Before revision:  demonstrating event-based computation with short latencies. 4) The chaotic sub-manifold predicts a transient increase of variability after stimulus onset. Our results thus provide a hitherto unknown link between recurrent and chaotic dynamics of functional networks, neuronal variability, and dimensionality of neuronal responses .
After revision:  demonstrating event-based computation that may be exploited by biological neural systems, for which we propose testable predictions .
