TLDR
In this article, the anatomical location, spatial extent, and magnitude of signal loss artifacts were quantitated for a common whole-brain fMRI technique, and the signal loss was primarily localized to inferior frontal regions and to inferior lateral temporal lobe (including part of fusiform gyrus) bilaterally.About:

The human brain is intrinsically organized into dynamic, anticorrelated functional networks
Michael D. Fox,Abraham Z. Snyder,Justin L. Vincent,Maurizio Corbetta,David C. Van Essen,Marcus E. Raichle +5 more
TL;DR: It is suggested that both task-driven neuronal responses and behavior are reflections of this dynamic, ongoing, functional organization of the brain, featuring the presence of anticorrelated networks in the absence of overt task performance.

Spurious but systematic correlations in functional connectivity MRI networks arise from subject motion
Jonathan D. Power,Kelly Anne Barnes,Abraham Z. Snyder,Bradley L. Schlaggar,Steven E. Petersen +4 more
TL;DR: The results suggest the need for greater care in dealing with subject motion, and the need to critically revisit previous rs-fcMRI work that may not have adequately controlled for effects of transient subject movements.

TL;DR: In this paper, the organization of networks in the human cerebrum was explored using resting-state functional connectivity MRI data from 1,000 subjects and a clustering approach was employed to identify and replicate networks of functionally coupled regions across the cerebral cortex.

Resting-State Functional Connectivity in Major Depression: Abnormally Increased Contributions from Subgenual Cingulate Cortex and Thalamus
Michael D. Greicius,Benjamin H. Flores,Vinod Menon,Gary H. Glover,Hugh B. Solvason,Heather A. Kenna,Allan L. Reiss,Alan F. Schatzberg +7 more
TL;DR: The findings provide cross-modality confirmation of PET studies demonstrating increased thalamic and subgenual cingulate activity in major depression and suggest that a quantitative, resting-state fMRI measure could be used to guide therapy in individual subjects.

The Fusiform Face Area: A Module in Human Extrastriate Cortex Specialized for Face Perception
TL;DR: The data allow us to reject alternative accounts of the function of the fusiform face area (area “FF”) that appeal to visual attention, subordinate-level classification, or general processing of any animate or human forms, demonstrating that this region is selectively involved in the perception of faces.

TL;DR: In this paper, a series of images were acquired continuously with the same imaging pulse sequence (either gradient echo or spin-echo inversion recovery) during task activation, and a significant increase in signal intensity (paired t test; P less than 0.001) of 1.8% +/- 0.9% was observed in the primary visual cortex (V1) of seven normal volunteers.

Oxygenation-sensitive contrast in magnetic resonance image of rodent brain at high magnetic fields.
TL;DR: At high magnetic fields (7 and 8.4 T), water proton magnetic resonance images of brains of live mice and rats under pentobarbital anesthetization have been measured by a gradient echo pulse sequence with a spatial resolution of 65 × 65‐ μm pixel size and 700‐μm slice thickness.
