Sensory hyperacuity in the jamming avoidance response of weakly electric fish.
Sensory systems often show remarkable sensitivities to small stimulus parameters. Weakly electric fish are able to resolve intensity differences of the order of 0.1% and timing differences of the order of nanoseconds during an electrical behavior, the jamming avoidance response. The neuronal origin of this extraordinary sensitivity is being studied within the exceptionally well understood central mechanisms of this behavior.
