Before revision:  Structures of cerebral tissues of the anterior cingulate cortex were visualized with synchrotron radiation nanotomography. Tissue constituents observed in the three-dimensional images were traced to build Cartesian coordinate models of neurons. The obtained Cartesian coordinates were used for calculating curvature and torsion of neurites. The geometric analyses indicated thatthe curvature of neurites is significantly different between schizophrenia and control cases. The mean curvature of distal neurites of the schizophrenia cases was approximately 1.5 times higher than that of the controls .
After revision:  The analysis revealed that: (1) neuronal structures vary between individuals, (2) the mean curvature of distal neurites of the schizophrenia cases was approximately 1.5 times higher than that of the controls .
