Mo-DBRS isn’t as sleek as Neuralink’s brain implant. It’s also restricted to people with electrodes already in their brains. So what’s the big deal?
Everything. Those sci-fi dreams of restoring memory, reversing paralysis, battling depression, erasing fear, and solving consciousness? They all depend on capturing and understanding the human brain’s neural code—that is, how do electrical firings turn into memories, emotions, and behavior? Since the beginning of modern neuroscience, this has been done using electrodes implanted into mice or other experimental animals.
Take memory, a brain capability that lays the foundation of who you are.
Until now, memory research has mostly relied on rodents scurrying around mazes looking for tasty treats. Rough translation? Those experiments simulate us finding our cars in a parking lot, and identify the brain waves behind that spatial memory. By recording signals from the mice’s hippocampi, a seahorse-shaped structure buried deep inside the brain, scientists have set up a framework of how our memory works—how a single experience is tied to a time and space, and how a precious memory is linked to our emotions and reinforced.
The obvious problem? Humans aren’t mice.
