Was just reading over something I was putting together for an old

Thought you might find it interesting:
"The skin is the easiest target for such stimulation. But, in
principle, any sensory nerves could be triggered. The Controlled
Effects document suggests "it may be possible to create synthetic
imagesÂ…to confuse an individual' s visual sense or, in a similar
manner, confuse his senses of sound, taste, touch, or smell."
In other words, it may be possible to use electromagnetic means to
create overwhelming 'sound' or 'light', or indeed 'intolerable smell'
which would exist only in the brain of the person perceiving them."
I think it was from this location:
