6.6 LORETA Results in Alpha-State Copy

Low Resolution Tomography (LORETA) shows the current density on the brain as extrapolated from EEG measurements. CES activates more of the brain at 8 HZ which is where alpha waves are seen. At 8 hertz, it affects almost the entire brain while other frequencies show little to no activity.


This image displays results for 8 hertz, which is Alpha waves, and shows significant changes after 20 minutes of 0.5 Hz CES. This is how CES is able to induce an Alpha state.

LORETA at 14 Hz

In contrast to the results for 8 Hz, where alpha waves are prominent, at 14 Hz, very little of the brain is being activated.
