I recently came across an article, released about a month ago, about a new method for brain stimulation that may be the best method so far.

 

It's called TI Stimulation (at least that's what we call it now)

 

Article

 

It allows deep brain stimulation without stimulating any overlying areas of the brain.

 

It works by getting 2 electric fields (it may be easier to understand if you think of the electric fields as waves) to interefere with each other. Each electric field's frequency is too high to stimulate neurons.

 

When the 2 fields meet, they temporally interefere, to create an 'envelope' area where the frequency of the field is the difference of the frequencies of the original 2 fields.

E.G. Field A has 2.01 kHz frequency. Field B has 2.00 kHz frequency. When they meet a 10Hz (0.01kHz) frequency area is created.

This frequency is low enough to stimulate neurons.

 

A more knowledgeable member than me at Brain Jackers said it was currently the "gold standard"

Another member reviewed the paper with the rest of his lab and said that it was possible to stimulate something as small as 40 microns.

 

Full Paper

 

Funnily enough, this method is much similiar to SAO than other methods such as ECoGs and EEGs.

This is super exciting stuff. I would say I will look into it but before I don't know enough yet to dive into it (gotta learn the foundations first). It reminds me a lot of laser treatment for tumors, in that it combines multiple sources to target an area and ignore the rest. 

 

So this could stimulate the brain, but from what I understand a method such as EEG or ECoGs is still necessary to scan the brain, or am I wrong about that?
