Significance of dynamic gray matter loss in normal adolescents and in
schizophrenia. Highly significant progressive loss occurs in
schizophrenia in parietal, motor, supplementary motor, and superior
frontal cortices. Broad regions of temporal cortex, including the
superior temporal gyrus, experience severe gray matter attrition. By
comparison of the average rates of loss in disease (middle column) with
the loss pattern in normal adolescents (first column), the normal
variability in these changes can also be taken into account, and the
significance of disease-specific change can be established (last
column).
