A neuron is a cell which is part of the nervous system. Neurons send messages to and from the brain. Information is transferred along each neuron by means of an electrical impulse. see also motor neurone disease. a type of cell that makes up the nervous system and sends messages to other parts of the body or the brain = nerve cell. or nerve cell Any of the cells of the nervous system. Sensory neurons relay information from sense organs, motor neurons carry impulses to muscles and glands, and interneurons transmit impulses between sensory and motor neurons. A typical neuron consists of dendrites (fibres that receive stimuli and conduct them inward), a cell body (a nucleated body that receives input from dendrites), and an axon (a fibre that relays the nerve impulse from the cell body outward to its terminals, the synaptic knobs). Both axons and dendrites may be referred to as nerve fibres. Impulses are conducted by neurotransmitter chemicals released by the axon's synaptic knobs across the synapses (junctions between neurons or between a neuron and an effector cell, such as a muscle cell) or, in some cases, pass directly from one neuron to the next. Most neurons are insulated by a myelin sheath formed by cells (Schwann cells) surrounding the axons. Bundles of fibres from neurons held together by connective tissue form nerves
Your brain is made up nerve cells called neurons Neurons are the building blocks of your brain They are constantly communicating with each other The connections among the billions of neurons in all the different parts of your brain is what makes your brain work Your brain is estimated to have 100 billion neurons You can't grow new neurons so take care of the ones that you have
The basic processing element of a neural network Includes weights and bias, a summing junction and an output transfer function Artificial neurons, such as those simulated and trained with this toolbox, are abstractions of biological neurons
Neurons are the nerve cells which make up the central nervous system They consist of a nucleus, a single axon which conveys electrical signals to other neurons and a host of dendrites which deliver incoming signals
any of the impulse-conducting cells that constitute the brain, spinal column, and nerves, consisting of a nucleated cell body with one or more dendrites and a single axon Also called nerve cells, they are essential to the transmission of electrical impulses through the body which is the basis for communication between the body parts and the processing center, the brain Submitted by Jeffrey S Fox, foxjeff1@pilot msu edu neurotransmitter 1 Mediating chemical that carries messages in the form of electrical impulses between most synapses Submitted by Mike Rosol, rosolmic@pilot msu edu
n Any of the conducting cells of the nervous system A typical neuron consists of a cell body, containing the nucleus and the surrounding cytoplasm (perikaryon); several short radiating processes (dendrites); and one long process (the axon), which terminates in twig-like branches (telodendrons) and may have branches (collaterals) projecting along its course
The basic nerve cell of the nervous system A neuron consists of a nucleus within a cell body and one or more processes (extensions) called dendrites and axons
a cell which conducts electric neural impulses from one part of the body to another Neurons are made up of dendrites (branch-like fibers which receive impulses) and axons (fibers which transmit impulses), and communicate with other neurons and effector organs at junctures called synapses
