Trans-tympanic Infrared Laser Stimulation Evokes Auditory-Like Perception in Mongolian Gerbils

Caption

Top: Gerbils learned that both sound (blue) and laser stimulation (red) predicted a water reward, with similar learning curves. Middle: Loud background noise weakened responses driven by both sound (blue) and laser stimulation (red), suggesting that the laser signal was linked to hearing. Bottom: Gerbils trained with sound also responded to laser stimulation, suggesting that laser stimulation created a sound-like sensation.
