This surface turns out to have a negative curvature, corresponding to a hyperbolic metric. Although this map was derived purely from the statistics of co-occurrence between mono-molecular odorants in the natural environment it revealed topography in the organization of human perception of smell. I will conclude with arguments for why hyperbolic metric should be generally applicable elsewhere in the nervous system.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022Hyperbolic Geometry of the Olfactory Space\u0022 - Tatyana Sharpee, Ph.D. - Salk Institute"}],"uid":"27349","created_gmt":"2019-10-17 13:08:26","changed_gmt":"2019-10-17 13:08:26","author":"Floyd Wood","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-11-04T11:15:00-05:00","event_time_end":"2019-11-04T12:15:00-05:00","event_time_end_last":"2019-11-04T12:15:00-05:00","gmt_time_start":"2019-11-04 16:15:00","gmt_time_end":"2019-11-04 17:15:00","gmt_time_end_last":"2019-11-04 17:15:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/neuro.gatech.edu\/","title":"GT Neuro"},{"url":"https:\/\/www.salk.edu\/scientist\/tatyana-sharpee\/","title":"Sharpee lab"}],"groups":[{"id":"1292","name":"Parker H.
