Kirsch and colleagues report the first human lesion study on the perception of C-tactile touch in right hemisphere stroke patients (N = 59). The results show that lesions in the right posterior and anterior insula reduce tactile, contralateral and ipsilateral pleasantness sensitivity, respectively. These findings provide important insight into the Read more…
