Task-related modulation in BOLD signal during the low-load condition relative to the baseline of the attention task.
Abstract<p>A. Color on the brain images shows task-related increases and decreases in BOLD signal as revealed by GLM-based analyses. The color bar indicates t values. B1, B2, and B3. Color on the brain images shows regions covered by positive, negative, and neutral ICs, respectively. The color bar indicates number of overlapping ICs.</p
