Functional neuroimaging studies to date have shown prefrontal dysfunction during executive
tasks in schizophrenia. However, relationships between hemodynamic response in …

BACKGROUND: Previous studies have shown that near-infrared spectroscopy (NIRS) has
high temporal resolution, requires little restraint, and is suitable for examining the effect of …

In schizophrenia, dysfunction of the prefrontal cortex (PFC), regarded as a core feature of the
disease, has been investigated by different neuroimaging methods. Near infrared …

Recent neuroimaging studies have shown similarities and differences in prefrontal
abnormalities between patients with schizophrenia (SZ) and major depressive disorder …

Near-infrared spectroscopy (NIRS) allows noninvasive, in vivo measurement of changes in
the concentrations of oxygenated hemoglobin (O2Hb) and deoxygenated hemoglobin (HHb) …

Near-infrared spectroscopy (NIRS) is an optical imaging method that allows non-invasive in-
vivo measurements of changes in the concentration of oxygenated (O2Hb) and …

BACKGROUND: Symptomatic and functional outcomes in schizophrenia are associated with
the duration of untreated psychosis. However, no candidate biomarkers have been adopted …

We assessed the cerebral hemoglobin oxygenation response in the left frontal area in 62
schizophrenia patients and 31 healthy subjects during a verbal fluency test (VF) and letter …

Letter-or semantically-cued verbal fluency tests (VFT) induce different, but overlapping
activities in the prefrontal cortex (PFC) in healthy subjects. Functional differences between …

Regional cerebral blood flow (rCBF) was measured with single photon emission computed
tomography (SPECT) in six neuroleptic-naive, young, acute schizophrenic patients and six …
