The routing of signals through this distributed network is flexible, changing from moment-to-moment to meet task demands. To determine how flexible cortical communication could be instantiated, we recorded spiking activity of neuronal populations across several stages of the macaque cortical visual stream.\u0026nbsp; Using dimensionality reduction methods, we find that inter-areal interactions occur through a communication subspace: downstream fluctuations are related to a small subset of source population activity patterns. Subspaces for feedforward and feedback interactions appear distinct. We propose that the communication subspace may be a general, population-level mechanism by which activity can be selectively and flexibly routed across brain areas.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022Corticocortical Communication\u0022 - Adam Kohn, Ph.D. - Albert Einstein College of Medicine"}],"uid":"27349","created_gmt":"2020-01-02 15:41:20","changed_gmt":"2020-01-02 15:41:20","author":"Floyd Wood","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-02-10T11:15:00-05:00","event_time_end":"2020-02-10T12:15:00-05:00","event_time_end_last":"2020-02-10T12:15:00-05:00","gmt_time_start":"2020-02-10 16:15:00","gmt_time_end":"2020-02-10 17:15:00","gmt_time_end_last":"2020-02-10 17:15:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.neuro.gatech.edu","title":"GT Neuro"},{"url":"http:\/\/www.einstein.yu.edu\/faculty\/10522\/adam-kohn\/","title":"Kohn profile"}],"groups":[{"id":"1292","name":"Parker H.
