The Story of H.M.: The Amnesiac Who Profoundly Changed the Way We Think About Memory

The Story of H.M.: The Amnesiac Who Profoundly Changed the Way We Think About Memory | Fragments of Science | Scoop.it

In our minds, we more or less equate our identities with our memories; our very selves seem the sum total of all we’ve done and felt and seen. That’s why we cling to our memories so hard, even to our detriment sometimes—they seem the only bulwark we have against the erosion of the self. That’s also why disorders that rob us of our memories seem so cruel.

In the excerpt below, I explore one of the most profound cases of amnesia in medical history, H.M., who taught us several important things about how memory works. Perhaps most important, he taught us that different types of memories exist in the brain, and that each type is controlled by different structures. In fact, H.M. so profoundly changed our ideas about memory that it’s hard to remember what things were like before him.

Why Anesthesia Is One of the Greatest Medical Mysteries of Our Time

Why Anesthesia Is One of the Greatest Medical Mysteries of Our Time | Fragments of Science | Scoop.it
Anesthesia was a major medical breakthrough, allowing us to lose consciousness during surgery and other painful procedures. Trouble is, we're not entirely sure how it works. But now we're getting closer to solving its mystery -- and with it, the mystery of consciousness itself.
