Why Doesn't An Electro Magnetic Pulse(EMP) Affect The Human Brain?

The electromagnetic radiation arising from a nuclear explosion caused by recoil electrons and photoelectrons from photons dispersed in the materials of the nuclear device or in a surrounding medium is known as Electro Magnetic Pulse or EMP. The resulting electro-magnetic fields can team up with electrical or electronic system to produces voltage surges and electric shocks.

A solitary high-altitude nuclear burst of 10 or more megatons at the geographic center of North America has the strength to cripple virtually every type of unprotected electronic circuitry in a matter of 5 nanoseconds.  Essential weapon control systems can also be damaged irreparably.  The research into the electromagnetic weapons has been under way since the 40s. It is possible to develop a weapon that can produce electromagnetic radiation capable of killing people 5 or 10 miles away from sources. The EMP can certainly affect human brain especially if the wavelength is less than 2 meters.

Only an extremely high field pulse would have a noticeable result on the cells of the brain.

Considering the baseline or the continuous field power that is existent across the membranes of every living cell when they are presently sustaining a resisting potential to be negative 60 mV, the difference between the voltage would drop considerably throughout the whole hydrocarbon layer in the lipid bilayer that measures 3 nm in width. This would imply that the power of the resting field sustained through the cell membrane would be 20 MV/m. EMP pulses would have to be almost of this level across the cell membrane to affect living cells.

However, this does not rule out the possibility that someone could design an EMP generator that can attain these field strengths.
