5) Your cerebral blood flow is being increased - CBF is associated with many forms of mental disorders, including anxiety, depression, attentional problems, behavior disorders and impaired cognitive function. CBF tends to lower as we age often causing cognitive decline. People experiencing depressed mood usually have lower levels of CBF in the left frontal and prefrontal lobes.
Attention and learning ability has been suggested to improve as a result of beta stimulation protocols. Research has shown that beta waves tend to be deficient among those who have learning disabilities and/or attention deficits. Other research with photic stimulation determined that stimulating 14 Hz and alternating it with 22 Hz over several sessions produced significant GPA improvements.

Our everyday, waking brain used for active intelligence operates at approximately 13 hertz, which is in the range of high alpha or low beta frequencies. People who have certain learning disabilities and problems with attention often have low levels of 13 hertz frequency brainwaves in crucial areas of the brain used for sequencing tasks and doing simple math calculations. This is one concrete example of how brainwaves are associated with thinking and behavior. Each identified brainwave frequency has a different effect on a person’s ability to think, act, and feel.
Both brainwave entrainment and neurofeedback deal with brainwaves, but the similarity stops there. Entrainment pushes your whole brain into a pre-determined state, while neurofeedback teaches you how to move specific parts of your brain on your own. It is the differeence between forcing the brain into a given position, and skills building so you can move it there yourself.
