Brief description of study

The current study presents a unique opportunity to measure the immediate neural responses to brief, non-therapeutic transcranial low-intensity focused ultrasound (LIFU) pulses using intracranial electrodes. By recording time-locked signals in local and distant brain regions we can characterize circuit connectivity in real-time. We will use adult patients undergoing intracranial electrophysiological monitoring in an inpatient setting as our targeted population.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Medical Research
  • Age: 21 years - 75 years
  • Gender: All

Inclusion:

  1. Patients who received (or are scheduled to receive) intracranial electrode implantation surgery as part of standard clinical care or as participation in an ongoing research study for the treatment of epilepsy and/or neuropsychiatric conditions at Pennsylvania Hospital (PAH) or Hospital of the University of Pennsylvania (HUP).

  2. Adult patients, 21 to 75 years of age

  3. Patients considered to be in a stable medical condition, in the opinion of the PI

  4. Patients who are able to demonstrate comprehension of instructions in the English language, in the opinion of the PI

  5. Patients who are able to provide informed consent and fully comply with all study requirements, in the opinion of the PI

Exclusion:

  1. Patients with chronic alcohol abuse history

  2. Patients with additional implanted devices, such as an aneurysm clip, large cranial plates or mesh that may intersect with ultrasonic beam path

  3. Open scalp wounds, infection or dermatologic condition that preclude safe placement of ultrasound transducer

  4. Intracranial mass lesion with significant mass effect near intended beam path

  5. Patients who are pregnant at the time of screening or patients who get pregnant during the course of the study

  6. Patients with any past or present medical condition, disease, disorder, or injury that, in the opinion of the PI, may reduce or hinder the participant’s ability to fully comply with all study requirements or may impact, compromise, or affect the integrity of the data or the results of the study
