Relating Neuronal Firing Patterns to Functional Differentiation of Cerebral Cortex

Figure 4

A MDS map of cortical neuronal firing based on LvR.

The map plots the first and second components of Kruskal's nonmetric multidimensional scaling (MDS) analysis for the Hellinger distances of the metric distributions for all combinations of 19 neuronal data sets. The primary motor, higher-order motor, visual, and prefrontal areas are indicated by black hexagons, blue pentagons, red triangles, and green squares, respectively. The number in brackets next to the notation for each cortical area indicates data sets 1–19 shown in Figure 3C and Table 1.
