Scientists Successfully Create Brain Interface That Improves Memory
Cognitive-boosting prosthetics are quickly becoming a reality as doctors are seeing success with a neural interface that improves memory function by stimulating electrodes implanted in the brain.
This “closed-loop hippocampal neural prosthesis” has moved from testing on rodents, to actual human application with positive results. The device works by sending electrical signals from an apparatus outside the body to electrodes internally connected to the hippocampus, a seahorse-shaped part of the brain that plays a major role in memory.
Researchers involved in the program describe their approach as aiming to use patient’s own neural codes for memory through a closed-loop system in which electrical signals are exchanged instantaneously.
Patients using the system showed a 37 percent improvement in short term memory tests. Scientists were even more surprised to find that long-term memory of 30 to 60 minute intervals had also improved by a similar 35 percent.
But these electrical zaps weren’t just random stimulation. Researchers carefully recorded where and when specific regions of the patients’ brains reacted when performing tasks involving the use of memory, and carefully tailored electrical pulses to induce a similar response.
The team originally tested their method on brain tissue, before moving on to rodents, and then monkeys. Now, with their success in humans, they will continue to develop the technology in hopes of someday having a fully implantable apparatus to boost cognitive function.
One of the members of the team touted memory as being part and parcel of one’s personality. Our collection of memories in life certainly play an important role in individuality allowing us to recall experiences that shape our lives.
The team hopes this technology could one day help restore memory function to those affected by drugs, disease, and brain injury.
Their success in memory enhancement comes at a time when interest in cognitive boosting technology is piquing. A number of scientists have been working on mapping out the brains’ neurological connections in hope of developing computer-brain interfaces for superhuman neurological function.
Elon Musk is currently invested in a project called Neuralink, a neural mesh laid over the brain, merging AI with human cognition. Musk says the concept would ideally improve the speed of connection between the brain and one’s digital self, focusing particularly on output.
With the recent success of this closed-loop hippocampal prosthesis, it wouldn’t be too far-fetched to expect some investment from Silicon Valley in the future.

If the Universe is a Simulation, Can We Hack It?
In 2003, Nick Bostrom published a paper proposing three scenarios he says he believes are likely to be true about our reality. One of those possibilities is that we are living in a computer simulation, a theory gaining increasing attention in our era of prevailing tech fascination. But if the universe is a simulation, can it be hacked?
Is the Universe a Computer Simulation?
We’ve heard from a number of scientists and thought leaders, including Elon Musk, it’s likely we’re living in a computer-simulated reality. Musk said he believes there’s a one-in-billions chance we’re living in “base reality,” or a non-simulated, completely organic existence.
It’s also becoming more apparent that mathematics is the language of nature — a universal dialectical that can be used to describe everything, from the inconceivably large to the infinitesimally small. As we continue to acquire more insight on this reality, it appears we may be living in what appears to be a physical construct that might actually be generated from code.
