Adapting to delayed sensory feedback following an action produces a subjective time compression between the action and the feedback (this is known as the temporal recalibration effect, TRE). TRE is important for sensory delay compensation to maintain a relationship between causally related events; however, it was unclear whether TRE was a sensory modality-specific phenomenon. In 3 experiments using a sensorimotor synchronization tasks, lab member Ali Aytemur and colleagues investigated this question using cathodal transcranial direct-current stimulation (tDCS). Through these experiments, they found that stimulation of the visual and auditory cortex decreased visual temporal recalibration; however, auditory temporal recalibration was robust against stimulation. These studies reveal that visual temporal recalibration is sensory specific and modulated by the auditory system, and that visual timing information might be transformed into auditory representation.
