MRI Protocol for Behavioral Response

MRI data were acquired on a Siemens Trio 3T scanner (Malvern, PA) using a
standard quadrature head coil. Functional images were collected using a
T2*-weighted gradient-echo echo-planar image (EPI) sequence providing full head
coverage (TR = 2320ms, TE = 25ms, flip angle = 60°, FOV
= 225 × 225, 3.5mm isotropic voxels [no gap], 40 axial
slices, oblique axial prescription parallel to AC-PC plane). Stimuli were back-projected
using E-Prime presentation software (Psychology Software Tools Inc., Pittsburgh, PA)
onto a translucent screen, viewed via a coil-mounted periscopic prism system.
Participants' behavioral responses were collected via fiber optic button box,
with two possible responses for both AF and AH conditions (‘same’ or
‘different’ identities). T1-weighted 2D anatomical images with the same
slice prescription as the EPI data (TR = 300ms, TE = 2.43ms, flip angle
= 60°), and a T1-weighted 3D anatomical MPRAGE volume (TR =
2530ms, TE = 3.66ms, TI = 1100ms, flip angle = 7°, 1mm
isotropic voxels), were acquired during the same session, for standard-space image
registration.

Examining Interpersonal Dynamics in EEG

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experiment was conducted in two sessions (A and T conditions). For the A condition, EEG recordings were collected from participants sitting isolated in a dimly lit EEG laboratory. For the T condition, two participants sat together in the same EEG lab. Participants sat in comfortable chairs approximately 100 cm away from, and at eye level with a 40 × 30 cm IIyama PC computer screen. In the T condition, the participants sat beside each other, both facing the computer screen. The order of the A and T conditions was counterbalanced. Participants interacted with each other during the installation of the EEG caps and in the period between the A condition and T condition sessions.
In both conditions, participants were shown a white fixation cross for 2 min, which was presented centrally on the computer screen using E-prime presentation software (Psychology Software Tools, Inc.). To reduce the number of EEG artifacts caused by eye movement, participants were instructed to relax and reduce blinking and other ocular movements during the experimental sessions.

Neuroimaging Scene Perception Protocol

Stimuli for this experiment were images of scenes that had previously been used in a neuroimaging study (Kravitz et al., 2011 (link)). The stimulus set comprised 96 individual, highly detailed, and diverse real-world scene images from 16 basic-level scene categories (churches, concert halls, hallways, living rooms, forest canopies, canyons, caves, ice caves, cities, harbors, highways, suburbs, beaches, deserts, hills, mountains), with six exemplars within each category, spanning the following three diagnostic scene properties: spatial expanse (open, closed; the spatial boundary of the scene); relative distance (near, far; distance to the nearest foreground objects); and naturalness (or semantic content; man-made, natural; Fig. 2a, full stimulus set). The images were presented full screen, subtending 27º of visual angle, at a viewing distance of 75 cm. The stimuli were presented using E-Prime presentation software (Psychology Software Tools).

Afternoon Tryptophan Restriction Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Each participant completed one experimental visit of 150-min taking place in the afternoon after a 2 h food abstention period. On the experimental day, participants were requested to avoid food and beverages from a given list of products high in TRP, including products with meat, fish, soya, milk, egg or seeds. Compliance to the study restrictions was verified from a self-report prior to the experiment visit. The experiment was conducted in a sound-attenuated, shielded recording booth and was fully computerized using E-Prime ® presentation software (Psychology Software tools, Sharpsburg, PA USA). Participants received the instructions from a computer screen and performed the required tasks using either a response box or a mouse pad. The study procedure is described in Table 2.

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.
