Multimodal Neuroimaging of Healthy Participants

Check if the same lab product or an alternative is used in the 5 most similar protocols

Twenty-two healthy right-handed participants (14 females, mean age 25, range 18–34) with normal or corrected to normal vision and normal hearing provided written informed consent under an experimental protocol approved by the Committee for the Protection of Human Subjects of the Baylor College of Medicine, Houston, TX.
Participants were scanned in a 3 tesla Siemens Trio MRI scanner equipped with a 32-channel head coil at Baylor College of Medicine’s Core for Advanced MRI. Visual stimuli were presented on an MR compatible screen (BOLDscreen32, Cambridge Research Systems, Rochester, UK) placed behind the bore of the MR scanner and viewed through a mirror. Auditory stimuli were presented using high-fidelity MR compatible headphones (Sensimetrics, Malden, MA, USA). Behavioral responses were collected using a fiber-optic button response pad (Current Designs, Haverford, PA, USA) and eye movements were recorded during scanning using the Eye Link 1000 (SR Research Ltd., Ottawa, Ontario, Canada) with a sampling rate of 500 Hz. Stimuli were presented and synchronized with the MR data acquisition using Matlab (The Mathworks, Inc., Natick, MA, USA) with the Psychophysics Toolbox extensions (Brainard, 1997; Pelli, 1997).

Emotional Picture Perception Paradigm

Check if the same lab product or an alternative is used in the 5 most similar protocols

We used a picture perception design with blocks of emotional pictures as stimuli. For a detailed description of the picture perception paradigm see Wehrum et al. (2013 (link)). For this, 30 pictures each in 4 emotional categories (positive, negative, neutral and sexual) were taken from the International Affective Picture System (Lang et al., 2008 ) and the internet. One block consisted of the sequential presentation of five pictures of the same emotional category. Each picture was shown for 3 s. Participants passively viewed the alternating blocks of the four emotional categories. After each block, subjects rated the pictures on three scales (see Subjective ratings). The experiment ran for a total of 15.5 min, starting and ending with the presentation of a white fixation cross for 37.5 s. The paradigm includes sexual stimuli because it is used in a variety of studies from this group, but for our particular hypotheses, they were not relevant and therefore were excluded from analysis. Stimuli were presented using Presentation® software (Version 17.0, Neurobehavioral Systems, Inc., Berkeley, CA, www.neurobs.com) on a monitor at the back of the scanner (resolution: 1920 × 1080 pixels; BOLDscreen 32, Cambridge Research Systems) that the subjects viewed through a mirror mounted on the head coil (visual angle 28 degrees).

MRI Scan Protocol for Diet Initiation

Check if the same lab product or an alternative is used in the 5 most similar protocols

Participants underwent three MRI scans, in the first, second and third week of diet initiation. Because patients were in acute withdrawal and due to scheduling, the MRI in week 1 was performed 4.0 ± 1.7SD days after inpatient admission and after diet initiation (no KD/SA group differences). MRIs were performed on a 3.0 T Magnetom Prisma scanner (Siemens Medical Solutions USA, Inc., Malvern, PA) equipped with a 32-channel head coil. T1-weighted 3D magnetization-prepared gradient-echo (MP-RAGE, TR/TE = 2200/4.25 ms; FA = 9°, 1 mm isotropic resolution) and T2-weighted multi-slice spin-echo (TR/TE = 8000/72 ms; 1.1 mm in-plane resolution; 94 slices, 1.7-mm slice thickness; matrix = 192) pulse sequences were used to acquire high-resolution anatomical brain images. One participant did not complete session 3 due to scheduling problems. For functional MRI, a 32-channel head coil and a standard echo planar imaging (EPI) sequence were used: sequential interleaved acquisition, repetition time 1.5 s, echo time 30 ms, flip angle α = 70°, 64 × 64 pixels in-plane resolution, 36 slices, slice thickness 4 mm, voxel dimensions 3 × 3 × 4 mm³, field of view 192 × 192 mm². Stimuli were presented on a black background under dimmed room lighting using a liquid-crystal display screen (BOLDscreen 32, Cambridge Research Systems; United Kingdom).

We programmed and conducted experimental tasks using PsychoPy version 1.85.2 (Peirce, 2007 (link)). All stimuli were presented on a 32” LCD monitor with an LED backlight intended to display visual stimuli for the fMRI experiments (BOLDscreen 32; Cambridge Research Systems, UK). Participants indicated their responses using two four-button response pads (HHSC-2 × 4-C; Current Designs Inc., Philadelphia, PA, United States).

The Houston site MRI data were acquired with a Siemens TIM Trio Syngo 3T MRI scanner with a 12-channel head coil at the Baylor Imaging Center. Isotropic 3D T₁-weighted structural images were acquired in the sagittal plane (TR = 2170 ms, TE = 3.6 ms, FOV = 256, 1 × 1 × 1 mm voxels, flip angle = 7°, NEX = 1, iPAT = 3) and a turbo-spin echo sequence to collect T₂-weighted structural images (TR = 3200 ms, TE = 410 ms, FOV = 256, 1 × 1 × 1 mm voxels). Isotropic 2D functional images for both tasks were acquired in the axial plane (TR = 2000 ms, TE = 30 ms, flip angle = 79°, 32 axial slices, 3 × 3 × 3 mm voxels, base resolution = 96 × 96, NEX = 1, iPAT = 3). Stimuli at the Houston site were presented on a Cambridge Research Systems BOLDscreen 32 LCD monitor projector at the same resolution as the University of Texas at Austin Biomedical Imaging Center site. Houston participants used the same Optoacoustics headphones and FIU-932 Current Designs button box controller.

An overview of the fMRI pipeline is depicted in Fig. 1b. All subjects underwent structural and resting-state functional MRI on a 3.0T Magnetom Prisma scanner (Siemens Medical Solutions USA, Inc., Malvern, PA) with a 32-channel head coil. To acquire resting fMRI time series a multi-echo, multiband EPI sequence was used: multiband factor = 3, anterior-posterior phase encoding, TR = 891 ms, echo times = 16, 33, and 48 ms, flip angle = 57 deg, 45 slices with 2.9 × 2.9 × 3.0 mm voxels and 520 time points while the participant relaxed with their eyes open (total acquisition time = 8 min). A fixation cross was presented on a black background under dimmed room lighting using a liquid-crystal display screen (BOLDscreen 32, Cambridge Research Systems; UK). The 3D MP-RAGE (TR/TE = 2400/2.24 ms, FA = 8 deg) and variable flip angle turbo spin-echo (Siemens SPACE; TR/TE = 3200/564 ms) pulse sequences were used to acquire high-resolution anatomical brain images with 0.8 mm isotropic voxels field-of-view (FOV) = 240 × 256 mm, matrix = 300 × 320, and 208 sagittal slices.

The task was displayed using Presentation (Version 18.3, build 03.11.16, www. neurobs.com) . The LCD screen presenting (BOLDscreen 32, Cambridge Research Systems) stimuli were visible via a reverse mirror mounted to the participants' head coil and behavioral responses were captured using a button-box (Lumina 3 G Controller, Cedrus Corporation). Picture stimuli contained imagery from the International Affective Picture System (IAPS; Lang, Bradley, & Cuthbert, 2008) . In total, 16 negative and 8 neutral pictures were selected based on IAPS rating scores (see Supplementary Material for valence and arousal normative values).
