Figure 7

Region-of-interest (ROI) analysis of activation differences between HiRe and LoRe trials in monkey STG. The box plots show mean signal magnitudes (two monkeys) in each anatomically-defined STG ROI. To remove outliers, the central 85% of values were included in each case leaving 15–30 runs for M1 and 15–30 runs for M2, depending on the response measure in question. Asterisks indicate significant pair-wise tests comparing signal magnitude between HiRe and LoRe trials in each ROI (permutation-based significance testing using Welch’s v tests, two-sided, 10 000 permutations, FWER corrected across all pair-wise comparisons, *P < 0.05, **P < 0.01 and ***P < 0.001). Note that each test compared activation across HiRe and LoRe trials with identical auditory stimuli and motor responses. The inserts at top show the location of the ROIs. The difference between HiRe and LoRe trials was significant only during the hit and early response trials and the effects were most consistent in the posterior and middle parts of STG.
