AI in Brain Research Brain study and neuroscience continue to advance. Two notable clinical research tri- als are being conducted at Neuralink and AI at Meta labs. Reportedly, a second human (as of this writing) has received a Neuralink brain implant, which could lead to a poten- tial milestone in developing brain-computer interface technology. e implant device is one-fih the thickness of a human hair and is designed to sit on top of the brain and detect neuron spikes by detecting signals from indi- vidual neurons inside the brain—a poten- tial advance that could decode higher-qual- ity brain signals. A brain-computer interface, such as a brain implant, allows humans to have direct control of a computer or external device solely using human thoughts. It is a set of tiny electrodes (e.g., platinum) embed- ded in a thin film that conforms to the sur- face of the brain. Each electrode listens to the electrical activity underneath the brain and takes an electrical video in real-time of the thoughts taking place on the brain's surface to record, amplify, digitize, and then trans- mit them using AI to compute the vast num- ber of signals in real-time to aid studies. Separately, the Meta AI lab studies how to read mind and brain activity using a self- supervised learning model that can extract meaning from giant pools of data without human instruction. e goal is to create a "speech decoder" that can directly transform our brain activity (our thoughts) into words. Present and Future How neurons in our brains communicate and explore the nature of cognition is still an enigma and human intellect is still intriguing. Take the stock market as an example. One can use a computerized analysis of market data to detect hidden patterns and write AI algo- rithms to pick stocks 3 . However, at present, no AI model can consistently and reliably pre- dict the stock market. is, in part, is a result of the stock market data being "noisier" than language and other data, making it harder to explain or predict how the market moves 4 . In his book e Transcendent Brain: Spir- ituality in the Age of Science, author Alan Lightman writes, "Some human experiences are simply not reducible to zeros and ones." is reflects the current and future chal- lenges of AI to reach the capacity and capa- bility of the human brain, dubbed Artificial General Intelligence (AGI). 14 SMT007 MAGAZINE I APRIL 2025
