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. 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. Neuroscience: Brain buzz. Life Hacks.
