Neural coding in high dimensional, nonlinear systems workshop in Paris
by Trang-Anh Nghiem 19 Feb '20

19 Feb '20

Dear Colleagues, We are delighted to announce that our workshop on *neural coding in high dimensional, nonlinear systems* will be held on *March 24th-25 2020*. The event is organised by the European Institute for Theoretical Neuroscience (EITN) and will take place at the Institute for Advanced Study (IAS) on the Île Saint-Louis in central Paris. *Conference abstract* In this workshop we address mechanisms by which brains encode information. We will discuss how neurons - leaky, stochastic channels - interact nonlinearly to entrain synchrony and resonance phenomena thereby reducing dimensionality in dynamics of the cell assemblies coding particular representations. From unconscious to conscious brain states, spontaneous neural signals increase in dimensionality. Since neural codes likely lie on low dimensional manifolds, we explore collapses in dimensionality within encoding networks as mechanisms supporting neural information specifically in conscious states. We aim to bring together researchers in neuroscience, mathematics, physics, and computer science to explore substrates promoting self-organization of neural dynamics, toward a robust understanding of neural codes important for reverse engineering next generation biomimetic computing architectures. *Confirmed speakers*- Mallory Carlu (Centre National de la Recherche Scientifique) - Damien Depannemaecker (Centre National de la Recherche Scientifique) - Alain Destexhe (Centre National de la Recherche Scientifique) - Leon Glass (McGill University) - Jennifer Goldman (Centre National de la Recherche Scientifique) - Julie Grollier (Centre National de la Recherche Scientifique/Thales) - Hermann Haken (Universität Stuttgart) - Vincent Hakim (Ecole Normale Supérieure de Paris) - Viktor Jirsa (Aix-Marseille University) - Trang-Anh Nghiem (Ecole Normale Supérieure de Paris) - Maris Ozols (University of Amsterdam) - Wolf Singer (Ernst Strüngmann Institute, Max Planck Society) - David Ruelle (Paris-Saclay University) - Núria Tort-Colet (Centre National de la Recherche Scientifique) - Sacha van Albada (Forschungszentrum Jülich) *Attendance is free but registration is mandatory due to a limited number of seats.

[meetings] [LM2020] Living Machines 2020 - Second call for papers
by Vicky Vouloutsi 18 Feb '20

18 Feb '20

Dear colleagues, Please find below the second call for papers, satellite events, and sponsors for the 9th International Conference on Biomimetic and Biohybrid Systems of Living Machines, 28th-31st of July 2020. Apologies for cross-posting but please share this announcement with your colleagues. Looking forward to seeing you in Freiburg, Germany! -------------------------------------------------------------------------------------------------------------------------- *Second Call for Papers, Satellite Events and Sponsors* *Living Machines. The 9th International Conference on Biomimetic and Biohybrid Systems* * 28 – 31 July 2020* To be hosted at the Botanical Garden of Freiburg and the Cluster of Excellence livMatS at the University of Freiburg, Germany Accepted papers will be published in *Springer Lecturer Notes in Artificial Intelligence* *Submission deadline: March 23, 2020* http://livingmachinesconference.eu/2020 -------------------------------------------------------------------------------------------------------------------------- *ABOUT LIVING MACHINES 2020* The development of future real-world technologies will depend strongly on our understanding and harnessing of the principles underlying living systems and the flow of communication signals between living and artificial systems. *Biomimetics* is the development of novel technologies through the distillation of principles from the study of biological systems. The investigation of biomimetic systems can serve two complementary goals. First, a suitably designed and configured biomimetic artefact can be used to test theories about the natural system of interest. Second, biomimetic technologies can provide useful, elegant and efficient solutions to unsolved challenges in science and engineering. *Biohybrid* systems are formed by combining at least one biological component—an existing living system—and at least one artificial, newly-engineered component. By passing information in one or both directions, such a system forms a new hybrid bio-artificial entity. The theme of the conference also encompasses biomimetic methods for manufacture, repair, and recycling inspired by natural processes such as reproduction, digestion, morphogenesis, and metamorphosis. The following are some examples of “Living Machines” as featured at past conferences: * Biomimetic robots and their component technologies (sensors, actuators, processors) that can intelligently interact with their environments. * Biomimetic computers—neuromimetic emulations of the physiological basis for intelligent behavior. * Active biomimetic materials and structures that self-organize and self-repair or show other bio-inspired functions. * Nature-inspired designs and manufacturing processes. * Biohybrid brain-machine interfaces and neural implants. * Artificial organs and body-parts including sensory organ-chip hybrids and intelligent prostheses. * Organism-level biohybrids such as robot-animal or robot-human systems. *ACTIVITIES* The main conference will take the form of a *three-day single-track oral* and *poster presentation program*, *28th July to 31st July 2020*, and will be hosted at the Botanical Garden of Freiburg by the University of Freiburg, Germany, and the Cluster of Excellence “Living, Adaptive and Energy-autonomous Materials Systems (livMatS)” (www.livmats.uni-freiburg.de<http://www.livmats.uni-freiburg.de/>). The conference program will include *five plenary lectures* from leading international researchers in biomimetic and biohybrid systems, and the demonstrations of state-of-the-art living machine technologies. The full conference will be preceded by up to two days of *Satellite Events* hosted at the University of Freiburg. *SUBMITTING TO LIVING MACHINES 2020* We invite both *full papers* and *extended abstracts* in areas related to the conference themes. All contributions will be refereed and accepted papers will appear in the Living Machines Proceedings, published in the *Springer-Verlag Lecture Notes in Artificial Intelligence*. Full papers (minimum 8 pages, up to 12 pages) are invited from researchers at any stage in their career and should present significant findings and advances in biomimetic or biohybrid research. More preliminary work is better suited for short paper submission (maximum 4 pages, with a maximum of ten references and no more than three self-citations). Full papers will be accepted for either oral presentation (single track) or poster presentation with a short podium preview. Extended abstracts will be accepted for poster presentations only. Authors of the best full papers will be invited to submitted extended versions of their paper for publication in a special issue of the Taylor & Francis journal *Connection Science*. *SATELLITE EVENTS* Active researchers in biomimetic and biohybrid systems are invited to propose topics for full or half-day *tutorials*, *symposia* or *workshops* on related themes to be held on 28. July at the Institute for Biology II/III of the University of Freiburg (http://www.bio.uni-freiburg.de/index-en?set_language=en) Attendance at satellite events will attract a small fee intended to cover the costs of the meeting. There is flexibility about the content, organization, and budgeting for these events. Please contact us if you are interested in organizing a satellite event! *EXPECTED DEADLINES* March 23, 2020: Paper submission deadline May 15, 2020: Notification of acceptance May 25, 2020: Camera-ready copy July 28, 29-31, 2020 Workshops and Conference *SPONSORSHIP* Organizations wishing to sponsor the conference in any way and gain the corresponding benefits by promoting themselves and their products through conference publications, conference events, and conference publicity are encouraged to contact the organizers to discuss the terms of sponsorship and necessary arrangements. We also offer a number of attractive options for potential sponsors. *VENUE* Consistent with the Living Machines’ tradition of choosing historical venues at the crossroads between life and human sciences, this year the conference will take place at the Botanical Garden of Freiburg. Freiburg is considered the gateway to the Black Forest and thanks to its geographical location is blessed with mild weather all year round. The city is over 900 years old and known to be the sunniest city(1,740 hours of sunshine/year) in Germany. Freiburg has a beautiful historical inner city and is home to one of the oldest universities and Botanical Gardens in Germany. The Botanical Garden Freiburg will be celebrating its 400 year anniversary in 2020 and is located in the district Herdern near the Botanical Institute of the University of Freiburg. The Botanical Garden invites visitors to enjoy its wonderful greenery and learn about both plants from all around the world and plant-based biomimetics with its biomimetic educational trail. The trail highlights biomimetic inventions based on plants while providing fascinating insights into underlying biological principles. *CONFERENCE ORGANIZING COMMITTEE* *Thomas Speck* University of Freiburg, Germany (Local Chair) *Paul Verschure* IBEC, BIST, ICREA, CSN Foundation (Co-Chair) *Tony Prescott* University of Sheffield, CSN Foundation (Steering Committee) *Anna Mura* IBEC, BIST Barcelona, CSN Foundation (General Organization) *PROGRAM CHAIR* *Vicky Vouloutsi* IBEC, BIST, Barcelona *COMMUNICATION* *Sonja Seidel* University of Freiburg, Germany *Yulia Sandamirskaya* INI, Zurich Univ. and ETH *WORKSHOPS CHAIR* *Falk Esser* University of Freiburg, Germany *LOCAL ORGANIZERS COMMITTEE* *Thomas Speck* University of Freiburg, Germany *Falk Esser* University of Freiburg, Germany *Sonja Seidel* University of Freiburg, Germany Aquest correu electrònic conté informació confidencial emparada pel secret professional.

by Dimitris Pinotsis 18 Feb '20

18 Feb '20

PhDStudentship – Modelling cortico-subcortical oscillatory connectivity. Applicationsare invited for a 3-year funded PhD studentship in the Wellcome Centre forHuman Neuroimaging (https://www.fil.ion.ucl.ac.uk/) under the supervision ofDr. Vladimir Litvak and Dr. Simon Farmer and in collaboration with theComputational Neuroscience Group (CNS, https://www.upf.edu/web/cns) led byProf. Gustavo Deco, at the Center for Brain and Cognition(https://www.upf.edu/web/cbc), Pompeu Fabra University (Barcelona, Spain). The position is part of the EU-fundedInnovative Training Network euSNN (“European School of Network Neuroscience”)and available, with full-time employment, for a duration of 3 years withimmediate start. TheeuSNN Innovative Training Network integrates 16 leading European groups innetwork neuroscience and 7 companies to train students who want to pursue asuccessful career in the field of network neuroscience. The euSNN trainingprogramme offers a unique combination of experimental, analysis and modellingapproaches. Exploiting intense collaborations between experimental, theoreticaland clinical groups, euSNN links basic research on large-scale brain dynamicswith new pathophysiological approaches and clinical applications. The euSNNnetwork is coordinated by Prof. Dr. Andreas K. Engel. Further information onthe euSNN network can be found at http://eusnn.eu. Project details Deep Brain Stimulation(DBS) is an effective treatment method for a range of neurological andpsychiatric conditions. It involves placing electrodes deep in a patient’sbrain, usually in precisely targeted subcortical nuclei. DBS surgery affords aunique opportunity to study the neural activity of these nuclei via recordingof local electrical signals known as local field potentials (LFP). Our grouppioneered simultaneous recording of subcortical LFP with non-invasive wholebrain imaging using magnetoencephalography (MEG). This makes it possible to mapout cortico-subcortical oscillatory coherent networks which have characteristicfrequencies and cortical topographies for each subcortical target. Over theyears we collected data from several different subcortical nuclei andcharacterised their oscillatory networks. The aim of the proposed project is toestablish a modelling framework which could accommodate these findings and makequantitative predictions for future experiments. This will require extendingexisting models of cortical dynamics and integrating information fromadditional imaging modalities such as functional MRI and Diffusion TensorModelling (DTI). The euSNN training networkoffers exciting and unique opportunities for the student to pursue this projectincluding interactions with top experts in neuroimaging brain modelling andexposure to several different modelling frameworks and approaches that thestudent will have to master and integrate to achieve the project’s goals. Theremight also be opportunities towards the end of the project to test some of thepredictions experimentally. In addition, the student will have a chance to workon secondments with commercial companies on topics relevant to the project. Funding notes The starting date can beany date between being offered the position and 1st October 2020 andthe contract is for 36 months.

Grandmother cells a failed concept? Or is Barlow right that grandmother cells exist and “can now be recorded from and studied reliably?"
by Asim Roy 16 Feb '20

16 Feb '20

Ann-Sophie Barwich recently published an article in Frontiers in Neuroscience titled “The Value of Failure in Science: The Story of Grandmother Cells in Neuroscience” (https://www.frontiersin.org/articles/10.3389/fnins.2019.01121/full) where she argues for the need for failure analysis in science and, in the context of neuroscience, analyzed the grandmother cell concept as a failed one. Although I was one of the reviewers who endorsed the article for publication (publication of alternative viewpoints is essential in science), I felt that Barwich’s arguments against grandmother cells were deeply flawed. I point out these flaws in a Commentary in Frontiers in Neuroscience: “Commentary: The Value of Failure in Science: The Story of Grandmother Cells in Neuroscience:” https://www.frontiersin.org/articles/10.3389/fnins.2020.00059/full I think Reddy and Thorpe’s 2014 article clears the confusion about concept cells. With Reddy and Thorpe’s characterization of concept cells, one would find no difference between concept cells and grandmother cells. And that’s essentially what I have done in the Commentary – show that concept cells and grandmother cells have identical properties. I also point out in the Commentary that it’s a false claim by Barwich (and in other prior articles that Barwich references) that concept cells can be part of a sparse population coding scheme. Given that concept cells have “meaning” on a stand-alone basis, they can’t be part of any population coding scheme. And it’s also a false claim in Barwich that grandmother cells do not use associative learning, because grandmother cells have always been characterized as “multimodal” going all the way back to Gross (2002). In addition, the neurophysiological evidence on multisensory neurons clearly point to a single-cell based abstract cognitive system in the brain, as claimed by Roy (2017). Overall, concept cell findings confirm the prediction of Barlow (2009)<https://www.frontiersin.org/articles/10.3389/fnins.2020.00059/full#B1> that grandmother cells exist and “can now be recorded from and studied reliably.” YOU CAN EMAIL ME IF YOU WANT TO JOIN A DISCUSSION GROUP ON THIS TOPIC.
