[FRIAM] Unpleasant dreams

I'll try again:

In particular, see Figure 2:

"A Cortical distribution of statistical differences in delta (A) and beta (B) power (t values, Wald statistics) for CE vs NE. Left column: 20 s of sleep preceding movement onset (CE: n = 32 episodes from 14 participants, NE: n = 11 episodes from 7 participants). Right column: from 4 to 20 s after movement onset (CE: n = 31 episodes from 14 participants, NE: n = 10 episodes from 7 participants). Only voxels with significant effects appear colored. LL left lateral, RL right lateral, LM left medial, RM right medial view."

It's not that EEG is more or less important than, say, eye movement or fMRI or whatever. But many of these methods argue against the naive combativeness of Nick's rhetoric.
