About

This study aims to evaluate three different transcranial magnetic stimulation protocols and their impact on motor system neurophysiology and skill learning.

Full description

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation method that induces long-term changes in connections between neuronal networks. This and the ability to activate the whole motor system allows the use of TMS to facilitate motor recovery. The motor system has different excitatory states associated with ongoing mu oscillation. Here, the investigators will monitor brain mu oscillations in real-time non-invasively using electroencephalography and modulate the function of the motor system. The investigators will test the impact of three different TMS protocols on motor system neurophysiology and skill learning. These data will provide novel understanding needed to improve TMS approaches for individuals requiring motor rehabilitation.

45 participants in 3 patient groups

Single-pulse TMS over the primary motor cortex

Experimental group

Description:

We will administer single-pulse TMS to the primary motor cortex while measuring motor responses and just before a skill-learning task.

Treatment:

Device: Transcranial Magnetic Stimulation (TMS)

Paired-pulse TMS over the primary motor cortex

Experimental group

Description:

We will administer paired-pulse TMS to the primary motor cortex while measuring motor responses and just before a skill-learning task.

Treatment:

Device: Transcranial Magnetic Stimulation (TMS)

Sham TMS over the primary motor cortex

Sham Comparator group

Description:

We will administer sham TMS to the primary motor cortex while measuring motor responses and before a skill-learning task.
