Examples of ganglion cells include: During the late 1800s, early 1900s, Spanish Neuroscientist and Pathologist Santiago Ramón y Cajal proposed Neuron theory which basically introduced the idea that the Nervous system contained cells called the Neuron.

Through this study, he discovered that the ganglion cell distribution amongst vertebrates were pretty similar minus the Rods and cones in the retinas.

This data helped scientists get a better understanding of the ganglion cells present in the retinas of Mammals and Primates[3] In 1974, Boycott and Wassle created a scheme for the classification of Ganglion Cells that was found to be in the cat retina.

These cells, alpha, beta, delta and gamma are seen to be linked with the X,Y and W types of physiology.

Symptoms of individuals who are affected by Leber's Neuropathy include: Autosomal Dominant Optic Atrophy is a mutated gene in the autosomes (not sex-linked genes in humans chromosome pairs 1-22).
