Category vs. Letter Fluency. Regions with greater activation during the category fluency tasks (C) are shown in red, while regions with greater activation during the letter fluency tasks (L) are shown in blue. Activations are thresholded at p<0.05 (corrected for multiple comparisons). Compared to category fluency, letter fluency resulted in greater activation in left precentral/inferior frontal gyrus (a), bilateral ventral occipito-temporal cortex (b), and bilateral superior parietal cortex (c). Category fluency resulted in greater activation in occipital (visual) cortex, fusiform (b), and left middle frontal gyrus (c). Frontal activation with a greater response to category cues (left middle frontal gyrus, yellow arrow) is located superior and anterior to the frontal activation with a greater response to letter cues (left precentral/inferior frontal gyrus, black arrow).
