Announcement : Workshop Cortical codes Organized by Sacha van Albada and the EITN  on February 5th and 6th, at the EITN Paris. Programme and registration: https://eitnconf-050218.sciencesconf.org/ The cerebral cortex plays a key role in high-level brain functions including sensory processing, memory, attention, planning, and the internal modeling of the external world. To make sense of the wealth of experimental data available on cortical anatomy and physiology, and the relation of its activity to behavior, theoretical approaches are essential. A variety of tools are used for this purpose: bottom-up modeling starting from biological knowledge, top-down including normative approaches, investigations of the coding properties at the single-neuron and neuronal population levels, analytical work and simulations, and comparisons between healthy and disease conditions. This workshop brings together a cross-section of these theoretical approaches toward unraveling the mechanisms used by the cerebral cortex for achieving its functionality, with the goal of facilitating mutual fertilization between the various approaches. **/The registration is free however mandatory due to a limited number of seats./** Speakers:**/ /** Claudia Clopath, Cold Spring Harbor, USA Sophie Denève, ENS Paris, France Maria Sanchez-Vives, IDIBAPS Barcelona, Spain Yulia Sandamirskaya, University and ETH, Zurich, Switzerland Tatyana Sharpee, Salk Institute, La Jolla, USA (via video conference) Hamutal Slovin, Bar Ilan University, Tel Aviv, Israel Alexa Riehle, AMU, France Angela Yu, University of California San Diego, USA (via video conference) Fleur Zeldenrust, Radboud University, The Netherlands Looking forward to seeing you there ! -- The EITN Team Phone : +33 (0)1 69 82 34 39 http://www.eitn.org follow us on Twitter: @EITN_Paris
