The medial geniculate body of the thalamus receives input from a variety of sources, both auditory and non-auditory. The ventral division (MGv), however, appears to be a purely auditory center, that is, it receives from lower (and higher) centers which are primarily involved in encoding auditory stimuli. It has some of the characteristics of auditory cortex, e.g., layering of neurons and EE/EI bands, but has a much simpler architecture. The MGv plays a central role in analyzing auditory stimuli. A wealth of data is available now on its anatomy, connectivity and responses. A detailed computational model of the ventral division of the cat medial geniculate body has been constructed. This model is being compared to physiological recordings for validation purposes, and should prove useful tool for testing theories of auditory sensory representation and functioning.
