  2. Medial geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Medial_geniculate_nucleus

    There are two main cell types in the ventral subnucleus of the medial geniculate body (VMGN): 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 ...

  3. Trisynaptic circuit - Wikipedia

    en.wikipedia.org/wiki/Trisynaptic_circuit

    The trisynaptic circuit or trisynaptic loop is a relay of synaptic transmission in the hippocampus. The trisynaptic circuit is a neural circuit in the hippocampus, which is made up of three major cell groups: granule cells in the dentate gyrus, pyramidal neurons in CA3, and pyramidal neurons in CA1. The hippocampal relay involves three main ...

  4. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    The soma is the body of the neuron. As it contains the nucleus, most protein synthesis occurs here. The nucleus can range from 3 to 18 micrometers in diameter. [8] The dendrites of a neuron are cellular extensions with many branches. This overall shape and structure are referred to metaphorically as a dendritic tree.

  5. Neurotransmission - Wikipedia

    en.wikipedia.org/wiki/Neurotransmission

    Neurotransmission implies both a convergence and a divergence of information. First one neuron is influenced by many others, resulting in a convergence of input. When the neuron fires, the signal is sent to many other neurons, resulting in a divergence of output. Many other neurons are influenced by this neuron. [citation needed]

  6. 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.

  7. Median preoptic nucleus - Wikipedia

    en.wikipedia.org/wiki/Median_preoptic_nucleus

    The median preoptic nucleus is located in the preoptic area of the hypothalamus.Forming a critical part of the anteroventral third ventricle and the midline of the lamina terminalis, the median preoptic nucleus occupies an anatomical position that allows it to play an important role in many aspects of homeostatic regulation.

  8. Axon reflex - Wikipedia

    en.wikipedia.org/wiki/Axon_reflex

    The axon reflex [1] (or the flare response) [2] is the response stimulated by peripheral nerves of the body that travels away from the nerve cell body and branches to stimulate target organs. Reflexes are single reactions that respond to a stimulus making up the building blocks of the overall signaling in the body's nervous system.

  9. Proprioception and motor control - Wikipedia

    en.wikipedia.org/wiki/Proprioception_and_Motor...

    Proprioception refers to the sensory information relayed from muscles, tendons, and skin that allows for the perception of the body in space. This feedback allows for more fine control of movement. In the brain, proprioceptive integration occurs in the somatosensory cortex, and motor commands are generated in the motor cortex.
