I stated ealier that there is no agreement on how to do volumetry on the amygdala--inaccuracy of borders and variations among the population. She did use the MRI as a diagnostic tool. She testified that his amygdala, hippocampus and another areas were smaller than normal and this supported her diagnosis of schizophrenia. Also a drop in IQ from 123 to 117 is insignificant and could be due to inherent error in the test. If he went from 123 to 100 that could be significant.
