UNIT 1 Living organisms THE CONTRIBUTIONS OF RAMÓN Y CAJAL Natural Science 2. Secondary Education UNIT 1 The contributions of Ramón y Cajal Santiago Ramón y Cajal • He was born in Petilla de Aragón in Navarre in 1852. • He studied medicine at the University of Zaragoza, and was especially interested in anatomy and histology. • He served as an army doctor, but later became interested in the study of human tissue. Natural Science 2. Secondary Education UNIT 1 The contributions of Ramón y Cajal • Part of Santiago Ramón y Cajal’s research involved histological studies of nervous tissue, which, at that time was believed to be made up of a network of fibres. • To prove that nerve cells existed, Ramón y Cajal applied Italian scientist Camillo Golgi’s method of staining with silver nitrates to tissue samples taken from embryos. Natural Science 2. Secondary Education UNIT 1 The contributions of Ramón y Cajal • By perfecting staining with silver nitrates, Ramón y Cajal was able to identify entire neurons on his slides. • He observed that these cells were connected to each other despite the fact that they did not touch each other. • In May 1888, he published his many discoveries, which he backed up with high-quality slide preparations and impressive drawings. • In 1906, he was awarded the Nobel Prize for Medicine together with Camillo Golgi.
