The Human Brain Physiology and Stimulation Laboratory studies the mechanisms of motor learning and develops interventions to modulate motor function in humans. The goal is to understand how the central nervous system controls and learns to perform motor actions in healthy individuals and in patients with neurological diseases such as stroke. Using this knowledge, we aim to develop strategies to enhance motor function in neurological patients.
To accomplish these interests, we use different forms of non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), as well as functional MRI and behavioral tasks.
The Marsh Lab studies stroke treatment, recovery and risk identification. The Marsh Lab created the Hemorrhage Risk Stratification (HeRS) score to predict hemorrhagic transformation in patients treated with anticoagulants. Currently, the Marsh Lab is using magnetoencephalography (MEG) to investigate how strokes impact higher level cognitive processes. Additional research in the lab focuses on treatment options for reversible cerebral vasoconstriction syndrome (RCVS).
