Aragón in 1852 and died in Madrid in 1934.

became a medical officer with the Spanish army
and was sent to Cuba. Upon his return to Spain,
Ramón was appointed assistant of anatomy at the
Medical School of Zaragoza.
• Two years later, in 1877, he obtained his doctorate
from the Complutense University of Madrid and he
began to study the techniques of microscopic
observation.

Santiago Ramón y Cajal
• From 1888 on, Ramón y Cajal worked on the study of the
connections of the nerve cells, for which he developed his own
staining methods, exclusive for neurons and nerves, an
improvement on those created by Camillo Golgi. Thanks to
this, he managed to demonstrate that the neuron is the
fundamental constituent of nerve tissue...
• He also studied the structure of the brain and the cerebellum, the
spinal cord, the medulla oblongata and various sense centres of
the organism, such as the retina.
• His world fame increased when, in 1906, he won the Nobel Prize
for Physiology or Medicine for his discoveries about the structure
of the nervous system and the role of the neuron, a prize which he
shared with C. Golgi
