  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. Inferior colliculus - Wikipedia

    en.wikipedia.org/wiki/Inferior_colliculus

    The inferior colliculus also receives descending inputs from the auditory cortex and auditory thalamus (or medial geniculate nucleus). [3] The medial geniculate body (MGB) is the output connection from inferior colliculus and the last subcortical way station. The MGB is composed of ventral, dorsal, and medial divisions, which are relatively ...

  4. List of thalamic nuclei - Wikipedia

    en.wikipedia.org/wiki/List_of_thalamic_nuclei

    This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4]) medial nuclear group (medial dorsal nucleus, [5] a.k.a. dorsomedial) parvocellular part [6] (a.k.a. parvicellular part) magnocellular part [7]

  5. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    The medial geniculate nucleus divides into: ventral (relay and relay-inhibitory cells: frequency, intensity, and binaural info topographically relayed), dorsal (broad and complex tuned nuclei: connection to somatosensory info), and; medial (broad, complex, and narrow tuned nuclei: relay intensity and sound duration).

  6. Tonotopy - Wikipedia

    en.wikipedia.org/wiki/Tonotopy

    The lemniscal classical auditory pathway is tonotopically organized and consists of the central nucleus of the inferior colliculus and the ventral medial geniculate body projecting to primary areas in the auditory cortex. The non-primary auditory cortex receives inputs from the extralemniscal non-classical auditory pathway, which shows a ...

  7. Superior colliculus - Wikipedia

    en.wikipedia.org/wiki/Superior_colliculus

    The brachium of superior colliculus (or superior brachium) is a branch that extends laterally from the superior colliculus, and, passing to the thalamus between the pulvinar and the medial geniculate nuclei, is partly continued into an eminence called the lateral geniculate nucleus, and partly into the optic tract. [citation needed]

  9. Internal capsule - Wikipedia

    en.wikipedia.org/wiki/Internal_capsule

    The genu is the bend, or flexure in the V of the internal capsule. It is formed by fibers from the corticobulbar tract.The fibers in this region are named the geniculate fibers that carry upper motor neurons from the motor cortex to cranial nerve nuclei that mainly govern muscle motion of the head and face.
