Certainly the processes of the brain might be influenced this way or that by
random events; but as Tegmark showed the randomness from the environment (i.e.
thermal random motion) is orders of magnitude higher than the intrinsic quantum
randomness.  So you don't need to posit quantum randomness to avoid the
predicament of Buridan's ass.
