Abstract:

   Despite recent progress in neural networks, humans still can do
interesting things that we don't know how to emulate in technology. It
is very likely that we will need a long hard look at how the brain
implements these functions, and this requires large-scale models of neural
activity. Today we have brain-sized simulations, but they are unwieldy, in
terms of the number of parameters that are required and the amount of data
they generate. A simulation method that reduces the complexity of these
simulations, but retains a close correspondence to the underlying spiking
neural dynamics is clearly desirable. Population density techniques show
great promise in this area. I will present a simulator that implements
algorithms based on computational geometry. We can visualize a neural
model and then turn it into a simulation of population dynamics. I will
show how the method works, invoking simple geometrical arguments and
present first simulation results of neural circuits.
