  2. Neural adaptation - Wikipedia

    en.wikipedia.org/wiki/Neural_adaptation

    Vastly different timescales of adaptation have also been shown to be implemented on the single neuron level, where they can give rise to time-scale free adaptation. [5] At the very extreme of evolutionary timescales, neurons in different parts of retina have been found deploy differing amounts of lateral inhibition to compensate for the high ...

  3. 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.

  4. 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.They are located in the brain and spinal cord and help to receive and conduct impulses.

  5. Neural coding - Wikipedia

    en.wikipedia.org/wiki/Neural_coding

    Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.

  6. Neuron doctrine - Wikipedia

    en.wikipedia.org/wiki/Neuron_doctrine

    Neuron theory is an example of consilience where low level theories are absorbed into higher level theories that explain the base data as part of higher order structure. As a result, the neuron doctrine has multiple elements, each of which were the subject of low level theories, debate, and primary data collection.

  7. Coincidence detection in neurobiology - Wikipedia

    en.wikipedia.org/wiki/Coincidence_detection_in...

    For example (Fig. 1), in a basic neural circuit with two input neurons—A and B—that have excitatory synaptic terminals converging on a single output neuron (C), if each input neuron's EPSP is sub-threshold for an action potential at C, then C cannot fire unless the two inputs from A and B are temporally close.

  8. Grandmother cell - Wikipedia

    en.wikipedia.org/wiki/Grandmother_cell

    The grandmother cell, sometimes called the "Jennifer Aniston neuron", is a hypothetical neuron that represents a complex but specific concept or object. [1] It activates when a person "sees, hears, or otherwise sensibly discriminates" [2] a specific entity, such as their grandmother.

  9. Synapse - Wikipedia

    en.wikipedia.org/wiki/Synapse

    In the nervous system, a synapse [1] is a structure that allows a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or a target effector cell. Synapses can be classified as either chemical or electrical, depending on the mechanism of signal transmission between neurons.
