The user is provided with goggles which emit light over the closed eyes and headphones which produce stereo sound. The light and sound is pulsed at the desired target frequency, facilitating entrainment. AquaThought has found light and sound entrainment to be a powerful methodology of altering dominate brainwave frequency. Light and sound stimulation, when combined with other entrainment modalities, is a valuable resource for neurological wellness research. Electrical and Electromagnetic - These modalities of neurological stimulation provide electrical current directly to the brain.
Electrical stimulation is delivered through electrodes attached to various areas of the scalp.
Electromagnetic stimulation creates currents inside the dura mater and deeper neurological structures through magnetic field induction. Both methods result in entrainment by electrical stimulation of neurological circuitry at a target frequency. Electrical stimulation methods result in dramatic dominate brainwave frequency modification. AquaThought's current research involves various forms of electrical stimulation signals aimed at specific locations within brain. AquaThought's Montage Amplifier is a device which records brainwaves and employs them as the output stimulation in a magnetic induction helmet.
