Fig. 2: Timing of neural activation in active compared to passive condition.

a Earlier activation in healthy control (HC) shown at Z = 0, Y = 0, X = 14; (b) earlier activation in schizophrenia spectrum disorder (SSD) shown at Z = 0, Y = 0, X = 14; (c). common earlier activated brain areas between HC and SSD at Z = 60, Y = 0, X = 26, (d) earlier activation specific to HC compared to SSD shown at Z = 8, X = 10; (e) interaction related earlier activation in HC compared SSD patients shown at Z = 14, Y = −18, X = −28; f active with own hand feedback specific earlier activated brain area in HC compared to SSD patients shown at Z = 10, X = −36. Positive eigenvariates reflect earlier activation while negative reflects later activation timing in the bar graph. HC healthy control, (n = 20); SSD schizophrenia spectrum disorder, (n = 20).
