    English: Complete neuron cell diagram. Neurons (also known as neurones and nerve cells) are electrically excitable cells in the nervous system that process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves. Own work. Image renamed from Image:Complete neuron cell ...

  3. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    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 ...

  4. Synapse - Wikipedia

    en.wikipedia.org/wiki/Synapse

    Synapse. Diagram of a chemical synaptic connection. In the nervous system, a synapse[1] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses from one neuron to another, [2] playing a key role ...

  5. Neural circuit - Wikipedia

    en.wikipedia.org/wiki/Neural_circuit

    In a parallel after-discharge circuit, a neuron inputs to several chains of neurons. Each chain is made up of a different number of neurons but their signals converge onto one output neuron. Each synapse in the circuit acts to delay the signal by about 0.5 msec, so that the more synapses there are, the longer is the delay to the output neuron.

  6. Neurotransmission - Wikipedia

    en.wikipedia.org/wiki/Neurotransmission

    Neurotransmission. The presynaptic neuron (top) releases a neurotransmitter, which activates receptors on the nearby postsynaptic cell (bottom). Neurotransmission (Latin: transmissio "passage, crossing" from transmittere "send, let through") is the process by which signaling molecules called neurotransmitters are released by the axon terminal ...

  7. Interneuron - Wikipedia

    en.wikipedia.org/wiki/Interneuron

    Interneuron. Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons. Interneurons are the central nodes of neural circuits, enabling communication between ...

  8. Neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Neurotransmitter

    Dendrite. Structure of a typical chemical synapse. A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse. The cell receiving the signal, or target cell, may be another neuron, but could also be a gland or muscle cell.

  9. Nervous system network models - Wikipedia

    en.wikipedia.org/wiki/Nervous_system_network_models

    The nervous system consists of networks made up of neurons and synapses connected to and controlling tissues as well as impacting human thoughts and behavior. In modeling neural networks of the nervous system one has to consider many factors. The brain and the neural network should be considered as an integrated and self-contained firmware ...
