In reality, the brain IS a magnetic field ... part of a biochemical electromagnetic circuit ... so in truth it doesn't need another magnetic field to stimulate it ... but, that truth appears to be missed in all the glory of this 'new discovery';
UK Guardian, says: A magnetic field can stimulate the brain and promote the growth of new nerve cells, scientists have found, raising the possibility of treating conditions linked to neuron death such as Alzheimer's disease, and perhaps one day of enhancing humans' memory capacity.
