 This paper proposes a novel ultrasound neuromodulation system that can accurately target multiple brain regions. The system uses acoustic holography to compensate for skull aberrations, as well as a phase conjugation mirror and MEMS technology to create a lightweight, portable device. The system was tested in freely moving mice and successfully demonstrated the ability to target multiple brain regions simultaneously. This system has the potential to revolutionize the field of neuroscience by providing researchers with a powerful tool for studying the effects of ultrasound neuromodulation on the brain.
