Individual Brain Charting: HCP Language task

This dataset contains functional magnetic resonance images (fMRIs) of 12 subjects performing HCP Language task that was used as a localizer of brain regions involved in semantic processing. It was adapted from a study dedicated to exploring the particular role of the anterior temporal lobe (ATL) on semantic integration. The paradigm comprised two categories of blocks: (1) story blocks and (2) math blocks. Math blocks served as a control condition in this context, since it is likely to involve both auditory processing and attentional demands. Both type of blocks exhibited auditory stimuli in short epochs, which in turn finished with a final question followed by two possible answers. During story blocks, in which participants were presented with Aesop’s fables, the final question targeted the topic of the story. Conversely, math blocks showed arithmetic problems for which the correct solution must be selected. The response was provided after the two possible options were displayed, through pressing the corresponding button of the response box. The difficulty levels of the problems, presented for both categories, were adjusted throughout the experiment, in order to keep the participants engaged in the task and, thus, ensure accurate performances. The task was composed by eleven blocks per run. For the first run, six story blocks and five math blocks were interleaved, respectively. The reverse amount and order of blocks were used during the second run. The number of trials per block varied between one and four. Nevertheless, it was assured that both block categories matched their length of presentation at every run. There was a cue during two seconds at the beginning of each block, indicating its category. The duration of the trials within a block varied from ten to thirty seconds. Finally, the presentation of the auditory stimuli was always accompanied by the display of a fixation cross on the screen throughout the entire run.
