Sensory cells and neurons in the ear communicate by secreting neurotransmitter in response to sound stimuli. Scientists of the University Medical Center Göttingen, the Cluster of Excellence Multiscale Bioimaging, and the Max Planck Institute for Multidisciplinary Sciences describe new details of this process that regulates the release of neurotransmitters and thus control the transmission of sound stimuli. The results of this work were published in the renowned journal Proceedings of the National Academy of Sciences (PNAS).
