In this project, we use tonotopic mapping at 3 Tesla to investigate whether focal brain lesions alter tonotopic representations in the intact ipsi- and contralesional primary auditory cortex in three patients with hemispheric or cerebellar lesions, without and with auditory complains. We found evidence for tonotopic reorganisations at the level of the primary auditory cortex in cases of brain lesions independently of auditory complains. Overall, these results reflect a certain degree of plasticity within primary auditory cortex in different populations of subjects at different field strengths.
