Participants were scanned using a 4.0 Tesla Varian Unity INOVA Whole Body MRI/MRS system (Varian Inc., Palo Alto, CA, USA) at the Center for Imaging Research at the University of Cincinnati College of Medicine. To provide anatomical localization for activation maps, a high-resolution T1-weighted anatomical image was acquired using modified driven equilibrium Fourier transform, MDEFT (TMD = 1.1 s, TR = 13 ms, TE = 6 ms, FOV = 256 mm × 192 mm × 192 mm, matrix 256 × 192 × 96 mm, voxel resolution 1 mm × 1 mm × 2 mm, flip angle = 20°), zero-filled to 1 mm × 1 mm × 1 mm during reconstruction. For fMRI measurements, we acquired T2*-weighted gradient-echoplanar images (EPI) (TR/TE = 3,000/29 ms, FOV = 208 mm × 208 mm, matrix 64 × 64, slice-thickness 5 mm, flip angle = 75°, resolution 3.25 mm × 3.25 mm × 5 mm) during presentation of faces.

Imaging was conducted at the University of Cincinnati's Center for Imaging Research, using a 4.0 T Varian, Unity INOVA Whole Body MRI/MRS System (Varian, Inc., Palo Alto, CA). To provide an anatomical reference for the fMRI data, a T1-weighted, 3-D anatomical brain scan was first obtained using a modified driven equilibrium Fourier transform sequence (TMD = 1.1 s, TR = 13 ms, TE = 6 ms, FOV = 25.6 × 19.2 × 19.2 cm, matrix 256 × 192 x 96 pixels, flip angle = 20°, 15″). fMRI scans were acquired using an RF-spoiled FAST 3-D acquisition technique. Functional images were collected while performing the stress task using a T2*-weighted gradient-echo echoplanar imaging (EPI) pulse sequence (TR/TE = 2000/30 ms, FOV = 25.6 × 25.6 cm, matrix 64 × 64 pixels, slice-thickness = 4 mm, flip angle = 75°, 35 slices in coronal orientation). Sixteen minutes of the hour-long scan were dedicated to the control (5 min) and stress tasks (11 min), respectively (see fMRI Stress Task below). A neuroradiologist assessed each scan for brain abnormalities and found none.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
