New result!
A ubiquitous cortical signature: Beta is stronger in deep layers, gamma is stronger in superficial layers. So robust you can find layer 4 by the crossover point, everywhere.

@ekmiller Fascinating! Do you think by using MEG source localization one could extend this idea non-invasively to humans? (of course with the baggage of assumptions of the source localization method) Or do you think the motif could vary too much given the limited spatial resolution of MEG?

I think so. It would be good to know because the relationship between EEG/MEG and activity in the brain is not necessarily straightforward:

@ekmiller Given that MRI can only resolve upper, central and deep layers, the question arises whether MEG, superimposed on MRI scans could resolve layer 4 by using this principle and measuring gamma and beta.

@dickretired
Only one way to find out.

@ekmiller very interesting.
