Full-scale network stimulation. Snapshots from a movie (suppl. Movie 2) illustrating a simulation in which the activity was evoked by a single pulse stimulation delivered to about 200 pyramidal cells in a 100 µm diameter sphere near the CA3 side. As in the case of Fig. 8, the activity propagates in the Antero-posterior direction from CA3 to subiculum to subsequently spread longitudinally while remaining confined to the subiculum side. Scale bar 1 mm. As in the case of Fig. 8, a neuron’s activity is color coded from blue (rest) to white (spike), to visualize action potentials, with a fixed 2 ms transition time.
