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] The term neuron (spelled neurone in British English) was itself coined by Waldeyer as a way of identifying ...
Sir Charles Scott Sherrington OM GBE FRS FRCP FRCS [1] [3] (27 November 1857 – 4 March 1952) was a British neurophysiologist.His experimental research established many aspects of contemporary neuroscience, including the concept of the spinal reflex as a system involving connected neurons (the "neuron doctrine"), and the ways in which signal transmission between neurons can be potentiated or ...
For projections from one region of the nervous system to another, see neural pathway. A neural circuit is a population of neurons interconnected by synapses to carry out a specific function when activated. [ 1 ] Multiple neural circuits interconnect with one another to form large scale brain networks. [ 2 ]
Gordon M. Shepherd. Gordon Murray Shepherd (21 July 1933 [1] – 9 June 2022) [2] was an American neuroscientist who carried out basic experimental and computational research on how neurons are organized into microcircuits to carry out the functional operations of the nervous system. Using the olfactory system as a model that spans multiple ...
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 ...
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 ...
History of neuroscience. From the ancient Egyptian mummifications to 18th-century scientific research on "globules" and neurons, there is evidence of neuroscience practice throughout the early periods of history. The early civilizations lacked adequate means to obtain knowledge about the human brain. Their assumptions about the inner workings ...
Law of specific nerve energies. The law of specific nerve energies, first proposed by Johannes Peter Müller in 1835, is that the nature of perception is defined by the pathway over which the sensory information is carried. Hence, the origin of the sensation is not important. Therefore, the difference in perception of seeing, hearing, and touch ...
