Typical current ways of measuring brainwaves have limitations.
Electrodes on the outside of the skull cannot accurately measure past the ‘noise’ of the brain surface to measure what goes on deep inside the brain’
Electrodes implanted in the brain itself require surgical procedures, risk damage, and are usually only temporary as they are not something that could be worn while a normal standard of life is continued.
Latest technology in micro-wires and silicone chips now allow for an electrode to be 15 times thinner than a hair!
That is so thin that it can be inserted deep into the brain without significant damage and 100’s of thousands can be used to get pin point accuracy.
Can’t say I would want that many wires in my brain, lol, but the idea that for people with neurological challenges there is a solution that could monitor, diagnose and instantly deliver a stimulus to just where it is needed to auto-correct neurological disorders is promising.
And the ability to combine this with other research like using double light spectrometry (not in this article) which can literally measure electrical signals in the brain at 1,000 times per second.., means that scientists and medical practitioners can literally now watch a single neuron fire, and follow it along it’s path to where it reacts with another neuron and which neurons it ignores on the way.
By doing this they can isolate (word of the year here in 2020, haha) a signal that will ONLY react with a specific brain neuron and not effect any others.
Very clever and potentially game changing for neuroscience.
