Task-fMRI Analysis of Emotion and Gambling

Two different task-fMRI datasets collected from 475 subjects from the Human Connectome Project (HCP) Young Adult study^{6 (link),16 (link)} were used in this paper. The tasks chosen were emotion and gambling. These data are publicly available from the ConnectomeDB database https://db.humanconnectome.org. All data were acquired on a customized Siemens 3 T Connectome Skyra scanner with the following parameters: task-fMRI was obtained with 2 mm isotropic voxels with TR = 720 ms, TE = 33.1 ms. Here emotion processing task was carried out with two runs of 2:16 min with 176 frames per each run. Gambling task was continued for 3:12 mins with 253 frames per run for two runs^{75 (link),76 (link)}.

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.
