Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
NightPP
Participants of the NightPP will be subjected to one MRI session and two MEG recording sessions: the first one before a physical practice session of the two motor tasks investigated in the study, and second MEG session right after practice.
Imagery and Sleep questionnaires
Participants complete a motor imagery questionnaire to assess their ability to form vivid mental images, as well as sleep questionnaires to control the quality of their sleep
MEG recordings (pre-test)
Participants of the Day group perform two motor tasks (a finger sequential motor task and an adaptation motor task using a trackball) in the MEG, during a pre-test (Day 1 - 9h).
Task 1: Participants perform an 8-digit motor sequential task where each finger (except the thumb) is used twice. Performance is assessed by using a 4-keys keyboard. Participants are required to keep their fingers on the keys to minimize amplitude are instructed to tap the sequence as few errors as possible Task 2: Participants perform a motor adaptation task requiring scrolling a trackball to superimpose a geometric shape on another one, strictly similar but presented from another angle, as fast as possible.
Practice session
Participants of the Day group perform a block of motor imagery practice of the two motor tasks.
MEG recordings (Post-test)
Participants perform the two motor tasks in the MEG (post-test, strictly similar to the pre-test)
MRI
The registration of the brain anatomy of each participant will be done by MRI 3D / T the week before the first experimental session.
NightMI
Participants of the NightMI will be subjected to one MRI session and two MEG recording sessions: the first one before a motor imagery practice session of the two motor tasks investigated in the study, and second MEG session right after practice.
