Optical Coherence Tomography: Basic Concepts and Applications in Neuroscience Research

Figure 5

Details of the response in an unstained squid nerve. (a) Action potential recording; (b) image at ∼10.5 ms and (c) traces of selected pixels from an unstained nerve with an averaging of 90 trials. Arrow in (b) indicates the turning point of the galvanometer mirror; scale bars: horizontal, 10 μm; vertical, 100 μm. Pixel coordinates in (c) are in the form of (lateral index, depth index), and the locations are marked by blue circles in (b). The blue trace is the action potential recording for the registering time (reprinted with permission from [62]).
