Trial summary

The purpose of this study is to understand how the sensory and motor areas of the brain work together to keep a person's hand movements accurate (sensorimotor learning). The investigators hope this information may be useful one day to improve rehabilitation techniques in patients with brain lesions. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 45 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Ages of 18-45 years old
  • Right-handed.
  • Free of Covid symptoms in week preceding testing.

Who cannot join

  • metallic, mechanical, or magnetic implants;
  • are claustrophobic, or are unable to remain still for long periods of time;
  • use an intra-uterine device (IUD) whos MR compatibility has not been established.
  • Women who are pregnant or think they might be pregnant will also be excluded, as effects of fMRI on the unborn are not known.

  • Investigators will also exclude subjects who do not have normal vision, or corrected-to-normal vision with contacts, or the imaging center does not have a pair of MRI compatible glasses that fits their prescription.
  • investigators will invite subjects to reschedule if they have any of the common Covid symptoms within the last week and if they haven't been fully vaccinated or obtained a negative Covid test within the past 4 days. If they don't believe they can meet these criteria on another date, they will be excluded.
  • After giving their consent, participants may be excluded during the study if they are unable to perform the tasks or follow instructions.

About this study

The purpose of this study is to understand how the sensory and motor areas of the brain work together to keep a person's hand movements accurate (sensorimotor learning). The investigators hope this information may be useful one day to improve rehabilitation techniques in patients with brain lesions.

Read the detailed description

Human perception of hand position is multisensory. The brain can estimate it visually, from an image on the retina, and proprioceptively, from receptors in the joints and muscles. The sensory inputs determining these percepts are subject to changes in environmental factors (e.g., lighting) and internal factors (e.g., movement history). Multisensory integration of visual and proprioceptive estimates gives us flexibility to cope with such changes. For example, washing dishes with the hands immersed in water creates a spatial misalignment between vision and proprioception, as water refracts light. The brain resolves this conflict by realigning visual and/or proprioceptive estimates of hand position, and also by adjusting motor commands (visuomotor adaptation). The neural basis of these adaptive processes is poorly understood. The purpose of this study is to find out if multisensory and visuomotor learning are accompanied by changes in resting state connectivity between sensory regions of the brain and other areas.

The first session is a familiarization session for functional magnetic resonance imaging (fMRI) and the behavioral task, and is expected to last 30-40 minutes. Subjects will first fill out screening forms to confirm the answers given during the initial screening, and the Edinburgh handedness inventory to quantify their handedness. If subjects are still eligible, subjects will lie in a mock scanner and perform the functional task: Subjects will have their left index finger taped to a wooden stick, and an experimenter from the team will manipulate the finger with the stick outside of the scanner. Subjects will respond to the different movements by pressing buttons with their right hand. Subjects will also be introduced to the behavioral task, which is performed at an apparatus in the room next to the scanner: Subjects sit in front of a touchscreen and point to targets seen in a mirror.

If subjects are interested in moving on to the main session at this point, the main session will be scheduled.

The main session will take about 2 hours. Subjects will first fill out the MR safety screening form. Subjects will then perform some practice trials of the behavioral task to remind the subject of the task. This will be followed by the first resting state scan (12 min), a 20-30 minute baseline block of the behavioral task (no learning), a second resting state scan (12 min), the 20-30 minute learning block of the behavioral task, and a third resting state scan (12 min). Finally, the subject will do the functional task in the scanner (same as familiarization session, 12 min. total) and an anatomical scan (~6 minutes). The session will conclude with some questions about the subject's subjective experience of the procedures.

What is being measured

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

  1. Resting-state PMv-M1 Functional Connectivity (Fisher Z-transformed Correlation)

    Brain activity was measured during a 12-minute resting-state functional magnetic resonance imaging (fMRI) scan. Resting-state functional connectivity between the ventral premotor cortex (PMv) and primary motor cortex (M1) was quantified as the Pearson correlation coefficient between the mean blood-oxygen-level-dependent (BOLD) time series extracted from anatomically defined PMv and M1 regions of interest. Correlation coefficients were Fisher z-transformed to improve normality. For each participant, connectivity values were averaged across all scans acquired during the main session. The outcome measure is the mean Fisher z-transformed correlation value (unitless). Numbers range from -1 (opposite activity in the two regions) to 1 (similar activity in the two regions), with 0 implying no relationship between the two regions.

    Measured: 3 scans during the main session (2 hours)

  2. Weighting of Vision vs. Proprioception

    Measured by comparing where subjects point on the touchscreen when they are estimating visual vs. proprioceptive targets. A person who relies only on vision would have a weighting value of 100%. A person who relies only on proprioception would have a weighting of 0%. A value of 50% would imply equal reliance on vision and proprioception.

    Measured: Measured during the main session (2 hours)

Questions about this trial

What is this clinical trial studying?

A study testing Perceptual learning in people with Basic Science, run by Indiana University at 1 site in United States.

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 9 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: finished, as of the sponsor's last update on 28 Jan 2026. 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 United States. 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?

Yes. Results are posted in the registry (first posted 28 Jan 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Resting-state PMv-M1 Functional Connectivity (Fisher Z-transformed Correlation) (time frame: 3 scans during the main session (2 hours)). The study lists 2 primary outcomes in all. 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 28 Jan 2026.
