Our laboratory's major focus is on the development of novel methods to treat brain injury, particularly the type of brain injury that leads to epilepsy. We are currently working to identify mechanisms by which noninvasive brain stimulation can stop or prevent seizures.
We have adapted methods for transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) to rodents and to in vitro brain slice preparations. These methods have in common the capacity to safely induce durable changes in neuronal activity. Limited experience with human patients, including those treated at Children's Hospital Boston, shows that TMS and tDCS have realistic prospects in suppressing seizures. Yet whether these techniques can prevent the onset of epilepsy after various forms of brain injury has not been tested. To characterize the cellular mechanisms by which TMS and tDCS exert their effect, and ultimately to optimize their clinical efficacy, we have adapted these techniques to rat epilepsy models, including one model of traumatic brain injury (TBI).
To determine how best to match the cellular changes induced by noninvasive brain stimulation those of brain injury and epilepsy, we are studying the molecular changes associated with TBI in rats. A second major focus has grown out of this work: testing novel pharmaceutical approaches to prevent brain injury and seizures after TBI.
In parallel to our laboratory experiments, we have ongoing clinical projects aimed to further develop techniques for noninvasive brain stimulation, particularly TMS, as diagnostic and therapeutic tools in child neurology.
