Sidney Perkowitz delves into the cutting-edge work being done to make brain–computer interfaces safer, more durable and widely available

The human brain is an astounding and complex piece of machinery. With more than 80 billion neurons in the human cerebral cortex, each with a thousand synapses, our brains process some 100 megabits of information per second. Imagine then, attempting to measure, extract and interpret all the signals in our brain in real time, at the speed of thought. […]
