applications, including brain tissue ablation, 19 , 32 , 36 , 48 blood-brain barrier opening for therapeutic agent delivery, 24 , 57 thrombolysis, 3 , 7 and potentiation of the anticancer immune response. 53 , 58 Currently, available clinical TcMRgFUS devices operate at 650 kHz. 12 , 36 , 38 Lower-frequency (e.g., 220-kHz 1 , 11 , 43 ) devices exist but at the present time are reserved for research. There are several advantages of using a low-frequency TcMRgFUS device. First, the larger ratio of wavelength to path length in the skull bone at 220 kHz results in reduced

postradiosurgery complications were followed very closely and had frequent imaging and clinical evaluations and thus might be overrepresented in this cohort. The patients were not all seen at exactly regular follow-up intervals, which made time-to-event statistical analysis less accurate. Treatment was carried out over a long time period and was subject to change in the radiosurgical device, imaging, and software used. Moreover, radiosurgical technology and treatment algorithms have been refined over the study period, and this could have contributed to a bias. Despite these

that the acute and chronic effects of DBS on neural networks can be examined. In this study, idiopathic epilepsy was characterized for the first time in a nonhuman primate (NHP) implanted with the PC+S device, and the effect of DBS on local field potential (LFP) activity was examined. Methods Clinical DBS electrodes were implanted in the hippocampus bilaterally in an NHP with idiopathic epilepsy. Baseline LFP recordings were collected for seizure characterization using the PC+S device. The effects of variable DBS stimulation paradigms delivered acutely under
