Architectures for both models simulated in this article. Diamonds represent Izhikevich medium spiny neuron units, circles represent quadratic integrate-and-fire units, squares represent Izhikevich regular spiking neuron units. (SMA = supplementary motor area, GPi = internal segment of the globus pallidus, VL = ventral-lateral nucleus of the thalamus, VA = ventral-anterior nucleus of the thalamus)
