Figure 1: Scheme for constructing the standard brain. (a) Brain LSM image data consisting of multi-page image stacks. (b) Averaged brain image data (section 90 of the set of 154 optical sections of 2 μm thick optical sections is shown). (c) Average shape of the silkmoth brain obtained by binarization and surface modeling. (d) High-resolution brain image was registered by fitting to the standard brain shape using a nonrigid transform. (e) Segmented regions and neurons were registered in the standard brain by a nonrigid transform with defined landmarks.
