Dual-task paradigm is a behavioral procedure in which subjects are required to perform two independent tasks in parallel, each of which involves a distinct stimulus-response association that leads to a unique goal. Although dual tasks are widely used in human studies, they are seldom used in animals. One such rare case was a rat simultaneous temporal processing (STP) task, in which rats were asked to time two different intervals simultaneously(1). However, there are a few limitations in this paradigm, such that, for example, each of the two component tasks was not clearly associated with a unique stimulus-response association. In this report, in order to better characterize temporal dual-task performance in rats, we developed a modified version of the STP task that was comprised of two clearly-divided component tasks, and equipped our experimental system with a novel video-based motion tracking system. We show that even under this more rigidly controlled dual-task setting, rats are able to time two different intervals virtually without interference, and that our tracking system can simultaneously detect head-direction and body-location of a rat with high accuracy. These results suggest that the present experimental paradigm should be useful for investigating cognitive processes that underlie dual-task performance at both the behavioral and neuronal levels.
