Santiago Ramón y Cajal’s neuron
This image, by Santiago Ramón y Cajal (1852-1934), was drawn from a histological stain of a human retinal cell and is among the first drawings of a neuron. Ramón y Cajal was the Spanish physician and early neuroscientist who first discovered that the nervous system was not continuous but was comprised of interconnected individual cells.
