Brain areas showing a linear decrease in activity as a function of word recognition, by using fixed-effects analyses. Linear changes in brain activation are found in prefrontal, thalamus, anterior cingulate cortex, and parietal regions. Z-values of 3.0–5.1 correspond with changing brain activation colors from red to yellow, respectively. The right side of the brain on the image corresponds with the left hemisphere, and vice versa.
