Research Abstract	A fMRI experiment demonstrated that the activation of the prefrontal lobe elicited by deceptive behavior in a recognition memory task was increased by the memory materials was emotional. Another fMRI experiment demonstrated that the activation of the hippocampus elicited by the judgment of novelty, was altered depend on the context of the novelty. Furthermore, in a patient group of the left anterior thalamus infarcts, we examined the role of circuitry involving the thalamus and prefrontal cortex in memory by using MRI (diffusion tensor imaging and 3D MRI stereotaxic lesionlocalization) and PET.
