Mu waves, also known as mu rhythms, comb or wicket rhythms, arciform rhythms, or sensorimotor rhythms, are synchronized patterns of electrical activity involving large numbers of neurons, probably of the pyramidal type, in the part of the brain that controls voluntary movement. person suppresses mu wave patterns when he or she performs a motor action or, with practice, when he or she visualizes performing a motor action. This suppression is called desynchronization of the wave because EEG wave forms are caused by large numbers of neurons firing in synchrony.
I should also say something about the Multiple Use Radio Service-MURS. This is an often overlooked service with lots of potential. Unlike the UHF GMRS/FRS (similar to the amateur 70 cm band), MURS is a VHF service, similar to the amateur 2 meter service. MURS radios are permitted up to 2 watts of power, and can use antennas which provide gain. The approximate frequency range of MURS is 150Mhz to 155Mhz on five channels.
