Introduction to Deep Learning

The study of how the brain works has fascinated scientists for long. This fascination got the wings with the advent of histology, unveiling how neurons are organized. The neuron doctrine states that the nervous system comprises independent neurons. However, earlier it was widely believed that the nervous system consists of a single continuous network, a theory proposed by Joseph von Gerlach and propounded by Camillo Golgi. Golgi also invented a staining technique that helped prove this theory wrong. Using this technique, Santiago Ramón y Cajal proved that the neurons are independent cells. The structure of neurons was also unveiled using this very staining technique. The term neuron was proposed by Heinrich Wilhelm Gottfried Waldeyer-Hartz in around 1891.
