The abstract reads:
"Contemporary neuroscience suggests the existence of fundamental algorithms by which all sensory transduction is translated into an intrinsic, brain-specific code. Direct stimulation of these codes within the human temporal or limbic cortices by applied electromagnetic patterns may require energy levels which are within the range of both geomagnetic activity and contemporary communication networks. A process which is coupled to the narrow band of brain temperature could allow all normal human brains to be. affected by a subharmonic whose frequency range at about 10 Hz would only vary by 0. 1 Hz."
Persinger's the investigator who uses a magnetic helmet to induce subjects to feel the presence of somebody else in the room with them (when there's nobody there), right?
