WebAlso, the early somatosensory cortical responses are enhanced in trumpet players compared to non-musicians when tactile (lip stimulation) and auditory (trumpet tones) cues are presented simultaneously (Schulz et al., 2003), thus providing evidence of cross-modal reorganization associated with multimodal sensorimotor training. WebIntroduction. At first blush, the notion of auditory responses in non-auditory, sensory cortices seems counterintuitive. In areas dominated by vision or touch, it would seem unlikely that the brain would direct resources toward extracting information from anything but those specific modalities, and that little insight into the organization and function of … crystal seachrist
