The BigBrain is the brain of a 65yo man with no neurological or psychiatric diseases in clinical records at time of death. The brain was embedded in parafin and sectionned in 7404 coronal histological sections (20 microns), stained for cell bodies. The bigbrain is the digitized reconstruction of the hi-res histological sections (20 microns isotropic). The BigBrain dataset is the result of a collaborative effort between the teams of Dr. Katrin Amunts and Dr. Karl Zilles (Forschungszentrum Jülich) and Dr. Alan Evans (Montreal Neurological Institute).
