Brief Summary

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

Our proposed study employs a novel approach to determine the clinical and functional imaging effects of brainstem neuromodulation, with an investigational study device, on illness awareness in schizophrenia - a significant contributor to medication non-adherence and poor treatment outcomes, and arguably the most treatment resistant manifestation of the disorder.

The study device under investigation provides a safe and non-invasive method of brainstem stimulation that will be used in conjunction with a neuroimaging biomarker to measure brain changes associated with treatment and illness awareness.
