Frequently asked questions

“Will the EEG pick up on how much I partied last night?

No, not unless you are comatose from that event, in which case you might want to book for another day.

“Do the electrodes put anything into me, like an electric shock or subtle information?”

Absolutely not. The headbands we use have dry cell electrodes so we don’t even use conductor paste with these. They simply measure electrical activity in your brain.

If you are alive, you have electrical activity which jumps from nerve cell to nerve cell. The EEG translates that into visible waves. The waves you see strongest on the screen are the winning waves, the most active ones at that moment in your brain.

“Will you be able to see my thoughts? Will you be able to see if I draw a “blank”?

Absolutely not. The electrodes pick up how excited or calm your brain activity is, and even that changes from second to second.

“What  are these Hz, like what do the various mind states indicate?”

The thoughts that fill our heads are carried by tiny electrical currents which spark between the neurons in our brains in waves of energy. The currents are sometimes fast and sometimes slow depending on how the energy is oscillating. By placing electrodes on the head, those waves of energy can be measured.

These days, that energy can be measured by a portable electroencephalogram (EEG) device.

Brainwaves are numerous and varied, measured by their height (their amplitude) and their speed (cycles per second, Hz) Their Hz is the number of  times per second that electrical level waves.

Here is a list of frequencies by Hz ranges:

Frequency band


Brain states

Beta (β)

12–35  Hz

Anxiety dominant, active, external attention

Alpha (α)

8–12 Hz

Very relaxed, passive attention

Theta (θ)

4–8 Hz

Deeply relaxed, inward focused

Delta (δ)

0.5–4 Hz


Everyone experiences all of these waves pretty much all the time, but the dominant ones at any given moment are the ones available to be measured by surface electroencephalogram (EEG) machinery, such as the headbands or even the clinical electrodes with an encoder.

The best brainwaves for connection are in the Alpha range (same wavelengths best for meditating), but connections can occur when and wherever the pair matches.

“How many sessions will we need to be able to do MIND PHASING at will?”

Everyone improves in ONE session. Sometimes only ONE session is required to walk away with a life-long get-along-better tool. Clients who want to get better at getting into an Alpha state for their own meditation can do so with practice.
