Same circuit as in Figure 6, except that excitatory threshold-to-accumulator feedback is included. The green trace now has a late ballistic component, reflecting the ballistic activation of the threshold latch. Positive feedback also shortens the decision time considerably relative to the same model without threshold-to-accumulator feedback.
