Image-Guided Transcranial Focused Ultrasound Stimulates Human Primary Somatosensory Cortex
Wonhye Lee,Hyung-Min Kim,Yu Jin Jung,In-Uk Song,Yong-An Chung,Seung-Schik Yoo,Seung-Schik Yoo +6 more
TL;DR: The transient and localized stimulation of the brain using image-guided transcranial FUS may serve as a novel tool for the non-invasive assessment and modification of region-specific brain function.
Journal ArticleDOI
Transcranial focused ultrasound stimulation of human primary visual cortex.
Wonhye Lee,Hyun-Chul Kim,Yu Jin Jung,Yong-An Chung,In Uk Song,Jong-Hwan Lee,Seung-Schik Yoo,Seung-Schik Yoo +7 more
TL;DR: FUS sonication of the primary visual cortex in humans is reported, resulting in elicited activation not only from the sonicated brain area, but also from the network of regions involved in visual and higher-order cognitive processes.
Journal ArticleDOI
Focused ultrasound-mediated suppression of chemically-induced acute epileptic EEG activity
Byoung-Kyong Min,Alexander Bystritsky,Kwang Ik Jung,Krisztina Fischer,Yongzhi Zhang,Lee-So Maeng,Sang In Park,Yong-An Chung,Ferenc A. Jolesz,Seung-Schik Yoo +9 more
TL;DR: Low-intensity, pulsed FUS sonication suppressed the number of epileptic signal bursts using acute epilepsy model in animal, which was induced by the intraperitonial injection of pentylenetetrazol.
Journal ArticleDOI
Simultaneous acoustic stimulation of human primary and secondary somatosensory cortices using transcranial focused ultrasound.
TL;DR: The use of multiple FUS transducers allowed for simultaneous stimulation of the SI/SII in the same hemisphere and elicited various tactile sensations in the absence of any external sensory stimuli.
Journal ArticleDOI
Alterations in cerebral perfusion in posttraumatic stress disorder patients without re-exposure to accident-related stimuli.
Yong-An Chung,Sung Hoon Kim,Soo Kyo Chung,Jeong-Ho Chae,Dong Won Yang,Hyung Sun Sohn,Jaeseung Jeong,Jaeseung Jeong +7 more
TL;DR: This result indicates that PTSD patients have alterations in cerebral perfusion of limbic regions and the frontal and temporal cortex without re-exposure to accident-related stimuli, and supports the hypothesis of the involvement of limbsic regions, which might be associated with the regulation of emotion and memory, in the pathophysiology of PTSD.
