Medial geniculate nucleus

The medial geniculate nucleus is a nucleus located in the thalamus that relays auditory information received from the inferior colliculus to the cortex. It is part of the auditory transmission pathway that includes the cochlear nucleus, superior olive nucleus, inferior colliculus, and auditory cortex. The medial geniculate nucleus is directly connected with the primary auditory cortex (A1).From: Dictionary of Biomedical Science [2019], An emergent deep developmental model for auditory learning [2020], Introduction to Non-Invasive EEG-Based Brain–Computer Interfaces for Assistive Technologies [2020]

The primary auditory cortex (A1) is the first cortical region of the auditory pathway, which is directly connected with the medial geniculate nucleus (MGN) of the thalamus. It roughly corresponds with Brodmann’s areas (Figure 1.2) and is located on the temporal lobe. This cortex area is the neural crux of hearing and, in humans, language, and music. The right auditory cortex has long been shown to be more sensitive to tonality, whereas the left auditory cortex has been shown to be more sensitive to minute sequential differences in sound, such as in speech. The auditory cortex is divided into three separate parts: primary, secondary, and tertiary auditory cortexes. These structures are formed concentrically around one another, with the primary cortex in the middle and the tertiary cortex on the outside (Figure 1.5b).

This auditory transmission pathway can be roughly described as follows (Kandel et al., 2012): cochlear cochlear nucleus superior olive nucleus inferior colliculus medial geniculate nucleus auditory cortex, as shown in Figure 6.
