Categorization of regions for correct house trials. (a), left hemisphere regions categorized as accumulator (blue), moment-of-decision (green), or sensory (red) regions. Bright shades indicate consistency in classification with comparable regions in Ploran et al., 2007. Lighter shades indicate inconsistent region function. Numbers in parenthesis designate region index in Tables 2–4. (b), example region (R20, right fusiform gyrus) time series for four RT conditions illustrating a consistent accumulator. (c), another consistent accumulator (R24, left fusiform gyrus). (d), example region (R2, right anterior insula) time series of a consistent moment-of-decision region. (e), another consistent moment-of-decision region (R8, right thalamus). (f), illustration of right hemisphere regions and functional categorization consistency.
