EEG waves are not action potentials.

The EEG waves originate from alternating excitatory and inhibitory synaptic potentials that produce sufficient extracellular current flow across the cortex.

There are 27 of these repeats in the yeast Pol II CTD, 32 in the worm Caenorhabditis elegans, 45 in the fly Drosophila, and 52 in humans. 

YSPTSPS repeats in CTD corresponds to the complexity of the genome.
