SLeep and IMagery Correlates (SOMMEIL-IMAGERIE)

Summary

This study is designed to determine the neural networks underlying the sleep-related motor consolidation process following motor imagery practice. While beneficial effects of sleep are expected for sequential movement but not for adaptation motor tasks, the corresponding neuroanatomical correlates have not yet been investigated when participants acquired the motor tasks through mental practice. Data should substantially promote how designing motor imagery interventions targeting (re)learning and/or motor recovery in patients suffering from motor disorders.

Conditions

• Healthy

Interventions

OTHER

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

OTHER

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.

OTHER

Practice session

Participants of the Day group perform a block of motor imagery practice of the two motor tasks.

OTHER

MEG recordings (Post-test)

Participants perform the two motor tasks in the MEG (post-test, strictly similar to the pre-test)

OTHER

MRI

The registration of the brain anatomy of each participant will be done by MRI 3D / T the week before the first experimental session.
