Abstract: A method and device are for generating and displaying a map of a brain operating field, brain tissue areas associated with a stimulated brain function being marked in the map. In the method, during a measurement cycle a stimulation of a brain function is effected and a stimulation image of the brain operating field with the stimulated brain function is recorded, a reference image without the stimulated brain function is recorded, the stimulation image and the reference image are used to generate the map, and the map is displayed on a display. A plurality of cycles are performed. A new map is generated after each cycle following the first cycle. In order to generate the new map, the stimulation and reference images of one or more preceding cycles are used besides the images recorded in the cycle just carried out. At least the new map is displayed after each cycle.

Abstract: A proposed heat-sensitive recording material comprises a substrate, a heat-sensitive recording layer containing color formers and color acceptors, and a protective layer covering this heat-sensitive recording layer. The heat-sensitive recording layer has, as color acceptor, at least 66? percent by weight of 4,4?-dihydroxydiphenyl sulfone based on the total percentage of color acceptors in the heat-sensitive recording layer, and the protective layer has, as binder, at least 60 percent by weight of diacetone-modified polyvinyl alcohol based on the total percentage of binder in the protective layer.

Abstract: A heat-sensitive recording material includes a paper web with recycled fibers and a heat-sensitive recording layer includes color formers and color acceptors. The amount of recycled fiber contained in the paper web is at least 70 percent by weight, and the heat-sensitive recording layer has, as color acceptor, at least 33? percent by weight of N-(p-toluenesulphonyl)-N?-3-(p-toluenesulphonyloxyphenyl)urea in relation to the total content of color acceptors in the heat-sensitive recording layer.
