I am a theoretical neuroscientist. I study models of brain circuits, precisely the sort of models that would be needed to try to reconstruct or emulate a functioning brain from a detailed knowledge of its structure. I don’t in principle see any reason that what I’ve described could not someday, in the very far future, be achieved (though it’s an active field of philosophical debate). But to accomplish this, these future scientists would need to know details of staggering complexity about the brain’s structure, details quite likely far beyond what any method today could preserve in a dead brain.

In that pantheon of illuminatingly broken men and women, Henry stands apart. It is difficult to exaggerate the impact he has had on our understanding of ourselves. Before Brenda Milner collaborated on that first paper about Henry, the prevailing theory of memory held that its functions could not be localized to a single cortical area, that learning was distributed across the brain as a whole. By that theory — built upon the experimental lesioning of the brains of rats — a person’s memory would be affected only in proportion to the amount of brain tissue removed, regardless of which brain structures the tissue was removed from. Milner’s first paper about Henry, along with her previous work, upended this view.

Five years after Milner’s first paper about Henry, she published a second that was almost as revelatory. That paper documented Henry’s gradual improvement over a three-day period on a difficult hand-eye coordination task. His improvement came despite his inability to ever remember his previous attempts at the task, indicating that there are at least two different memory systems in the brain — one responsible for our conscious, episodic memories, the second responsible for task-or-skill related “procedural” memories — and that these two systems seem to rely on entirely distinct parts of the brain. This was another fundamental step forward in our understanding of how memory works. Together, Milner’s two Henry-related revelations can be viewed as the cornerstones of modern memory science.

Corkin: Yeah, but it’s not peer-reviewed, for one thing. That’s important. The stuff that’s published is good stuff. Peer-reviewed. You can believe it. Things that, you know, experiments that might not have been good experiments, there might have been inadequate control groups. ... There are all sorts of things that can go wrong with experiments. Not every experiment is publishable.

Me: But they can still be interpreted by other people. ... Maybe as we continue to understand how the brain works, and how memory works, some of this existing data of H.M.’s could be reilluminated by new theories, by new ideas, by new — it just seems a shame to destroy it. And it also seems — and this would be the darker interpretation of it — it locks in stone your own telling of H.M.’s story.

The researcher who met with S. that day was twenty-seven-year-old Alexander Luria, whose fame as a founder of neuropsychology still lay before him. Luria began reeling off lists of random numbers and words and asking S. to repeat them, which he did, in ever-lengthening series. Even more remarkably, when Luria retested S. more than fifteen years later, he found those numbers and words still preserved in S.’s memory. “I simply had to admit that the capacity of his memory had no distinct limits,” Luria writes in his famous case study of S., “The Mind of a Mnemonist,” published in 1968 in both Russian and English.

The Dress and Yanny/Laurel blow our collective minds because we’re surprised when other people perceive the world differently than we do. And that suggests we’re still attached to the idea that our version of reality is the correct and only one. Nothing could be further from the truth. “It is a fact of neuroscience that everything we experience is a figment of our imagination,”
