Medial-lateral organization of primary auditory cortex and the question of sound localization

Pandya made many important contributions to the understanding of the anatomy of the cortical auditory pathways beginning with his publication in 1969. This review focuses on the observation in that article on the transcallosal connections of the primary auditory cortex. The medial part of the cortex has such connections, but the lateral part does not. Pandya and colleagues speculated that this might have something to do with spatial localization of sound. Review of the subsequent literature shows that the primary auditory cortex anatomy is complex, but the original observation is likely correct. However, the physiological speculation was not.

Automated summary

Pandya made important contributions to the understanding of cortical auditory pathways in 1969, particularly in regards to the observations on transcallosal connections of the primary auditory cortex. His speculation on the role of spatial localization of sound was later found to be incorrect, although the original observation remains valid based on subsequent literature review.
