Ultrasonic potentiation of ketamine neuromodulation

Kanchan Sinha Roy, Payton J. Martinez, Sedona N. Ewbank, Kenneth Shinozuka, Mahaveer Prasad Purohit, Yun Xiang, Raag D. Airan

This paper shows that focused ultrasound enhances ketamine's neuromodulatory effects, with localized delivery via SonoKet achieving greater neurotransmitter changes at lower doses.
