Abstract

An apparatus is for localizing brain tissue regions connected with a brain function in a brain operating field. The apparatus includes a stimulation apparatus and a localization unit with a camera. The stimulation apparatus is configured to carry out a number of stimulation cycles. Each cycle includes a stimulation phase during which the brain function is stimulated and a rest phase during which there is no stimulation of the brain function. The localization unit records at least one stimulation image with the stimulated brain function and at least one reference image without the stimulated brain function during each stimulation cycle and uses the recorded stimulation and reference images to localize the brain tissue regions connected with the stimulated brain function. The stimulation apparatus is configured to output a feedback signal to the localization unit with at least the start of a stimulation cycle being evident from the feedback signal.
