Different trajectories can drive multiple spatiotemporal patterns in output neurons. A, Trajectory A drives output neurons to generate output pattern A'. Raster plots of two trajectories (cyan: input A; yellow: input B) sorted by the trajectory A (left); output pattern A in which five output neurons fire at different times (middle); voltage traces of the output neurons show that they fire at their target time during the test trials (right). B, Similar to A, trajectory B drives the same five output neurons to generate a different spatiotemporal output pattern B'. Raster plots of same two trajectories sorted by trajectory B (left); the reversed temporal patterns from that in A was used as the target (middle and right).
