Added to the three brains, two brains, one brain and brain cells there are brain waves, which play an active part in the reception and retention of information. The four brain waves are:

Beta – This is the brain wave of your conscious mind; it characterises logical thought, analysis and action. You are at your most active and alert. Alpha – This is the brain wave that characterises relaxation and meditation; the state of mind during which you daydream and let your imagination run. It is a state of relaxed alertness that facilitates inspiration, fast assimilation of facts and heightened memory.

Theta – This is associated with the early stages of sleep or deep reverie. This ‘twilight zone’ allows your mind to process the day’s events and information. It is when you may experience flashes of inspiration or creativity. Evidence has been gathered to indicate that Rapid Eye Movement (REM), which occurs during this stage of sleep, helps boost memory. In fact, it provides the opportunity to transfer information from short-term memory to long-term memory. Delta – This brain wave is displayed during deep dreamless sleep.
