This Memory Prosthesis Boosts Recall in Humans by Roughly 40 Percent
“This one’s for the books: in a jaw-dropping study, a team just turned the human brain from a read-only memory device to a rewritable one.
“What?” you might ask. Of course the brain is rewritable. It’s constantly using electrical and chemical signals to encode our thoughts and memories.
But that’s biology. When it comes to current neurotechnologies, humans haven’t been able to directly encode memories into our own brains. So far, projects like the BRAIN Initiativeor connectomics have only helped us roughly glimpse the complicated neural code buzzing in our heads—that is, to “read” the brain.
No more. In this DARPA-funded study, researchers extracted memory-encoding electrical signals directly from a group of human volunteers while they performed a memory task. When they injected the signals back during recall, it boosted the volunteers’ performance by roughly 37 percent—a shockingly large effect. The results were published this month in the Journal of Neural Engineering…”
