Santiago Ramón y Cajal (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 17 October 1934) [ 1 ][ 2 ] was a Spanish neuroscientist, pathologist, and histologist specializing in neuroanatomy and the central nervous system. He and Camillo Golgi received the Nobel Prize in Physiology or Medicine in 1906. [ 3 ] Ramón y Cajal was the first ...
Ramón y Cajal's drawing of the cells of the chick cerebellum, from Estructura de los centros nerviosos de las aves, Madrid, 1905. The neuron doctrine is the concept that the nervous system is made up of discrete individual cells, a discovery due to decisive neuro-anatomical work of Santiago Ramón y Cajal and later presented by, among others, H. Waldeyer-Hartz. [1]
Drawing by Camillo Golgi of a hippocampus stained with the silver nitrate method Drawing of a Purkinje cell in the cerebellum cortex done by Santiago Ramón y Cajal, clearly demonstrating the power of Golgi's staining method to reveal fine detail. Golgi's method is a silver staining technique that is used to visualize nervous tissue under light ...
Pyramidal cells are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract. One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named. Other key structural features of the pyramidal cell are a single axon, a large apical dendrite ...
Interstitial cells of Cajal (ICC) are interstitial cells found in the gastrointestinal tract.There are different types of ICC with different functions. ICC and another type of interstitial cell, known as platelet-derived growth factor receptor alpha (PDGFRα) cells, are electrically coupled to smooth muscle cells via gap junctions, that work together as an SIP functional syncytium.

Camillo Golgi (Italian: [kaˈmillo ˈɡɔldʒi]; 7 July 1843 – 21 January 1926) was an Italian biologist and pathologist known for his works on the central nervous system. He studied medicine at the University of Pavia (where he later spent most of his professional career) between 1860 and 1868 under the tutelage of Cesare Lombroso.
A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the ...
The visual map theory by Santiago Ramón y Cajal proposes that the optic chiasm restores the retinal image on the visual cortex. [ 7 ] [ 8 ] Even though the theory is still supported, [ 4 ] several studies have pointed out the serious flaws in the theory.
