Individual Brain Charting: ARCHI emotional

This dataset contains functional magnetic resonance images (fMRIs) of 12 subjects that investigates cognitive-emotional processes on perception of faces and expressions. The paradigm was arranged in blocks that comprised sets of trials. Two categories of conditions can be highlighted from the paradigm: (1) the face-task category and (2) the eye-task category. Both categories involved self-reply according to the stimulus presented at every condition. The face-task category consisted in the presentation of human faces, whereas the eye-task category was dedicated to images representing human eyes. For the face-task category, two conditions corresponded to evaluation of gender and trustworthiness of the human faces. In the eye-task category, the two homologous conditions referred to gender and emotion-expression evaluation. The task concerning emotion expression in the latter category was in accordance with a cue given immediately before the image display. Besides, there was also a baseline condition, common to both categories, showing a grayscale grid image that may be tilted or not. To achieve the intended goal of this condition, a mental assessment about the orientation of the image had to be performed. The task consisted of twelve blocks per run, and every block comprised between two and four trials. The order of trials presentation was pseudorandomized for the session, but fixed for all participants. The trials lasted about 6.3 seconds. A fixation-cross period of approximately one second was presented between blocks.
