Abstract

Using optical coherence tomography angiography, we measured blood flow from the vessels in the lateral wall in the mouse cochlea directly through bone in mice with and without sympathetic neuronal function. We present in vivo imaging of blood flow and mechanical vibration in mice subjected to 30 min of loud sound. Loud sound caused blood flow reduction. In mice with superior cervical ganglion ablation, the loud sound-induced reduction in blood flow was partially ameliorated. These results demonstrate that sympathetic innervation likely plays a role in the pathological decrease in blood flow observed in the lateral wall vessels in response to loud sound.
