       | According to the article, ultrasound can measure brain activity
       | and it can influence brain activity in deeper regions of the
       | brain without invasive probes.
       | 
       | This sounds very promising vs electrical techniques.

         | skull and laying the device on the surface of the brain."

       | Another thing I'd like to see - why not both?
       | 
       | There're some very useful AI applications associated with being
       | able to map between different forms of the same data;
       | 
       | With accurate enough processing, a low-end device using the
       | cheaper of any two mechanisms could be used to emulate a more
       | expensive high-end device.
       | 
       | (The way things are, this will most likely be implemented with a
       | subscription model, a proprietary cloud processing engine, and a
       | vendor locked operating system.)
