Here is a discussion going on about this topic-\nhttp://www.halfbakery.com/idea/Weigh_20your_20own_20head\n\nPersonally I like the NMR method idea. I quote -\n" Using NMR you could measure the proton density within each 1mmx1mmx1mm voxel of your head. Then do the same for carbon and calcium and whatever else is in there (can you do this?). Then calculate the mass in each voxel and sum to get the total head mass. NB. This would only work if you don't have any large metal objects in your head, for which decapitation is the preferred method. However this would occur as a by product of the NMR scan anyway because of the magnets so it's a quite general method."

Yes, you must amplify the signals of brain waves in order to be able to display them on a chart.  Was that what you were wanting to know?  What is the question?
