Brief 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.
Detailed 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.
