Hippocampal activation induced by a memory recall paradigm and detected by high-resolution fMRI: bilateral activation in a healthy volunteer (left, arrows), compared to unilateral activation (left only) in a patient with right-temporal lobe epilepsy (right, arrow; result consistent with memory lateralization as detected by Wada-testing).
