Zusammenfassung

Impedance measurements in intact cerebral structures of human cadaver brains were performed to analyze the potential of this method to verify the position of the needle during a stereotactic intervention. Experiment 1: Impedance measurements were performed at 24 selected points in human cadaver brains. The points were labeled using DiI. The texture of the nerve fibers was visualized using confocal laser scanning microscopy, which allowed classification of distinct anatomical regions in the white and gray matter according to their fiber structure. These regions displayed characteristic differences in impedances a…
