DESCRIPTION:Dr Wynn Legon\, Virginia Tech Carilion Research Institute\, V
 A\, USA\nCurrent non-invasive neuromodulation methods such as transcranial
  magnetic stimulation (TMS) and transcranial direct current stimulation (t
 DCS) have proven efficacious for inducing transient changes in  human cor
 tical activity and behavior. However\, these methods suffer from low spati
 al resolution and  typically produce electric fields in the cortex of sev
 eral centimeters spanning multiple gyri. As such\,  these methods stimula
 te the intended area but also surrounding brain regions. In addition\, the
 se  methods also suffer from a depth/focality trade-off and cannot stimul
 ate brain regions deep to the cortical surface. Transcranial focused ultra
 sound (tFUS) confers a superior spatial resolution on a  millimeter scale
  and can also be targeted to areas of the brain deep to the cortical surfa
 ce for potential  non-surgical stimulation of sub-cortical structures. Wi
 th continued research\, it is anticipated that tFUS  can be widely implem
 ented for advancing human brain mapping efforts as well as be translated t
 o  clinical populations for effective non-invasive therapies.\nBio: Dr. L
 egon is a post-doctoral fellow at the Virginia Tech Carilion Research Inst
 itute (VTCRI). He received his Ph.D. from the University of Waterloo (Wate
 rloo\, CAN) in Cognitive and Behavioural Neuroscience before conducting po
 st-doctoral fellowships at  the Centre for Stroke Recovery at Sunnybrook 
 Hospital in Toronto CAN examining neuromodulatory strategies for stroke re
 habilitation and later at the VTCRI exploring the use of focused ultrasoun
 d for non-invasive neuromodulation in humans. The latter work has recently
  been published in Nature Neuroscience and shows for the first time that f
 ocused ultrasound can be targeted through human skull to modulate specific
  cortical circuits. Dr. Legon’s current research aims to advance the use
  of focused ultrasound as a non-invasive neuromodulatory platform for use 
 with functional magnetic resonance imaging (fMRI)\, and to progress ultras
 ound as a feasible alternative to existing neuromodulatory technologies fo
 r both experimental and clinical use.
