Study Details

Brief summary:

Focused ultrasound at low intensities is a form of neuromodulation with high spatial resolution that can be applied invasively or non-invasively using acoustic energy to affect neuronal activity. The purpose of this study is to better understand the effects of low intensity focused ultrasound (FUS) on the central nervous system. Specific patient populations within UVA health system are undergoing treatment that provide unique opportunities to study these effects.

Interventions and Outcome Measures

Arms

experimental: Patients receiving Craniotomy

Patients receiving an awake or asleep craniotomy for brain tumors and/or epilepsy will undergo a brain mapping procedure using electrical stimulation as a part of their normal care. The research procedures will duplicate this mapping with an invasive Focused Ultrasound mapping.

experimental: Epilepsy Patients

Patients undergoing long term monitoring for epilepsy will receive a non-invasive form of Focused Ultrasound stimulation which will be measured by their EEG cap and intracranial electrodes which are a part of their normal care.

experimental: Tremor Patients receiving FUS

Patients undergoing high intensity FUS treatment for tremor will be asked to wear a research provided EEG cap while undergoing a non-invasive low intensity Focused Ultrasound research procedure and changes in their tremor will be monitored.

experimental: Tremor Patients receiving DBS

Patients undergoing Deep Brain Stimulation (DBS) treatment for tremor will receive a non-invasive Focused Ultrasound stimulation observed through their newly implanted electrode.

experimental: Patients receiving Spinal Surgery

Patients receiving a spinal surgery will undergo a spinal stimulation using electrical stimulation as a part of their normal care. The research procedures will duplicate this with an invasive Focused Ultrasound stimulation.

Interventions

Focused Ultrasound

Low intensity focused ultrasound is sound energy stimulation at a low intensity of 1-30 W/cm2

Primary outcome measure

  • Electrophysiological Changes as a result of Ultrasound [ Time Frame: baseline, immediately after ultrasound (same day, approximately 5-10 minutes after baseline) ]
