The main focus of my laboratory at the NIH is to study how large-scale brain dynamics relate to human cognition \u2013 in particular, perceptual awareness \u2013 while taking into account perspectives gained from studying spontaneous brain activity and nonlinear brain dynamics. For instance, our recent findings using fMRI and ECoG in humans suggest that the effect of a sensory stimulus or task demand is not to evoke a stereotypical response that adds linearly onto the constantly changing ongoing activity. By contrast, in line with nonlinear dynamical systems view, incoming sensory stimuli strongly interact with ongoing cortical dynamics to actively shape the evolving cortical activity trajectory. In this talk, I will discuss our recent studies using multimodal imaging (fMRI\/EEG\/MEG) and brain stimulation in humans, combined with computational approaches, to study the neural bases of perceptual awareness and movement intention. These studies illustrate the importance of understanding the roles of spontaneous activity, nonlinear dynamics, and top-down predictions in shaping perception and action.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe Neural Engineering Center hosts seminars, workshops, retreats, and seed grants to promote novel, collaborative research of the science and technology of neural stimulation.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"\u201cUnraveling Large-scale Brain Dynamics Underlying Perceptual Awareness\u201d - Biyu Jade He, Ph.D. - National Institute of Health"}],"uid":"27513","created_gmt":"2015-09-14 09:58:24","changed_gmt":"2017-04-13 21:18:20","author":"Walter Rich","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-09-22T16:30:00-04:00","event_time_end":"2015-09-22T17:30:00-04:00","event_time_end_last":"2015-09-22T17:30:00-04:00","gmt_time_start":"2015-09-22 20:30:00","gmt_time_end":"2015-09-22 21:30:00","gmt_time_end_last":"2015-09-22 21:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"https:\/\/neuroscience.nih.gov\/ninds\/he\/lab_members.html","title":"He lab website"},{"url":"http:\/\/neuralengineering.gatech.edu\/","title":"Neural Engineering Center website"}],"groups":[{"id":"1254","name":"Wallace H.
