Sensorimotor integration on a rapid time scale
Abstract
Humans and other animals continuously monitor sensory information to inform the selection of motor commands for adaptive behaviors. Acoustic communication, for example, utilizes auditory feedback to fine-tune vocal production parameters. Because most animal species produce vocalizations that last several hundred milliseconds, it is difficult to dissect the temporal dynamics of audio-vocal feedback control. Here we took advantage of the brief echolocation signals of bats and mapped out the time course of vocal adjustments to background noise on a millisecond time scale. The high temporal resolution data provided the foundation for the model of audio-vocal volume control. We discovered that temporal summation, a shared auditory process across the animal kingdom, lies at the core of adaptive vocal volume control.
