Mitochondria Volumes and Abundance at the Calyx of Held

Caption

This image shows two volumetric electron microscopy reconstruction models of mitochondria within the calyx of Held and its axon from 7 (red) and 21 (blue) day old mice. Mitochondria volumes and abundance at the calyx of Held, a large glutamatergic presynaptic terminal in the auditory brainstem, increase after the onset of hearing to support the energetic demands of high-fidelity action potential firing required in the initial stages of auditory processing. As seen on the Journal of Neuroscience cover of the 9 Oct. 2019 Volume 39, issue 41.
