Figure 4.

(A) Example of an anatomical query, finding ions specific to the caudoputamen. The anatomical structure image of the caudoputamen is given as an input and the correlation table returns the spatial correlation to this structure for each ion image. Two examples of ion images that positively correlate with the target anatomical structure are displayed. (B) Example of an ion query, finding anatomical regions in which m/z 7841 is highly expressed. The ion image of m/z 7841 is given as an input, and the correlation table returns the spatial correlation to this ion image for all the anatomical regions. Two examples of anatomical structure images that positively correlate with the target ion image are displayed.
