Fig. 1: Delta/alpha frequency activity during three testing conditions: resting eyes closed (REC), resting eyes open (REO) and continuous performance task (CPT) in four groups: control (CON, n = 29), schizophrenia (SCZ, n = 28), bipolar I disorder with history of psychosis (BPD, n = 28) and methamphetamine-induced psychotic disorder (MPD, n = 24). | Translational Psychiatry

Fig. 1

a Delta/alpha frequency activity during REC was lower for CON than SCZ and MPD globally, and lower for BPD than MPD for right hemisphere electrodes (F4, C4, P4). b Delta/alpha frequency activity during REO was lower in CON than SCZ, BPD and MPD for all electrodes except left frontal (F3). c Delta/alpha frequency activity during the CPT was lower in CON than BPD and MPD for all electrodes except left frontal (F3). Median, interquartile and range are reported; p < 0.05
