The field of neurofeedback training has proceeded largely without
validation. In this article the authors review studies directed at
validating sensory motor rhythm, beta and alpha-theta protocols for
improving attention, memory, and music performance in healthy
participants. Importantly, benefits were demonstrable with cognitive
and neurophysiologic measures that were predicted on the basis of
regression models of learning to enhance sensory motor rhythm and
beta activity. The first evidence of operant control over the alpha-
theta ratio is provided, together with

remarkable improvements in artistic aspects of music performance
equivalent to two class grades in conservatory students.

These are initial steps in providing a much needed scientific basis
to neurofeedback.

++++++++Gruzelier's pet projects seem to be neurofeedback and
the effects of it regarding music and dance. There may
be a built-in bias here. This is interesting to me though.
Maybe there is something to all this. I have a link to
some free software. I can't remember if I posted it or not.

The Healing Power of Neurofeedback

The Revolutionary LENS Technique for Restoring Optimal Brain Function
____________________________________________________________
Excerpt from link:

This book explores a much less invasive but highly effective
technique of restoring brain function: the Low Energy Neurofeedback
System (LENS). Developed by Dr. Len Ochs in 1992, it has had
extraordinary results using weak electromagnetic fields to stimulate
brain-wave activity and restore brain flexibility and function. The
treatment works across a broad spectrum of human activity,
increasing the brain's abilities to adapt to the imbalances caused
by physical trauma or emotional disorders--both on the basic level
and in the more subtle areas of cognitive...

Ecological validity of neurofeedback: modulation of slow wave EEG
enhances musical performance.
Neuroreport. 14(9):1221-1224, July 1, 2003.
Egner, Tobias; Gruzelier, John H
Abstract:
Biofeedback-assisted modulation of electrocortical activity has been
established to have intrinsic clinical benefits and has been shown
to improve cognitive performance in healthy humans. In order to
further investigate the pedagogic relevance of electroencephalograph
(EEG) biofeedback (neurofeedback) for enhancing normal function, a
series of investigations assessed the training's impact on an
ecologically valid real-life behavioural performance measure:

music performance under stressful conditions in conservatoire
students.

In a pilot study, single-blind expert ratings documented
improvements in musical performance in a student group that received
training on attention and relaxation related neurofeedback
protocols, and improvements were highly correlated with learning to
progressively raise theta (5-8 Hz) over alpha (8-11 Hz) band
amplitudes. These findings were replicated in a second experiment
where an alpha/theta training group displayed significant
performance enhancement not found with other neurofeedback training
protocols or in alternative interventions, including the widely
applied Alexander technique.
