	Who says that neural activity can "choose," and what is choosing?  
Looking at the brain as a machine, with input as the axons projecting 
into the brain, and output as the axons projecting out of the brain, if 
you believe that the laws of physics are deterministic (ignoring quantum 
mechanics), then it seems that the brain must be deterministic.  This 
seems to contradict our ideas of consciousness and free-will, but it 
seems to me that you have invoke religous arguments for a soul to get 
free will.
	Of course, the brain has so many neurons, and there is so much going on 
in the brain with neuromodulators and other things we don't understand 
very well, that there is no way that we could predict responses, but it 
seems to me that the brain is ultimately deterministic.
