Complete Guide To Brainwaves

The brain is an electrochemical organ. Millions of electrical pulses pass between neurons when we work, exercise, relax or sleep. Electrical activity of the brain can be observed as brainwaves: the synchronized firings of populations of neurons. The speed of brainwaves is related to the level of activity. Below, we will briefly cover each of the five frequency bandwidths, starting with the slow delta waves.
