Yeah, but- the PC does things the brain can't do because of speed. In a neuron (at least the peripheral) an impulse travels at about 10 meters/second, and the frequency of impulses to muscles is only about 40 HZ (compare with your house current at 60 HZ and the newest PC chip at 200 MHZ!). The frequency of PD tremor, about 10 HZ, is due I think to the long devious path of the feedback loop. Cheers, Joe J. R.
