FIGURE 4. Scatter plots show the most significant EC correlations in NC and AD patients. (A) Correlations between percentage nrCMRgl values extracted from the left and right EC and the left and right inferior parietal lobule (IPL) in NC (diamonds). Note that the left and right EC both show bilateral significant correlations with the IPL. (B) Correlations between percentage nrCMRgl values extracted from the left and right EC and the left and right inferior temporal cortex (ITC) in AD patients (triangles). Note that in AD patients the left EC is related to the left ITC (R = 0.35) but not to the right ITC (R = 0.002; not significant) and vice versa, with the right EC correlated with the right ITC (R = 0.41) but not with the left ITC (R = 0.06; not significant), despite being, on the whole, the most related areas in AD. Regression models and correlation coefficients (R) are reported at the top of each graph.
