Background: Schizophrenia is associated with changes in inhibitory and facilitatory brain networks which can be assessed by motor cortex excitability. Objective: Here, we investigate differences between large cross-sectional samples of un-medicated and medicated patients with schizophrenia and healthy controls in single- and double-pulse transcranial magnetic stimulation parameters. Methods: We measured right abductor digiti minimi muscle activity in 71 un-medicated, 43 medicated patients and 131 healthy controls. To exclude sample bias analyses were repeated with groups comparable for age and gender (un-medicated: n = 43; medicated: n = 38; controls: n = 49). Results: Un-medicated patients showed increased short-interval intracortical inhibition (SICI) in contrast to medicated patients and healthy controls. No group differences were found for resting and active motor threshold, cortical silent period and intracortical facilitation. Conclusion: Increases in SICI are in contrast to literature and highlight the necessity for large-scaled multi-centric studies with high methodological standards. (C) 2018 Elsevier Inc.
