Table 3 Correlations among the anhedonia symptoms as quantified by the Snaith-Hamilton Pleasure Scale (SHAPS) before and after treatment and the change in those scores (SHAPS_Post minus SHAPS_Pre) and the indices of Frontal Alpha asymmetry (FAA) and Posterior Alpha Asymmetry (PAA). Note: Significant p-values are in bold.
From: Effect of DLPFC rTMS on anhedonia and alpha asymmetry in depressed patients
