Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to test the effects of brief, low-intensity transcranial focused ultrasound (TUS) on electrophysiological, behavioral, and cognitive markers related to anxiety disorders.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will test the effects of TUS on self-reported and clinical anxiety states in healthy participants and in those with diagnosed anxiety disorders. Participants in these studies will receive pulsed TUS to the brain regions of interest. We will test whether multiple doses of TUS lead to larger reductions in mental states related to anxiety in comparison to a single dose of TUS.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experiment 1

The study will consist of 2 groups. A: no current diagnosis of anxiety or other psychological disorders. B: Current diagnosis of anxiety disorder. Results will be analyzed within and between groups. Participants will answer standardized questionnaires and other similar validated psychological scales. An ultrasound transducer will be placed on their head aimed at the brain region of interest. EEG data will be collected throughout the process. After this process, participants will answer a set of post experiment questions.

Group Type EXPERIMENTAL

Gen0b

Intervention Type DEVICE

The ultrasound will be administered to the brain region of interest.

Experiment 2a

Current diagnosis of anxiety disorder is required. Participants will receive an MRI. Participants will answer standardized questionnaires and other similar validated psychological scales. An ultrasound transducer will be placed on their head aimed at the brain region of interest. EEG data will be collected throughout the process. After this process, participants will answer a set of post experiment questions

Group Type EXPERIMENTAL

Gen0b

Intervention Type DEVICE

The ultrasound will be administered to the brain region of interest.

Experiment 2b

Experiment 2b will expand on Experiment 2a protocol with multiple visits. Each visit will consist of the same activities as Experiment 2a.

Group Type EXPERIMENTAL

Gen0b

Intervention Type DEVICE

The ultrasound will be administered to the brain region of interest.
