Lauren Probe Schematic.PNG Probe schematic: A fiber optic optical coherence tomography (OCT) probe, designed by Nathan Lin (Lin et al., 2019), has been used to image and measure vibrations of the organ of Corti complex (OCC) (left). The OCT probe is currently being adapted to include a voltage-sensing electrode to simultaneously measure vibrations and the local cochlear microphonic (LCM) voltage (right).

Lauren Probe Image.jpg Probe image: The fiber optic OCT probe utilizes a GRIN lens with a focal length of approximately 350um in water. The fiber is designed to be offset from the end of the electrode by this amount so that voltage recordings will be taken where the imaging and motion measurements for OCT are at the optimal focal length.
