Method and apparatus for localizing areas of brain tissue associated with a brain function

摘要

A device is provided for localizing brain tissue areas (15) connected to a brain function in a brain operation field (17). The device comprises a stimulation device (1) and a localization unit (3, 7) with a camera (3), the stimulation device (1) being designed to carry out a number of stimulation cycles, the stimulation cycles each having a stimulation phase during which the Brain function is stimulated, and a rest phase during which no stimulation of the brain function takes place, and - the localization unit (3, 7) is designed with the aid of the camera (3), at least one stimulation image with the stimulated brain function and at least for each stimulation cycle to record a reference image without the stimulated brain function and to use the recorded stimulation and reference images to localize those brain tissue areas (15) that are connected to the stimulated brain function. The stimulation device (1) is designed to output a feedback signal, from which it can at least be seen when a stimulation cycle begins, to the localization unit (3, 7).
