That frequencies and amplitudes are basically different expressions of rates and degrees.

Time and temperature.

It is just that as mobile organisms, this sequential process of perception is the focus of our sense of being. The point of clarity of our emotions.

E.O. Wilson described the insect brain as a thermostat, essentially responding to the energies of the environment.

Yet it has also been shown that ants can count, as a function of navigation;

So they also have some essential sequence function.

In the classic left/right hemisphere of the brain, it would seem the right, emotional side is the thermostat/barometer, while the left logical side is the clock/ruler. One sensing amplitudes of the energies and the other calibrating the patterns expressed.
