In this study, we applied the technique for simultaneous
fMRI and skin conductance recordings in a comparison of
schizophrenia patients and a larger group of healthy comparison
subjects. Schizophrenia was considered in terms
of paranoid and nonparanoid subgroups, given our previous
observation that neural responses to fear differ across
these subtypes (21). Our predictions drew on neurophysiological
evidence for a disjunction in autonomic and central
responses to emotion in schizophrenia (7). We hypothesized
that schizophrenia patients would show dysregulation
most apparent in the visceral system: abnormally
