  • In Figure 2, the fastest 75% of the abstract trials (25, 50, and 75 quartiles) are matched based on the mean response times and directly compared against the slowest 75% of the sensory trials (50, 75, and 100% quartiles). For the prefrontal regions of interest, percentage signal change from the pseudoword condition is presented. SEM for each measure is given in parentheses.
