Response Monitoring Theta-Band Activities Across Emotional Contexts in Schizophrenia and Bipolar Spectrum Disorders.

ABSTRACT:

Background

Schizophrenia spectrum disorder (SZ) and bipolar spectrum disorder (BD) have traditionally been treated as different conditions but share many characteristics, including cognitive control deficits. Electroencephalogram (EEG) indicators of response monitoring, including error-related negativity (ERN) and theta-band activities (4-8 Hz), have been proposed as transdiagnostic indicators of cognitive control. Research has found that the ERN and theta power are blunted in SZ, but findings have been less consistent in BD. Individuals with SZ and BD also show difficulty in emotional contexts. However, no research has investigated response-monitoring theta activities in SZ and BD concurrently or in emotional contexts.

Methods

Data were collected from 32 participants with S
