From: EEG/ERP evidence of possible hyperexcitability in older adults with elevated beta-amyloid
Pearson r correlations between beta-amyloid (Aβ) standard uptake value ratio and P3 event-related potential latency and amplitude for each n-back test at channel Fz, Cz, and Pz. The color heat map shows the magnitude of the correlations in the positive (green) and negative (red) direction. Bolded values are significant (P < 0.05). Top panel a shows correlations for the cognitively normal, elevated (CNAβ+) group; bottom panel b shows the correlations for the cognitively normal, non-elevated (CNAβ−) group
