Testing the neurovisceral integration model in schizophrenia and obsessive compulsive disorder: the effect of autonomic nervous system on eye-movements

Abstract

Neurovisceral Integration Model (NIM) proposes the existence of a brain-heart link with a network connecting prefrontal cortical areas to various subcortical regions from basal ganglia and thalamus to vagus nerve and the heart. This study examined the connection between two prominent deficits in schizophrenia: the deficit in parasympathetic regulation and the deficit in cognitive inhibitory control, within the framework of NIM. Then the relationship of these functions was also examined in obsessive-compulsive disorder (OCD) where findings as to whether a deficit occurs in patients are contradicting.Thirty healthy controls, 30 patients with schizophrenia and 28 patients with OCD performed the internationally standardized antisaccade protocol while their electrocardiographic data were recorded. The interaction between group, cognitive inhibitory control, measured by error rate (ER) in the antisaccade task, and parasympathetic activity, measured by high frequency component of Heart Rate V ...
