One of many unique features of the mammalian cortico-thalamic network is its hierarchical organization. I will discuss functional implications of the hierarchical structure of mammalian cortical network in the framework of predictive coding. Specifically, I will focus on a hierarchical predictive coding model of visual cortex to understand how robust encoding of noisy visual stimuli emerges, and further discuss distinct computations carried out by layer-specific feedforward and feedback connections in the cortical hierarchy. In the second part of the talk, I will discuss how various visual stimuli shape the complexity of functional networks of neural activity by analyzing their network properties.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Biological Sciences Seminar by Hannah Choi, Ph.D."}],"uid":"27964","created_gmt":"2021-10-25 00:32:33","changed_gmt":"2021-10-25 00:33:17","author":"Jasmine Martin","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-11-18T11:00:00-05:00","event_time_end":"2021-11-18T12:00:00-05:00","event_time_end_last":"2021-11-18T12:00:00-05:00","gmt_time_start":"2021-11-18 16:00:00","gmt_time_end":"2021-11-18 17:00:00","gmt_time_end_last":"2021-11-18 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1275","name":"School of Biological Sciences"}],"categories":[],"keywords":[{"id":"189151","name":"Hannah Choi"},{"id":"189152","name":"Dr. Hannah Choi"},{"id":"170037","name":"Joe Lachance"},{"id":"166881","name":"Joseph Lachance"},{"id":"166892","name":"School of Biological Sciences Seminar"},{"id":"168854","name":"School of Mathematics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
