The Expanding Mind

By Pete Estep | Seed Magazine

"Scarcely a decade has passed since scientists painstakingly sequenced the first bacterial genome, yet today automated human genome sequencing is becoming routine, heralding a new era of medicine. Replacement tissues and even organs can now be grown from a patient’s own cells and used without risk of immune rejection. Genetic therapies for a plethora of debilitating conditions are on the horizon; brain and body imaging technologies allow early discovery of potentially harmful pathologies. But as these developments have unfolded, another area of research has simultaneously matured to rival them in its dramatic potential to help people. It’s called neuroengineering.

My colleagues and I have expected these events for years, but we are still awed by the results; some things are so powerful that, even if you know they are coming, they remain breathtaking when they actually arrive. Watching a person move a robotic limb or control the functions of a computer, through thought alone, we have little choice but to stare in amazement. These breakthroughs were made possible by prototype brain-computer interfaces (BCIs), which allow direct communication between the brain and external devices."
