Modulating Movement Intention Via Cortical Stimulation in Healthy Subjects and Patients With Psychogenic Movement Disorders and Non-epileptic Seizures
NYU Langone Health
Summary
The purpose of this protocol is to learn about movement intention and volition. To improve such knowledge, investigators will conduct sub-studies using multiple non-invasive methodologies. These results could provide preliminary data for subsequent studies evaluating local and global efficacy of plasticity-inducing treatments for PMD symptoms.
Description
This study will: * Explore effects of TMS and tDCS on movement intention. * Discern the neural activity underlying modulation of movement intention with neuroimaging recording. * Identify brain stimulation's effect in patients with psychogenic tremor and non-epileptic seizures. * Technical development of new experimental paradigms and data analysis methods. * Data collection for hypotheses development.

Interventions
- DeviceSham TMS3 stimulation
half of the subjects will receive sham stimulation first
- DevicerTMS of left or right angular gyrus (AG) or frontal cortex (FC)
Half of the subjects will receive active stimulation first; A subject may receive either TMS or tDCS stimulation, but not both, over the course of the sub-study.
- DeviceAnodal tDCS of left or right AG or FC
Half of the subjects will receive active stimulation first; A subject may receive either TMS or tDCS stimulation, but not both, over the course of the sub-study.
