Towards Real-Time, Mouse-Scale Cortical Simulations

We have designed and implemented a massively parallel cortical simulator. The simulator is designed for low to moderate complexity spiking neurons, for example, [2]. The state of each neuron is updated synchronously at a user-specified resolution, say, 1ms. Each neuron can be presynaptic to a realistic number of target neurons. Each synapse can implement STDP [3]. The simulator also incorporates axonal conductance delays ranging from a low of one time step to a model-defined maximum.
