left temporoparietal junction and the bilateral anterior cingulate as well as the bilateral amygdala was associated with worse auditory hallucinations (Vercammen et al., 2010a). With regards to the underlying cerebral pathology, the most consistent abnormalities have been noted in the posterior superior temporal cortex of the dominant left hemisphere. However, structural/functional abnormalities have also been noted in a distributed network of brain regions, including Broca’s area and the amygdala-hippocampal network (Allen et al., 2008). fcEEG analysis has suggested that in schizophrenic patients, brain networks resemble random graphs, with relatively small ratios of clustering-coefficients (local efficiency) to path-length values, compared to the larger ratios characteristic of the small-world networks which are seen in healthy controls (Micheloyannis et al., 2006a; Rubinov et al., 2009), suggesting a relative breakdown of local processing efficiency.
