While there are brainwaves occurring in all bands in all states, beta dominates when we are busy with cognitive tasks, interacting with others and going about our daily lives. Some meditators can accentuate this activity. Not much appears to happen here, and yet the brain is active – the brain never ‘switches off’ completely.
Delta (0.1-4Hz)ĭreamless, bodily restorative sleep is characterised by a predominance of brainwaves in this band.
Theta is involved in memory consolidation, and neurofeedback training has shown to improve performance. It is not well understood, and yet we pass through this stage daily between deep sleep and awakening, and vice versa. Hypnosis, light sleep and REM sleep are often linked to this, as are psychic realms. This is the next slower band which is associated with dream-like imagery and deeper relaxation. Generating alpha has become synonymous with being relaxed and aware, a highly desirable state that contrasts with anxiousness on the one hand and drowsiness on the other. More evidence of this is the fact that if we watch a strobe light with the same intensity or brightness at 10Hz, we perceive it to be brighter when set at 10Hz then at say, 7 or 13Hz – the only thing that’s changed is the frequency, not it’s actual brightness. What’s more, we all do this at around the same rate by the time we’re adults, which would seem to promote a sense of synchrony between people. It’s a natural resting rhythm of the brain indicating a relaxed conscious state of awareness, and is particularly strong in meditators.Īlpha is also our brain’s ‘refresh’ rate – we sample the world ten times per second. At around 10 cycles per second, roughly the same for most people, this is particularly prevalent on the back of the head when eyes are closed. This enables us to provide Personalised Brain Training.Īlpha was the first distinct rhythm discovered with EEG technology in the 1920s.

Neurofeedback London-Brighton uses specialised software created by one of the founders of the field of neurofeedback to analyse brainwaves and generate a brain map.Ī qEEG brain map forms the basis for our neurofeedback training plan. The data can then be analysed, for which there are a variety of platforms. We can record brain waves: A 19-sensor cap that is easily set up, attaches to an amplifier that feeds raw EEG data into a laptop. The resulting EEG signal is fed into an amplifier and via software this can be analysed: We can detect rhythms with higher amplitudes in certain bands or ranges. Neurons fire messages through small electrical signals, and these have rhythm! We can measure these electrical vibrations by placing sensors on the scalp (or inside, but attaching them to the surface with a sticky paste that easily washes off will do.). Alpha, beta, theta, gamma, delta… These are all names for bands of frequencies, or cycles per seconds, that the brain produces in its internal communications.
