Low Intensity Focused Ultrasound for Neural Mapping

This trial explores how the brain responds to low-intensity focused ultrasound (LIFU), a non-invasive technique using sound waves to stimulate the brain. The researchers aim to understand brain circuit connectivity in real-time by observing reactions in patients with implanted electrodes. The trial targets adults hospitalized for epilepsy or neuropsychiatric conditions who have undergone or will undergo electrode implantation surgery. Participants must be stable in their medical condition and able to follow instructions in English. This research could help map brain activity and improve future treatments for neurological conditions. As an unphased trial, it offers a unique opportunity to contribute to groundbreaking research that could enhance neurological treatments.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Research has shown that low-intensity focused ultrasound (LIFU) is generally safe and well-tolerated. Studies have found that LIFU provides a safe and non-invasive method to influence brain activity. In one safety study, even at high intensity, LIFU proved safe for patients recovering from strokes. Another study confirmed that the intensity of LIFU used remained within the FDA's safety limits, posing a "non-significant risk."

Low Intensity Focused Ultrasound (LIFU) is unique because it offers a non-invasive approach to neural mapping, which could transform how we understand and treat neurological conditions. Unlike traditional methods that might require surgery or external devices, LIFU uses sound waves to precisely target and map brain activity without the need for incisions. Researchers are excited about this treatment because it has the potential to provide a safer, more accurate way to explore brain functions, leading to better diagnosis and treatment plans for patients.

Research has shown that Low Intensity Focused Ultrasound (LIFU), which participants in this trial will receive, can safely alter brain function. Studies suggest it might help treat conditions like depression and chronic pain by targeting specific brain areas. For example, one study found that LIFU reduced a brain signal related to pain by 38.1%. This indicates that LIFU can affect brain function without surgery. Although more research is needed, these early results suggest it could effectively change brain activity.¹⁶⁷⁸⁹
