Recent technological breakthroughs have made it possible to connect computers directly to the brain using neural implants. These small devices, like the ones used to treat Parkinson’s disease, are surgically inserted into the body and linked to the brain. They can even have new software downloaded directly into them, enabling communication between the brain and external devices.
A major trend in technology is making devices smaller. Currently, neural implants are about the size of a pea. However, experts predict that within the next 20 years, these implants could become as small as a blood cell. This miniaturization could allow for non-invasive delivery methods, such as sending them through the bloodstream, which could transform how we treat serious brain disorders.
Neural implants are becoming more advanced and programmable. Initially, implants for Parkinson’s disease connected to just one spot in the brain. Now, they can connect to multiple areas, expanding from one to two, then four, and potentially hundreds of connections within the neocortex. This increase in connectivity is vital for improving the functionality of these devices.
To advance neural technology, it’s crucial to understand the brain’s design. The human brain’s complexity is encoded in the genome, which holds about 25 million bytes of information related to brain structure. Although this may seem like a small amount of data, it is enough to create a highly complex network of connections, similar to understanding the organization of a vast forest.
With technological progress, we can now observe the brain’s activity in real-time. We can see individual neural connections forming and firing, which helps us understand how thoughts are created. This interaction—where thoughts influence neural connections and vice versa—is key to understanding how the brain functions.
The merging of neuroscience and technology is leading to groundbreaking advancements in understanding and treating brain-related conditions. As we delve deeper into the brain’s complexities and improve neural implants, the potential to enhance human cognition and address neurological disorders becomes increasingly promising.
