FIGURE 1. Axial tomographic brain slices were displayed in original linear (or inverse linear) gray scale (A), according to a statistically parameterized scale (B), and by an asymmetry parameterized scale (C), as described in the text. Numerically labeled color bars were displayed adjacent to the parameterized scales (D). Scan interpreter could specify the proportion of cortex (x%) for which maximal asymmetry was to be quantified as well as certain display features that would not directly affect quantification, using interactive slider controls (E).
