No. It is very precise.

And choatic systems are completely deterministic: it is the initial
conditions that are the "problem". Heisenberg affects measurements as
well.

The golf ball travelling at 30 mph has a wavelength, via

       E= h v  (de Broglie's equation)

then why ingore (possible) quantum effects at the neuronal level?

Ouch. The Zenner diode, which use quantum tunnellling, is just one
example of QM. And CCD cameras(?)
