The kinds of electrical states that are important for decision-making at the anatomical level operate at very different time-scales than the ones that guide behaviour.
Electrical (neural) activity for muscle motions happens on a time-scale of miliseconds.
The time-scale for anatomical changes in anatomical patters is in minutes, hours, days in some cases. These are stable patterns. Different set of frequencies.
Cells are very good at distinguishing different types of electrical signals (multi-scale problem solving that does not interfere with eachother).
The interventions they need to make are also incredibly brief, because these electrical circuits have stable attractor, they maintain state once you knock them into it.Changing these anatomical patterns is done by adding or removing new ion channels or similar through either genetic interventions? or chemical cocktails.
Plants do very similar things with electrical signaling that michael levin talks about, even though they share different origins of multi-cellularity.
They both discovered this independently, because even the bacterial ancestors propagated brain-like postassium waves.
