Interhemispheric correlations between portions of visual cortex representing different locations. Bold values indicate correlations between portions of visual cortex representing mirror locations in opposite (left/right) hemifields. All other values indicate the average of two interhemispheric correlations (e.g., L target with R lower field and R target with L lower field). Note that correlations are highest for portions of cortex representing mirror locations. Correlations are computed separately for each subject and separately for trials with leftward and rightward cues, and then averaged across subject and cue. Asterisks indicate regions for which correlations between homologous regions were significantly higher than correlations with any other opposite-hemisphere pairing.
