Bat cries as viewed through moth ears Moths are tethered. Faint ultrasound just loud enough for moth s ear to detect it. Results in two action potentials fm. Stronger ultrasound representing bat as closer to moth. Still gives two action potentials fm.
Latency is unaltered.
But pulse interval is decreased. A1 cell travelling together. Also latency to first spike has been reduced. And a further decrease in spike interval. Bat is now very close Latency to first spike is further decreased.
