TLDR
This finding revealed that patients failed to show an increase in coherence during talking, especially over the speech production and speech reception areas of the left hemisphere, and especially in patients prone to hallucinate.About:

Abnormal neural oscillations and synchrony in schizophrenia
TL;DR: Dysfunctional oscillations may arise owing to anomalies in the brain's rhythm-generating networks of GABA (γ-aminobutyric acid) interneurons and in cortico-cortical connections.

TL;DR: Among patients, the magnitude of MPFC task suppression negatively correlated with default connectivity, suggesting an association between the hyperactivation and hyperconnectivity in schizophrenia.

Perceiving is believing: a Bayesian approach to explaining the positive symptoms of schizophrenia
TL;DR: It is suggested that it is possible to understand the symptoms of mental illness in terms of a disturbed hierarchical Bayesian framework, without recourse to separate considerations of experience and belief.

Dysconnection in Schizophrenia: From Abnormal Synaptic Plasticity to Failures of Self-monitoring
TL;DR: It is argued that this neurobiological mechanism can explain failures of self-monitoring, leading to a mechanistic explanation for first-rank symptoms as pathognomonic features of schizophrenia, and may provide a basis for future diagnostic classifications with physiologically defined patient subgroups.

Fronto-parietal EEG coherence in theta and upper alpha reflect central executive functions of working memory.
TL;DR: The results indicate the involvement of prefrontal areas in executive functions reflected by a decrease of anterior upper alpha short-range connectivity and a parallel increase of fronto-parietal long-range coherence mirroring activation of a fronto -parietal network.

The Brief Psychiatric Rating Scale
John E. Overall,Donald R. Gorham +1 more
TL;DR: The Brief Psychiatric Rating Scale (BRS) as mentioned in this paper was developed to provide a rapid assessment technique particularly suited to the evaluation of patient change, and it is recommended for use where efficiency, speed, and economy are important considerations.

Structured clinical interview for DSM-IV axis I disorders : SCID-I : clinical version : scoresheet
TL;DR: The SCID-I is an efficient, user-friendly instrument that covers those DSM-IV diagnoses most commonly seen by clinicians and includes the diagnostic criteria for these disorders with corresponding interview questions and provides extensive documentation of the diagnostic process.

A new method for off-line removal of ocular artifact.
TL;DR: EMCP permits retention of all trials in an ERP experiment, irrespective of ocular artifact, and has the advantage that separate correction factors are computed for blinks and movements and that these factors are based on data from the experimental session itself rather than from a separate calibration session.

Oscillatory responses in cat visual cortex exhibit inter-columnar synchronization which reflects global stimulus properties.
TL;DR: It is demonstrated here that neurons in spatially separate columns can synchronize their oscillatory responses, which has, on average, no phase difference, depends on the spatial separation and the orientation preference of the cells and is influenced by global stimulus properties.
