TL;DR: It is concluded that correlated, low-frequency oscillations in human fMRI data have a small-world architecture that probably reflects underlying anatomical connectivity of the cortex, and could provide a physiological substrate for segregated and distributed information processing.

TL;DR: Functional MRI demonstrates a neurophysiological architecture of the normal human brain that is anatomically sensible, strongly symmetrical, disrupted by acute brain injury, subtended predominantly by low frequencies and consistent with a small world network topology.

TL;DR: The partial coherency spectrum between a pair of human brain regional fMRI time-series depends on the anatomical distance between regions: long-distance edges represent conditional dependence between bilaterally symmetric neocortical regions and between regions of prefrontal and parietal association cortex in the same hemisphere, are predominantly subtended by low-frequency components.

TL;DR: Cognitive-behavioural therapy has a therapeutic effect on schizophrenic symptoms in the 'small' range, which reduces further when sources of bias, particularly masking, are controlled for.

TL;DR: Patients with schizophrenia show both failure to activate and failure to deactivate during performance of a working memory task, including an area in the anterior prefrontal/anterior cingulate cortex that corresponds to one of the two midline components of the ‘default mode network’ implicated in functions related to maintaining one's sense of self.
