## Abstract Two magnetic resonance imaging techniques, BOLD (blood oxygenation level dependent) and EPISTAR (echo‐planar imaging and signal targeting with alternating radio‐frequency), were compared for functional brain imaging. Ten volunteers were imaged performing a sequential finger to thumb opp
