Comparison of physiological noise at 1.5 T, 3 T and 7 T and optimization of fMRI acquisition parameters
We investigate the amplitude of image intensity fluctuations in the fMRI time-course at magnetic field strengths of 1.5 T, 3 T, and 7 T as a function of image resolution, flip angle and TE. Expand

Differential selectivity for dynamic versus static information in face-selective cortical regions
Neuroimaging studies have identified multiple face-selective regions in human cortex but the functional division of labor between these regions is not yet clear. Expand

Distinct Regions of Right Temporo-Parietal Junction Are Selective for Theory of Mind and Exogenous Attention
In functional magnetic resonance imaging (fMRI) studies, a cortical region in the right temporo-parietal junction (RTPJ) is recruited when participants read stories about people's thoughts (‘TheoryExpand

Feedback of pVisual Object Information to Foveal Retinotopic Cortex
The mammalian visual system contains an extensive web of feedback connections projecting from higher cortical areas to lower areas, including primary visual cortex. Although multiple theories haveExpand

Similar Brain Activation during False Belief Tasks in a Large Sample of Adults with and without Autism
Reading about another person’s beliefs engages ‘Theory of Mind’ processes and elicits highly reliable brain activation across individuals and experimental paradigms. Using functional magneticExpand

Predicting treatment response in social anxiety disorder from functional magnetic resonance imaging.
CONTEXT Current behavioral measures poorly predict treatment outcome in social anxiety disorder (SAD). To our knowledge, this is the first study to examine neuroimaging-based treatment prediction inExpand

Effect of spatial smoothing on physiological noise in high-resolution fMRI
Physiological noise dominates the SNR of the fMRI time-course at commonly used spatial resolutions at field strengths of 3 T and above. Expand

3T phased array MRI improves the presurgical evaluation in focal epilepsies
Background: Although detection of concordant lesions on MRI significantly improves postsurgical outcomes in focal epilepsy (FE), many conventional MR studies remain negative. The authors evaluatedExpand

Atypical brain activation patterns during a face‐to‐face joint attention game in adults with autism spectrum disorder
Joint attention behaviors include initiating one's own and responding to another's bid for joint attention to an object, person, or topic. Joint attention abilities in autism are pervasivelyExpand

Physiological noise and signal-to-noise ratio in fMRI with multi-channel array coils
Sensitivity in BOLD fMRI is characterized by the signal to noise ratio (SNR) of the time-series (tSNR), which contains fluctuations from thermal and physiological noise sources. Expand
