Abstract Thought disorder is one of the primary symptoms in schizophrenia, yet the neural
correlates and related semantic processing abnormalities remain unclear. We aimed to …

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

Background: Functional near-infrared spectroscopy (fNIRS) has many advantages over
other neuroimaging modalities for routine measurement of task-dependent cortical …

Relationships between deficits in verbal fluency and poor social functioning have been
revealed in patients with schizophrenia. In previous studies, we demonstrated that deficits in …

Cognitive impairment and associated frontal lobe dysfunction characterize schizophrenia.
The letter fluency test (LFT) has been used as one of the most sensitive measures of the …

As a means toward understanding the neural bases of schizophrenic thought disturbance,
we examined brain activation patterns in response to semantically and superficially encoded …

Formal thought disorder (FTD) is a core feature of schizophrenia, a marker of illness severity
and a predictor of outcome. The underlying neural mechanisms are still a matter of debate …

Abstract Thought disorder is a core symptom of schizophrenia. However, the underlying
mechanism is not well understood. Functional MRI (fMRI) was used to examine the neural …

We investigated whether the retrosplenial and the posterior cingulate cortex (RS-PCC) is
functionally impaired in schizophrenia patients. Therefore, we measured functional magnetic …

This study examined the hypothesis that a fronto-temporal disconnection in the language
network underpins formal thought disorder (FTD) in schizophrenia. Forty-nine patients with a …
