How does the brain determine states of consciousness?
It is the combination of Beta, Theta, Alpha and Delta brainwave signals that determines your state of consciousness at any given time. Though all of these occur simultaneously and emanate from different brain locations, one of these may be more predominant depending on your brain state. By monitoring your brainwaves as you meditate you can learn to attain deeper relaxation even as you sustain states of heightened awareness. You can achieve “awakened mind” brain-wave patterns through applied practice.
