Intersensory attention deficits in schizophrenia relate to ongoing sensorimotor beta oscillations.

ABSTRACT: This study tested whether intersensory attention deficits in people with schizophrenia (SZ) relate to aberrant ongoing oscillations in sensory cortices. Electroencephalography (EEG) was recorded while individuals with schizophrenia (N = 27) and healthy controls (HC; N = 27) performed a visual-tactile target detection task. Ongoing alpha (8-12 Hz) and lower beta (13-20 Hz) band oscillations in visual and sensorimotor cortices were examined. Behavioral data suggested an intersensory attention deficit in patients. EEG data revealed stronger alpha-band oscillations for tactile vs. visual attention conditions in the visual cortex of both study groups. In the sensorimotor cortex contralateral to the tactile stimulation site, patients showed an additional intersensory attention effect in ongoing
