Fig. 3.
An example of cross sectional image for the primary visual cortex (a) and the curve fitting for the depth profiles (b). Scale bar: horizontal, 300 μm; vertical, 100 μm. The arrows in (a) indicate the position of the depth profiles (red) and fitting (black) shown in (b). L2/3: layer 2/3; WM: white matter. The zero depth in (b) indicates the location of the tissue surface.
