Stimulus discrimination task and behavioral performance. a A schematic of the behavioral paradigm used. An individual trial started when trained rats placed their nose in the central port. Next, a lone auditory stimulus or a combined auditory and visual stimulus was presented via a centrally positioned light emitting diode (LED) and speaker to cue the location for a water reward. When the stimulus was either a 10 kHz pure tone (A10k) or a combination of a 10 kHz pure tone and a flash of light (VA10k), the animal would be rewarded at the left port. If the stimulus given was a 3 kHz pure tone alone (A3k) or the same tone paired with a flash of light (VA3k), the animal would receive the reward in the right port. Trials of different stimuli combinations (A3k, A10k, VA3k, VA10k) were presented in a randomized order. b The correct response rate (the number of correct trials divided by the total number of trials, overall mean, black line) are shown for 7 complete testing sessions using 9 well-trained animals (Error bar, SEM). c The mean correct rate across all animals for each stimulus condition (Error bar, SEM). d The distribution of reaction times for both auditory (gray) and multisensory (black) trials performed by a well-trained animal. e A comparison of mean reaction times between auditory and multisensory trials across all animals. **, p < 0.001
