Mu waves, which are also named as wicket rhythm or comb are generally electromagnetic oscillations which are around the frequency range of eight to thirteen hertz and is present in bursts of nine to eleven hertz. The Mu wave patterns generally happen in coherent and synchronous electrical action of huge groups of neurons present in human brain. Such wave activity will be related to motor cortex (central scalp) and is reduced with movement or intentions to move and while others observe such performing actions. The researchers like V.S Ramachanrand state that Electroencephalogram oscillations present in Mu wave indicate the mirror neuron activity. Based on contradicting proof obtained by experiments on mu-wave suppression, Patricia Churchland has mentioned that suppression of mu-wave will not be utilized as proper index to measure the concert of mirror neuron systems. Mu waves are generally detected through MEG (Magnetoencephalography) or EEG (Electroencephalography). The mu waves are variants of alpha waves.

History

The study of mu waves was done initially during 1930s and they are also called as wicket rhythm since the rounded waves taken through Electroencephalography reflected the croquet wickets. During 1950s, the Gian Emilio Chatrian indicated that mu wave amplitude could be reduced through physical movements. The studies later indicated that the intention to move or various other mental or visual tasks could reduce the amplitude of mu waves.

Neurofeedback

The Neuro feedback training EEG is a method which enable person to alter their brain waves through feedback about their present state. The research has stated that the dysfunctional mirror system neuron might indicate the pathology noted in ASD – autism spectrum disorders. The mu waves and mirror neurons might have a major role in capacity to appreciate and emulate the behaviour of others. The results of initial research to enhance the activity of mu waves through bio feedback, for treating autism have got good results so far.
