摘要
The ability to perceive motion is a fundamental property of the visual system,and one of its most basic aspects is the ability to discriminate moving objects from motionless ones,for example,motion detection.Velocity thresholds represent the minimum rate of displacement over time unit that an animal is able to perceive as movement,any slower motion being not discriminable from a still object.Although such topic has grabbed the attention of scientists already at the beginning of the 20th century,the interest has waned in time,and velocity thresholds have thus far been assessed in only a handful of species.
