Abstract: Objective To study the methods and significance of motor and sensory areas mapping by optical intrinsic signal imaging (IOSI) and neuromonitoring (IOM) during the operation on the lesions near the central sulcus. Methods Intraoperative neuromonitoring were firstly used to map the central sulcus and motor cortex in 5 patients with glioma undergoing surgery. Then, intrinsic optical signals imaging were used to locate the postcentral gyrus. According to the results of mapping, microsurgical operation was chosen for the resection of glioma and postoperative functional results were evaluated. Results All the patients acquired accurate location of central sulcus, motor cortex and somatosensory cortex. The enhanced MRI performed within 24 hours postsurgery showed total resection in 5 cases. The motor and somatosensory function of 5 patients returned to normal after 3-12 months. Conclusion Intraoperative location of the somatosensory area and motor area by optical intrinsic signal imaging and neuromonitoring is a reliable and safe method.
