The cholinergic contribution to the resting state functional network in non demented Parkinson’s disease

2018
Sci Rep
PMCID: 5955917
PMID: 29769626
DOI: 10.1038/s41598-018-26075-3

[…] Functional brain MRI analyses were performed following a previously described method. Preprocessing of resting-state fMRI data was conducted using the Analysis of Functional NeuroImages, (http://afni.nimh.nih.gov/afni) software. For stabilization of the magnetic field, the initial five volumes from each functional image were eliminated. The eliminat […]

Prefrontoparietal dysfunction during emotion regulation in anxiety disorder: a meta analysis of functional magnetic resonance imaging studies

2018
PMCID: 5953307
PMID: 29785110
DOI: 10.2147/NDT.S165677

[…] methodological differences between studies, we then performed several subgroup meta-analyses including medicine-naive patients, patients with SAD, patients with GAD and SAD, data processing software (AFNI), and MRI field strengths (3.0 T). Given the variability that exists in treatment status, we defined the sample of medicine-naive patients as participants who had been free of psychotropic medica […]

Altered Amygdala Resting State Functional Connectivity and Hemispheric Asymmetry in Patients With Social Anxiety Disorder

2018
PMCID: 5932339
PMID: 29755374
DOI: 10.3389/fpsyt.2018.00164

[…] Anatomical T1 images were coregistered to the first functional image using a local Pearson correlation cost function (). Preprocessing of imaging data was performed using Analysis of Functional NeuroImages (AFNI; http://afni.nimh.nih.gov/afni) software (). The first three volumes from each functional image were removed. We used Physiologic EStimation by Temporal ICA (P […]

Brief exposure to obesogenic diet disrupts brain dopamine networks

2018
PLoS One
PMCID: 5919534
PMID: 29698491
DOI: 10.1371/journal.pone.0191299

[…] d using a one-way ANOVA followed by a Newman-Keuls post-hoc test. Group mean %ΔCBV maps were generated after affine warping (3dWarpDrive) of functional maps to a common anatomic reference image using AFNI (http://afni.nimh.nih.gov/afni) []. The %∆CBV response slopes (m) between time points 21 and 40 min were calculated for dorsal and ventral striatum, and the slope values for LF versus HF groups w […]

Converging Evidence From Electrocorticography and BOLD fMRI for a Sharp Functional Boundary in Superior Temporal Gyrus Related to Multisensory Speech Processing

2018
Front Hum Neurosci
PMCID: 5928751
PMID: 29740294
DOI: 10.3389/fnhum.2018.00141

[…] ce (Setsompop et al., ) with TR = 1500 ms, TE = 30 ms, flip angle = 72°, in-plane resolution of 2 × 2 mm, 69 2-mm axial slices, multiband factor: 3, GRAPPA factor: 2. fMRI data was analyzed using the afni_proc.py pipeline (Cox, ). Data was time shifted to account for different acquisition times for different slices; aligned to the first functional volume which was in turn aligned with the high-res […]
