"There has been one striking and totally unexpected behavioral result: a grave loss of recent memory in those cases in which the medial temporal-lobe resection was so extensive as to involve the major portion of the hippocampal complex bilaterally ... in [H.M.] ... the loss was immediately apparent. After operation this young man could no longer recognize the hospital staff nor find his way to the bathroom, and he seemed to recall nothing of the day-to-day events of his hospital life... However, his early memories were apparently vivid and intact."

The bilateral removal of the hippocampal formation and allied structures caused a severe form of anterograde amnesia.
