Effect of primary visual cortex volume on identification of fragmented pictures. Regressions lines correspond to baseline set, repeated pictures, and novel pictures. Note that lower identification thresholds indicate better performance. Visual cortex volume is associated with repeated but not novel object identification thresholds.
