Mechanisms Evaluating Striatal Systems Imaging: LIFU Effects & Outcomes

Brief Summary

Individuals with schizophrenia often experience persistent auditory hallucinations despite treatment with antipsychotic medications. Research suggests that abnormal communication between the striatum and the auditory cortex contributes to hallucinations. This first-in-human, proof-of-concept Phase 1 study will evaluate the safety, feasibility, and preliminary effects of repeated-session low-intensity focused ultrasound (LIFU), a non-invasive neuromodulation technique targeting the striatum. The study will examine whether LIFU can safely modulate brain circuits involved in hallucinations, reduce abnormal communication between the striatum and auditory cortex, and improve auditory hallucination symptoms.
