Come and join us 5th May in Paris!

This is some cool research.

Of the various types of brainwaves we experience on a daily basis, beta waves (12 – 38 cycles per second approximately) are mostly present during activity either physically or mentally. A lack of this frequency of brain activity can lead to low mood and inactivity. And in the case of diseases like Parkinson’s, one of the challenges is that of irregular brain neuronal firing resulting in challenges with walking.

It turns out that as we walk or move our legs there is an increase of Beta brainwaves in the opposite side of the brain.

IE: Beta waves (in the range of 20-30 Hz in this case) shift from side to side of the brain as movement also shifts from side to side in the body. As we know, this happens on opposite sides with the left hemisphere of the brain controlling the right side of the body and vice versa.

This research is being used to experiment with deep brain stimulation of Beta wave frequencies to make walking easier for those with diseases such as Parkinson’s with some promising results. Using audio stimulation cues, this study produced an improvement in the ability of those tested being able to walk with more regular and controlled footsteps.

This positive result raises the further question in my mind as to whether audio visual entrainment could be used to stimulate those Beta waves in a synchronised way on both hemispheres resulting in improved mobility or a reduction in symptoms for these people.

I think that would be an interesting experiment.

Obviously medical advice in such an experiment would be needed particularly as some Parkinson’s medications may cause an increased risk of a negative result such as a seizure.

I do like this type of research though. It shows promise to a lot of people who need help and relief.
