美国科学院院士, 麻省理工学院Robert Desimone教授对此工作进行了点评:
The development of methods to use light to control the firing of neurons in the brain has revolutionized neuroscience research. But light based methods generally require a probe implanted in the brain to deliver the light. If one could use a noninvasive source of energy, such as ultrasound, to control neurons, this would have major research and clinical applications. The results of Jia Ye et al with ultrasound look extremely promising, and I am sure they will stimulate more research to test the use of ultrasound in many neural applications, both basic and clinical.
