What is the nature wave frequency for the human brain?

Question

I want to know what the range of eletromagnetic waves in the brain are? Can these waves be tranmitted and interefere or brainwash or control or manipulate the human brain?

Answer 1

Electroencephalography  is the means of measuring it.

A typical adult human EEG signal is about 10µV to 100 µV in amplitude when measured from the scalp [3] and is about 10–20 mV when measured from subdural electrodes.

There is also an Alpha state and Beta state of brain activity
