SLeep and IMagery Correlates (SOMMEIL-IMAGERIE)

September 9, 2025 updated by: Hospices Civils de Lyon

Neurophysiological Correlates of Sleep Motor Consolidation Following Motor Imagery Practice

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.

Experimental: 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.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Evidence of MEG correlates of sleep motor consolidation (day 1)
Time Frame: Day 1 at 19h00 [post-training] (Groups 1, 2 and 3) OR Day 1 at 9h00 [post-training] (Group 4)
The investigator will use Single Aperture Magnetometry, i.e. a minimum variance beamformer mapping the spatial distribution of event-related desynchronizations and synchronizations within a predetermined frequency domain (Beta oscillations 15-35 Hz). The time course of MEG Beta power will be considered, and Granger causal connectivity analyses will be performed to investigate relationships between cortical motor regions.
