Brainwave Entrainment is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep), usually attempted with the use of specialized software. It purportedly depends upon a "frequency following" response on the assumption that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. [citation needed] Such a stimulus is often aural, as in the case of binaural or monaural beats and isochronic tones, or else visual, as with a dreamachine, a combination of the two with a mind machine, or even electromagnetic radiation.
Hemispheric Synchronization, a potential and generally desired result of brainwave entrainment, refers to a state when the brainwave pattern of the right and left hemispheres become alike. A person with similar activity in both hemispheres is alleged[by whom?] History[edit] Notes[edit] Boost Your Brain’s Power With a 9-Volt Battery and Some Wet Sponges. It seems, with the help of a 9-volt battery, wire, crocodile clips, and wet sponges, you can increase your brain’s performance and, more importantly, return your brain to its younger, more malleable and learning-receptive state. The technique, which is lumbered with the fantastic and slightly terrifying name of transcranial direct-current stimulation (tDCS), is similar to deep brain stimulation (DBS), but it doesn’t involve complex neurosurgery.
TCDS runs a very small current — just 2 milliamps — into brain tissue just beneath your scalp; it’s non-invasive, and seemingly quite safe. By pumping electrons into the brain, neurons move a few millivolts towards ‘depolarization’, which makes them more sensitive, and thus reducing the time it takes signals to travel across your nervous system. More importantly, though, this technique increases the plasticity of brain tissue, leaving it in a kind of ‘wet clay’ state after the electrical current has been removed. Read more at Nature.
