Objective: Optical imaging of intrinsic signals is a new method for a fast and contact free visualization of stimulated eloquent brain areas during neurosurgical interventions. Methods: The intensity of the light reflected by the cortical tissue was measured in 28 patients with lesions around the[for full text, please go to the a.m. URL]
