Rats Use X-ray Vision-Like Sixth Sense

Introduction to the structure of the task. Two views of a rat performing a single trial of the IR-discrimination task. The IR light comes on, and when the rat orients toward the stimulus, an IR-signal is registered by an IR-detector on the rat’s head, and S1 is stimulated with a frequency that depends on detector’s output (Figure 1e). Guided by microstimulation, the rat approaches the reward port to receive water. In the floor-level view, you can see the infrared detector attached to the rat’s head. The audio track is the output of the microstimulator, which is not available to the rat.
