fMRI - Self-concept Task

The fMRI - Self-concept Task measures brain activity during the Self-concept Task, in which children are asked whether certain negative and positive traits fit them.

The Self-concept Task functional runs were acquired using a T2*-weighted echo-planar imaging (EPI) technique. To ensure stable imaging, the first two volumes, known as dummy volumes, were discarded initially to allow for the equilibration of T1 saturation effects. The imaging parameters used remained constant throughout the waves. The acquired volumes covered the entire brain with a field of view (FOV) measuring 220 mm in the anterior-posterior (ap) direction, 220 mm in the right-left (rl) direction, and 111.65 mm in the foot-head (fh) direction. The imaging protocol employed a repetition time (TR) of 2.2 seconds, representing the time between acquiring consecutive image volumes. The echo time (TE) was set to 30 milliseconds, which indicates the time it takes for the MRI signal to be measured after the radiofrequency pulse. A flip angle (FA) of 80° was used, and the data was acquired sequentially in 37 slices with a voxel size of 2.75 mm x 2.75 mm x 2.75 mm.
