  2. Interneuron - Wikipedia

    en.wikipedia.org/wiki/Interneuron

    Relay interneurons have long axons and connect circuits of neurons in one region of the brain with those in other regions. [5] However, interneurons are generally considered to operate mainly within local brain areas. [6] The interaction between interneurons allows the brain to perform complex functions such as learning and decision-making.

  3. Spinal interneuron - Wikipedia

    en.wikipedia.org/wiki/Spinal_interneuron

    The versatile properties of these spinal interneurons cover a wide range of activities. Their functions include the processing of sensory input, the modulation of motor neuron activity, the coordination of activity at different spinal levels, and the relay of sensory or proprioceptive data to the brain.

  4. Spinocerebellar tracts - Wikipedia

    en.wikipedia.org/wiki/Spinocerebellar_tracts

    This is a column of relay neuron cell bodies within the medial gray matter within the spinal cord in layer VII (just beneath the dorsal horn), specifically between T1-L3. These neurons then send axons up the spinal cord , and project ipsilaterally to medial zones of the cerebellum through the inferior cerebellar peduncle .

  5. Low-threshold spikes - Wikipedia

    en.wikipedia.org/wiki/Low-threshold_spikes

    Low-threshold calcium spikes have been described in neurons from a variety of brain nuclei, including the thalamic relay, medial pontine reticular formation, lateral habenula, septum, deep cerebellar nuclei, CA1-CA3 of the hippocampus, association cortex, paraventricular and preoptic nuclei of the hypothalamus, dorsal raphe, globus pallidus ...

  6. Nervous tissue - Wikipedia

    en.wikipedia.org/wiki/Nervous_tissue

    Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.

  7. 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.

  8. Peripheral nervous system - Wikipedia

    en.wikipedia.org/wiki/Peripheral_nervous_system

    The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body. [2] Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins. [3]

  9. Medial geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Medial_geniculate_nucleus

    Thalamocortical relay cells (or principal neurons): The dendritic input to these cells comes from two sets of dendritic trees oriented on opposite poles of the cell. The long axis of the relay cells lie parallel to each other running superior-inferiorly with the dendritic trees of cells within the same iso-frequency band overlapping.
