About this study

Official title: Acquisition and Retention of Motor Memories in Adults and Typically Developing Children. IRM f Study

Our motor skills require motor memories without which our behavior is only reflexes and stereotypies. The way which these memories form in the human brain constitute therefore a major challenge for neuroscience research. Some a lot of evidence suggests that any new motor skills is acquired in the cerebellum and then persisted in the cortex. This vision seems however caricature, the formation of memories motor probably requiring complex remodeling of cortico-cerebellar networks. The MotorMemo project aspires to better understand this remodeling, by testing more specifically the hypothesis of cerebellar weakening and strengthening cortical as a substrate for the formation of motor memories. A longitudinal study using a sensorimotor adaptation protocol, fMRI as well as a developmental perspective is proposed to verify this hypothesis.

Read the detailed description

A fundamental human faculty is that of adapting our motor behavior to changing environmental conditions. This faculty is comparable to an apprenticeship adaptive during which the individual updates, on a trial and error basis, the correspondence between sensory inputs and the resulting motor commands. Once updated, these correspondences or internal models allow the individual to produce a behavior precise and reproducible motor. The issue of model acquisition and retention internal movement is therefore central to our understanding of motor control. Relatedly, this question constitutes a gateway to a more comprehensive understanding of the mechanisms of learning and procedural memory.

The MotorMemo project therefore aims to study the formation of internal models of movement in the human brain, with the particularity of being interested in the correlates cerebral processes of acquiring and retaining an internal model of visuomotor transformation in healthy children (8-12 years) and adults.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Functionel MRIOther

    During the activation fMRI sequences, the subject will perform target pointing tasks, that is to say that he will have to reach, by controlling a cursor using a non-magnetic joystick, targets projected onto a display screen. In each of the pointing tasks he will have to reach the target as quickly and as precisely as possible, and stay in the center of it for a long time times reached.

Study groupRoleWhat they receive
AdultsExperimentalThe subject will be subjected to 2 functional MRI sessions spaced 3 days apart Each session will be composed of the same MRI sequences without injection, namely an anatomical exploration sequence followed by sequences of functional exploration of rest and activation (while the subject performs the task motor). The resting functional exploration sequences will frame (1 before, 1 after) the functional activation sequence.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate, in adults and children, whether the acquisition and retention of a new internal movement pattern are linked to the activation of a large cortico-cerebellar network ladder.

    Change in cerebellar activation and cortical induced by the visuomotor adaptation task compared to a task motor control not requiring adaptation

    Measured: 3 days

Questions about this trial

What is this clinical trial studying?

A study testing Functionel MRI in people with Memory, run by University Hospital, Grenoble at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Fabien CIGNETTI, phD (04 76 63 71 10 ext. 0033, fabien.cignetti@univ-grenoble-alpes.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate, in adults and children, whether the acquisition and retention of a new internal movement pattern are linked to the activation of a large cortico-cerebellar network ladder. (time frame: 3 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2020.
