Fisher Wallace says it stimulates your brain into producing more endorphins, serotonin for mood balance and melatonin for healthy sleep, while also lowering the stress hormone cortisol, reports Engadget.

Kortex works by stimulating your brain using low doses (max of 2mA) of pulsed alternating currents. According to the Indiegogo campaign page Fisher Wallace set up for the product, some people might feel “mild tingling” at the electrode sites, but most don’t.
