Figure 8.

Brain region-specific exploration of the data using linked plots painted by user-defined group. Corresponding to the data represented in Figure 7, but focusing only on the superior frontal gyrus sub-volumes, histograms for the group consisting of mostly healthy subjects is given (left), while a red group is largely comprised of patients with Alzheimer’s Disease. Thus, from the examination of how brain morphometry clusters in a derived feature space explored using INVIZIAN, a user can quickly and interactively discover that normal subjects exhibits a larger mean thickness in frontal cortices than do patients. Such a hypothesis can be examined more closely by downloading the original data from the database or tested more precisely through the collection of new empirical brain imaging data.
