Crows' Minds Move Faster
A study by the University of Tübingen found that two ravens made visual decisions twice as fast as humans and monkeys. They identified the direction in which dots were moving in an average of 235 milliseconds, and their accuracy reached nearly 100% when the signals were clear. The researchers tested the birds using a touchscreen and recorded neurons beginning to distinguish the direction of movement after 70 milliseconds. They noted that ravens use neural mechanisms similar to those of humans and other primates, despite differences in brain structure.
