Fig. 8. Comparison of four sections each of two different scans of dolphin OLY. The
left column (A-D) shows a scan without diazepam while the center column shows
sections from a scan with diazepam (E-H). Overall, metabolism is lower in the
left hemisphere. The color bar indicates the relative degree of glucose
metabolism in sections A-H with red indicating maximum. The right hand column
shows oblique axial scans (as indicated in the upper right, section I) of
dolphin MAY's MRI, to which have been registered the difference volumes
between the two scans. In sections J-L, the colored regions correspond to a
reduction in metabolism in the diazepam scan; the color indicates the relative
degree of metabolic reduction with red indicating maximum reductions in
glucose consumption.
