 CommentaryThe neural systems underlying retrieval of images from long-term memory are complex and varied, depending on the nature of the stimulus and the timeframe of image acquisition. Different parts of the brain are involved, according to whether the image is familiar (prefrontal, lateral temporal, and mesial temporal [hippocampal and parahippocampal regions]) or not (frontal and parietal regions). It is unclear to me why so many frontal regions were activated by this inexplicably unfamiliar ampullary image. I just hope the likeness shown here will be incorporated into neural retrieval systems in a widespread fashion so that unnecessary surgical or endoscopic procedures can be avoided.Lawrence J.
