Neural activity during a four-choice motion-discrimination task at J_sim = 1.32 and J_opp = 1.01. A, B, Spatiotemporal firing patterns of pyramidal cells (A) and interneurons (B) in a sample trial with 6.4% motion coherence. The coherent motion direction is at 45°. Each neuron is labeled by its preferred direction. C, Temporal evolution of mean firing rates of neural pools separately located at 0° (solid), 90° (dashed), and 180° (dotted) relative to the coherent motion direction, averaged over 500 correct trials, for different coherence levels. A 0.45 s segment is expanded at the bottom.
