Persinger can put signal into the temporal lobe by magnetic
field and cause people to experience live hallucinations. I
wonder if someone has experimented on ejecting images
into the visual cortex so you can see stuff superimposed
on your visual field that is indistinguisable from reality
such that you can't tell them apart. They just have to figure
out the right signal strength and frequency. Rodolfo Llinas said
40 Hz bind the brain, so if we can use a 40 hertz magnetic
field tuned to the neurons strength then we can maybe inject
any live feed into the brain. I wonder what is the latest
in this field.
