    I suppose in a very general sense it is. All electric phenomena involve the generation of an electromagnetic field and neuronal activity in the brain induces an EM field. Electroencephalograms record EM waves generated by electrical activity in the cerebral cortex of the brain.

    Interestingly some neuroscientists believe that this EM field acts as a feedback mechanism to co-ordinate synchronous firings of neurons in the brain. This notion is attractive as a mechanism to those neuroscientists that favour co-ordinated de-centralised as opposed to localised brain processing functions. :-))

    Here are a few links about magnets being used to help treat people with certain disorders of the brain.
