Individual Brain Charting: HCP Working Memory task

This dataset contains functional magnetic resonance images (fMRIs) of 12 subjects performing HCP Working Memory (HCP WM) task that was adapted from the classical n-back task to serve as functional localizer for evaluation of structures involved in working memory (WM). The paradigm included two categories of blocks, namely the “0-back” and “2- back” WM-task blocks. They were both equally presented within a run. A cue was always displayed at the beginning of each block, indicating its block type. Blocks were formed by sets of events, during which pictures of faces, places, tools or body parts were shown on the screen. One block was always dedicated to one specific category of pictures and the four categories were always presented during every run. The task was constituted by sixteen blocks per run, eight per n-back category. Besides, there were four pairs of blocks per visual category. The order of the blocks, regardless of their category and corresponding class of pictures, was pseudo-randomized for every run, but fixed for all participants. A fixationcross period of fifteen seconds was introduced between some blocks. All blocks contained ten trials; they were initiated by a cue during 2.5 seconds. Trials included in turn the presentation of a picture for two seconds and a very short fixation-cross period for half of a second; the total duration of one trial was thus 2.5 seconds.
