One reason I find neuromorphic chips a very interesting realm of study is
that in order to develop large chips, one must specifically deal with
many of the "system properties" which brain has to deal with (e.g.
power dissipation, connectivity, processing asynchronies, 
computational parts which can vary in response).

Brain obviously performs most of its actions asyncronously.  However,
there is evidence that there are coherencies of oscillations within
visual cortex which may be important for performing neural computation.
An important system level problem is how to organize computations into
synchronous and asynchronous ones.

While many popular artificial neural models deal with settling into a
static attractor, brain shows considerable chaotic and limit-cycle behaviour.
