Deskripsi

Low-intensity ultrasound can be used for neuromodulation in vivo, but it has poor spatial confinement and can result in unwanted cochlear pathway activation. Here the authors use the optoacoustic effect to generate spatially confined ultrasound waves to activate neurons within a 500 μm radius in the mouse brain.
