Qi Wang | Writing the Information into the Brain
Columbia Engineering has posted another entry (mirror) in their fascinating series of faculty profiles. Qi Wang is researching methods of directly “writing” information to the brain, thereby enabling direct communication with computers – a field that I have a tremendous interest in, not to mention* my visions therefor. It was a deciding factor in my decision to major in Computer Engineering.
Artificial percepts are just the beginning – we’ll soon be able to “write” data to and read from other parts of the brain, and therewith, record the signals in one person’s brain, and emulate the function of their neurons in another person’s brain. This ability will allow things far beyond artificial percepts, perhaps even “downloadable” skills – for example, recording the activity in Tiger Wood‘s motor cortex when he swings, and later playing back the activity in anyone else’s brain – it’s truly an exciting time.
What I’m referring to is what’ll be like an “app store” (yes, I intend to implement it myself) but for skills! If you consider a cortical microcolumn a functional unit (if you don’t know about the cortical column, see…. like all of modern neuroscience research – which pretty much means Henry Markram), and the neurons therewithin as a black box, an implanted chip can act like a ‘drop in’ part of the brain. It would be plastic, it would seamlessly integrate with surrounding neurons, and most importantly: it would be connected to a computer.
If we record the activity in Tiger Woods’ brain while he swings. then we’d be able to upload them (perhaps with modification, to adjust for body size, strength, etc..) to anyone else’s brain, where a “black-box” implant would emulate the I/O if the equivalent part of Tiger Woods’ brain, and said person would instantly be able to swing like Tiger Woods. Then, we’d set up the equivalent of an “app store”, and sell it for $0.99
Because it’s simply information, charging any more than $0.99 will be immediately circumvented by piracy – just like what happened to the music industry (mirror). It’d also have to be open source, or else nobody will feel comfortable sticking it in their brain.
