Article published in IEEE Transactions on Biomedical Engineering
Tom's article shows that the human peripheral nervous system is more effectively stimulated with ultrasound at low frequencies. This result also bolsters the notion of mechanical effects of ultrasound on excitable cells.

Acoustic properties across the human skull
This information led to the development of a new device, "Diadem", that delivers focused ultrasound into specified deep brain circuits of humans at a controlled dose. This controlled approach safely delivers into the desired circuits much higher ultrasound intensities than previously possible, thus increasing the efficacy and reproducibility of ultrasound-based interventions.

Preprint of sonic neurostimulation in non-human primates
We found that transcranial ultrasound is capable of modulating neurons to the extent of biasing choice behavior of non-human primates. A demonstration of tangible, brain-region-specific effects on behavior of primates constitutes a critical step toward applying this noninvasive neuromodulation method in investigations of how specific neural circuits are involved in specific behaviors or disease signs.

Research paper published in the Journal of Neuroscience
A remote control of cellular excitability in specific regions deep in tissue would constitute a powerful diagnostic and therapeutic tool. Ultrasound has demonstrated this promise, yet how ultrasound stimulates excitable cells has remained elusive. This study shows that ultrasound acts on tissues as a mechanical stimulus and so opens membrane ion channels. This mechanistic insight informs the design of protocols that maximize the stimulatory effects.

Review article published in Neurosurgical Focus
The understanding of brain function and the capacity to treat neurological and psychiatric disorders rest on the ability
to intervene in neuronal activity in specific brain circuits. Current methods of neuromodulation incur a tradeoff between spatial focus and the level of invasiveness. Transcranial focused ultrasound (FUS) is emerging as a neuromodulation approach that combines noninvasiveness with focus that can be relatively sharp even in regions deep in the brain. This may enable studies of the causal role of specific brain regions in specific behaviors and behavioral disorders. In addition to causal brain mapping, the spatial focus of FUS opens new avenues for treatments of neurological and psychiatric conditions. This review introduces existing and emerging FUS applications in neuromodulation, discusses the mechanisms of FUS effects on cellular excitability, considers the effects of specific stimulation parameters, and lays out the directions for future work.
