SEEING THOUGHTS [ LOOKING INSIDE ( THE AMAZING BRAIN ) ] SEEING THOUGHTS MAGNETOENCEPHALOGRAPHY ( MEG ) also relies on magnetism to examine the brain. In this case, it’s the body’s ambient magnetic fields, not those generated by an external machine, that form the basis of brain imaging. These magnetic fields are extremely weak-perhaps only…
