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 ...
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 ...
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 ...
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).
medial pulvinar nucleus [28] inferior pulvinar nucleus [29] lateral posterior nucleus [30] belongs to pulvinar; lateral dorsal nucleus [31] (a.k.a. dorsal superficial nucleus) ventral nuclear group [32] ventral anterior nucleus [33] ventral lateral nucleus [34] ventral medial [35] (a.k.a. medial part of ventral lateral nucleus) anterior ventral ...
This has led to the assumption that they may be involved in general functions such as alerting. [1] However, anatomical connections might suggest more specific functions, with the paraventricular and paratenial nuclei involved in viscero-limbic functions, and the reuniens and rhomboid nuclei involved in multimodal sensory processing.
The acoustic radiations or auditory radiations are structures found in the brain, in the ventral cochlear pathway, a part of the auditory system. [1] [2] Acoustic radiation arising in the medial geniculate nucleus and end in primary auditory cortex (transverse temporal gyri).
