Fig.: DiI-labelled neuron from human prefrontal cortex
The specimen with the DiI postmortem tracing was kindly provided by Dr. D. Senitz, Univ. of Würzburg, Germany. About 100 optical sections were scanned through the tissue with a confocal laser scanning microscope (Leica Microsystems, Bensheim). Subsequently, isosurface volume rendering was performed using a 3D image software (AMIRA, Indeed, Berlin).
