H.M, the man who changed the study of memory
Posted 1 year ago with 11 notes
Henry Gustav Molaison, previously known as H.M., was an American memory disorder patient who had severe epilepsy. Henry underwent a bilateral medial temporal lobectomy, which is the removal of the medial portion of his temporal lobes (particularly the hippocampi, parahippocampal gyrus and amygdalae). His surgery was a success, with a decrease in rates of seizures per day and increase in IQ from 104 to 118. However, Henry soon developed devastating amnesia.
In December 2008, Henry died at the age of 82.
