A pattern with two versions of a “slow down” signal was replicated throughout the study, with one long, continuous note used to slow or soothe an animal and one sharp note to immediately stop a fast-moving one. If you think about it, it makes sense that “inhibiting” signals would fall into two different categories, since slowing or calming down is a distinctly different response than gathering up the energy to put on the brakes if you’re in a dead run.
