Fig. 2.

Matrix heat plot with hierarchical cluster dendrogram (left margin). The degree of brain damage is given as a number in each cell and as he cells' color code (from light yellow to (dark) red). The plot provides an overview of the brain lesion pattern of the present patients (rows, n = 127, patients ID codes shown at the right). The brain regions that had provided sufficient information to pass the ABC analysis of the Shannon information are shown at the abscissa (columns, n = 27). The dendrogram at the left shows the result of Ward hierarchical cluster analysis group the patients for brain lesion pattern. Three clusters emerged (color bar next right of this dendrogram; cluster numbers indicated). In addition, observations of olfactory dysfunction are shown as colored lines at the succeeding bars. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
