Vascular Neurology Research

Research Description

The goal of our research is to help people with neurologic disorders, especially those who are severely paralyzed from stroke, spinal cord injury, traumatic brain injury, or ALS. Our research centers around using neural prosthetics, i.e., human machine interfaces, to help restore or replace function of the injured nervous system. We have developed a myoelectric interface for neurorehabilitation training (MINT) to help people with stroke regain function in their arms. The MINT uses electrical muscle signals to control a cursor in customized video games. This enables them to improve coordination between the muscles.

Brain-machine interfaces (BMIs) offer the capability to “decode” brain signals and use them to control computer cursors, prosthetic limbs, or haptic feedback devices. We are investigating the possibility of using BMIs to help rehabilitate brain function by driving plasticity. We study this in humans with traumatic brain injury. In addition, we are investigating the potential to decode a person’s intended speech directly from his or her brain and using this to restore communication to people who have lost it due to severe paralysis. We also use this powerful paradigm to study the underlying relationship between different types of brain signals, for example, the relationship between field potentials (summed from many neurons in the network) and action potentials of individual neurons.

Research Description

Our research program is directed at understanding neurovascular function in health and disease. Specifically, we have been studying the association between cerebral blood flow regulation, structural changes in the brain and the clinical outcomes of acute and chronic cerebrovascular injury. In acute neurovascular disorders, we have validated several novel indices of cerebral blood flow regulation which can now be used to predict the development of vasospasm in subarachnoid hemorrhage and hematoma expansion in patients with intraparenchymal hemorrhage. The availability of these early non-invasive biomarkers will have a significant impact on early interventions to improve outcome in patients with subarachnoid and intraparenchymal hemorrhage. Similarly, in chronic neurovascular disorders associated with aging and neurodegeneration, we have been examining the contribution of vascular disease to mobility impairment and cognitive decline. We have shown that our non-invasive biomarkers of vascular function are strongly associated with cerebral small vessel disease as well as motor and cognitive impairment. Our goal is to expand these studies to include other neurological disorders such as stroke, pre-eclampsia, traumatic brain injury and dementia. Having non-invasive, real-time measure of neurovascular function which can predict clinical outcome in the early phases of brain injury will have significant implications on clinical trials and therapeutic targets designed for the treatment and prevention of these various acute and chronic neurovascular injuries.
