I read a paper a long time ago that recorded the brain waves from one person doing a skilled task and then played that recording to an unskilled person as they performed the same task. They replayed the electromagnetic field of the skilled person on the outside of the skull of an unskilled person.

They found that there was an improvement in skill levels in the untrained person. Intriguing.

Does this imply that the brain might communicate with other parts of the brain “asynchronously over a network” through EMF?

That sounds extremely suspicious. If that worked, the applications are obvious and very high value.

If you find the article, please post a link.

But very likely it does not replicate, or is a lot less impressive than tge headline makes it sound.

There's a behavioural neuroscience method you might be interested in:

> Watch Nancy's brain get zapped with transcranial magnetic stimulation. Measuring neural activity (with fMRI, MEG, ERPs, etc) cannot tell you which brain regions or neural responses are necessary for a given aspect of perception or cognition. To find out if a region is necessary, you have to mess with it. One method to do this in humans is transcranial magnetic stimulation (TMS).

Reminds me of this article, where spies abroad all suffer similar strange headaches, impacting their ability to focus.

Perhaps your “hypothetical” bioweapon is already being tested in the field.

Well the CIA seem to think there could be some sort of beam weapon perhaps ultrasonic causing strange neuro injuries with no physical contact.

Havana sickness I think they are calling it if you wanna look up more.
