generate a file for use with external citation management software. Ciliary processes Ciliary muscle Pars plicata Pars plana. These cells are known as parasol retinal ganglion cells, based on the large sizes of their dendritic trees and cell bodies.
Inner plexiform layer - an overview | ScienceDirect Topics
In humans they are also known as P-cells because they project to the parvocellular layer of the lateral geniculate nucleus LGN. Where we can recognize S-cone blue pedicles on unusual morphological features Ahnelt et al. Dendritic field size and morphology of midget and parasol ganglion cells of the human retina. This information is integrated, processed, and sent via RGC axons in the optic nerve to visual centers in the brain Masland,
Retinal ganglion cell
Description: During normal visual processing, retinal ganglion cell RGC dendrites receive synaptic inputs from bipolar and amacrine cells in the inner plexiform layer. The entire contents of this site are copyrighted. Visual acuity starts with cone spacing and midget circuitry Visual acuity is a measure of our ability to discriminate the finest detail: Intracellular staining reveals different levels of stratification for on- and off-center ganglion cells in the cat retina. Thus, invaginating midget bipolar cells imb were found to connect with cone pedicles at central element, invaginating synapses at the cone pedicle ribbons Figs.
