Texture, a fundamental object attribute, is perceived through multisensory information including touch and auditory cues. Coherent perceptions may rely on shared texture representations across different senses in the brain. To test this hypothesis, we delivered haptic textures coupled with a sound synthesizer to generate real-time textural sounds....

Background Studying brain processes underlying tactile perception induced by natural-like stimulation is challenging yet crucial to closely match real-world situations. New Method We developed a computer-controlled pneumatic device that allows the delivery of complex airflow patterns on subject’s body, through a MR-compatible system fixed on an in...

Motion perception is facilitated by the interplay of various sensory channels. In rodents, the cortical areas involved in multisensory motion coding remain to be identified. Using voltage-sensitive-dye imaging, we revealed a visuo-tactile convergent region that anatomically corresponds to the associative parietal cortex (APC). Single unit responses...

Any sensory stimulus evokes a propagating wave of activity in the corresponding sensory cortex that exceeds its topographical boundaries within the primary sensory map. Hama and colleagues provided a first study, in the tactile modality, of the interactions between two successively evoked waves. We argue that the difficulty in finding a simple rule...
