ABSTRACT
Objective To investigate auditory sensory gating potential in the siblings of schizophrenic, to discover the neuroimaging features of sensory gating associated with schizophrenia as intermediate phenotypes. Methods Twelve siblings of schizophrenia patients in the first episodic, and 12 healthy controls matched in gender, age, education under?went MRI scan when performing a auditory sensory gating fMRI task (repeated clicks and single click auditory stimuli). The measure of sensory gating was the contrast of repeated clicks minus single click. The analysis of result was imple?mented in SPM2. Results Compared with healthy controls, schizophrenia patients showed significant overactivation in the right inter cingulate gyrus (x=4,y=8,z=32) and left anterior cingulate gyrus (x=-8,y=4,z=28) during the fMRI senso?ry gating task. Conclusion Sensory gating is overactivated in the cingulate gyrus in siblings of schizophrenic. This pat?tern may be a potential endophenotype of schizophrenia.
