What are the most recent theories regarding the generation of brainwaves.
I understand that theories have been put forward regarding certain
thalamic nuclei, which contain certain neurons firing at different rates. 
These neurons project to the cortex and summation of these impulses are
recorded as brainwaves.
But is anymore known in this area?  It all seems rather vague....

Also, it seems accepted that brainwaves can be broken down into their
component sine waves by fourier transform, but what evidence is there that
brainwaves ARE sinusoidal?  What evidence shows that brainwaves cannot
REALLY be sawtooth in some instances, square in others etc.  Are we
creating an artificial construct?

Anyone have any answers?

E-Mail or post on newsgroups please, thanks,
