Brain-to-brain interface update!

Last year I posted about A Brain-to-Brain Interface for Real-Time Sharing of Sensorimotor Information (I must admit I do love that title) and wondered where these neuroscience developments were going.  I still don’t know the answer to that question but it would appear that we will be getting there much more quickly than I thought.  Researchers in Austria have, for the first time, used stem cells to grow cerebral organoids (mini-brains) in a petri dish.  Meantime researchers at the University of Washington have been playing computer games across the internet.  No surprise there maybe, except that in this case it involved one researcher’s brain and a separate researcher’s trigger finger.  An EEG and a transcranial magnetic stimulation coil meant that when one researcher thought about moving his finger the other researcher’s finger moved.  Whatever next, and where will it all end?
