In the brain, information from all the senses interacts and is integrated in order to create a unified sensory percept. Some percepts appear unimodal, and some, cross modal. Unimodal percepts can be modified by crossmodal interactions given that our brains process multiple streams of sensory information in parallel and promote extensive interactions. TMS can provide valuable insights on the neural substrates associated with multisensory processing in humans. TMS is commonly described as a ‘relatively painless’ method of stimulating the brain noninvasively. However, TMS itself is strong multisensory and this should be considered while interpreting the results. With regard to the crossmodal sensory changes that follow sensory deprivation, these changes can be revealed using a variety of methods including the combination of TMS with neuroimaging.
