Google celebrated the birthday of Santiago Ramón y Cajal who is considered the ‘Father of Neuroscience’ for demonstrating that independent nerve cells, or neurons, make up the nervous system.

In 1906, he shared the Nobel Prize in Physiology or Medicine with Camillo Golgi, an Italian scientists who pioneered effective staining methods for nervous tissue.

The Google Doodle celebrating Ramón y Cajal was also shown in other Spanish-speaking countries, including Mexico and Venezuela.

Scholarpedia has an excellent article about Ramón y Cajal, his life, and his work—complete with his drawings and images of his original preparations of neurons.
