Datasets
BIDS
All functional and anatomical data has been formatted in BIDS, for more information visit the Brain Imaging Data Structure documentation site. Some of the files do not follow the main BIDS convention:
Anatomical sequences with multiple contrasts are following BEP001.
Note that BIDS session names have no meaning apart from being data acquired in the same session. The number of runs, the tasks and their order within each session will not match from one participant to another. Note that a few session indices are skipped if the whole session was discarded for various scanning issues.

Participants
<Description of sample demographics>
Exclusion criteria included visual or auditory impairments that would prevent participants from seeing and/or hearing stimuli in the scanner and major psychiatric or neurological problems. Standard exclusion criteria for MRI and MEG were also applied. Lastly, given that stimuli and instructions are presented in either English or French, all participants had to identify their language of choice.
Neuroventure
The Neuroventure dataset is a 5 year longitudinal neuroimaging dataset, accompanied by behavioral and cognitive information acquired at each year. Participant behavioral information is acquired at each of the 5 years. The following tasks are described below

anat
The anatomical dataset includes longitudinal anatomical images of the brain acquired 3 times over the 5 year span of the study. The primary intended use of this dataset is to … . Many quantitative measures of brain structure can also be derived and included in analyses, such as <types of anatomically derived metrics>.
The MRI sequences are described in more detailed in Brain_anatomical_sequences, including pdfs of the Siemens exam cards.
All images covering the face were anonymized by zeroing the data in the face, teeth and ears regions with a custom mask warped from the MNI space based on a linear registration of the T1w brain MRI series. This defacing script is available here.
