2 Post-doc positions on the relation of information and causation (Prof. Giulio Tononi)
by Larissa Albantakis 17 Dec '14

17 Dec '14

Up to 2 postdoctoral positions are available at the center for sleep and consciousness science in the laboratory of Dr. Giulio Tononi (University of Wisconsin, Madison), to study the relation of information and causation within the framework of the integrated information theory of consciousness (Balduzzi & Tononi, 2008; Tononi, 2012). Immediate funding is available for a range of projects related to foundational questions regarding the ontological status of information, and its relation to causation, emergence, adaptation, evolution, and consciousness (see detailed scope of work below). Successful candidates will work at the center for sleep and consciousness science, dedicated to a broad range of research problems focused on two neurobiological problems -- the mechanisms and functions of sleep and the neural substrates of consciousness. Candidates are expected to have strong training in an analytically rigorous discipline such as theoretical biology/neuroscience, physics, mathematics, computer science, or engineering. For at least one of the positions, we explicitely encourage mathematicians to apply. Experience in information theory, complex systems, and an interest in the philosophy of information/causation are a plus. Programming experience is required (knowledge of MATLAB and/or C++ is of advantage). Appointments are renewable from year to year for up to 3 years, starting as soon as possible or until the positions are filled. Post-doc salaries correspond to the National Institutes of Health National Research Service Award (NRSA) stipend schedule for postdoc trainees, based on number of years of postdoctoral experience. Candidates should send a CV, brief statement of previous research and future research interests, and email addresses and phone numbers of three references to: Giulio Tononi, gtononi(a)wisc.edu. Balduzzi D, Tononi G (2008) Integrated information in discrete dynamical systems: motivation and theoretical framework. /PLoS Comput Biol/ 4:e1000091. Hoel, E. P., Albantakis, L., & Tononi, G. (2013). Quantifying causal emergence shows that macro can beat micro. /PNAS/, /110/(49), 19790--19795. Tononi G (2012) Integrated Information Theory of Consciousness: An Updated Account. /Arch Ital Biol/ 150:56--90. The scope of work will range from: -theoretical development and computational implementation of the notion of intrinsic causal information -causal analysis, including the systematic use of perturbations, counterfactuals, and irreducibility -analysis of complex systems in terms their causal/informational structure -meaning (understanding and control) from the intrinsic perspective of the system -actual causation (causal explanation) -examining similarities and differences between existing notions of information and causation (Shannon information, algorithmic information,...) -defining emergence in terms of the spatio-temporal grain size at which a system of elements achieves a maximum of causal power -evolutionary/adaptive aspects of information/causation including simulations based on small adaptive neural networks (animats), which evolve and adapt to an environment that requires sensitivity to context for survival

Open Source Brain workshop 2014: Building and sharing models of the cortex
by solinas 31 Mar '14

31 Mar '14

(Apologies for cross postings) Announcing the 2014 Open Source Brain Workshop: Building and sharing models of the cortex. May 14-16th, Alghero, Sardinia. There are an increasing number of cortical cell and network models being developed and made publicly available, from networks of leaky integrate and fire neurons based on cortical connectivity and firing properties, to multicompartmental, conductance based cell models. Many of these are being reused, reimplemented and extended to address new scientific questions by labs around the world. In this meeting, we will look at the range cortico-thalamic models out there which are of widespread interest and work towards getting these into public, open source repositories, in standardised formats such as NeuroML and PyNN. We will investigate the steps needed to ensure these models are well tested, annotated and ready for use as research tools by the attendees and the wider community. There will be presentations from experimentalists who are producing the data to constrain these models, as well as simulator and application developers who will create the infrastructure to build, simulate, analyse and share the models. On the morning of Friday 16th, there will be a symposium on Oscillation and Resonance in CNS Network Loops. The symposium will focus on the reconstruction and analysis of oscillating networks. These methods can be applied at multiple levels of brain modelling providing valuable constraints for single neuron and network models. There will be presentations of modelling studies on how the brain generates oscillations and how external, oscillating electro-magnetic fields influence brain activity. Confirmed speakers Sharon Crook, Arizona State University, USA Markus Diesmann, Research Center Jülich, Germany Dirk Feldmeyer, Aachen University, Germany Alon Korngreen, Bar-Ilan University, Israel Dave Lester, SpiNNaker project, University of Manchester, UK Robert A.

New book - Directed Information Measures in Neuroscience
by Joseph Lizier 31 Mar '14

31 Mar '14

Dear all, We are pleased to announce the publication of the following edited book: "Directed Information Measures in Neuroscience" edited by Michael Wibral, Raul Vicente, Joseph T. Lizier in series "Understanding Complex Systems", Springer, Berlin, 2014. About the book: http://www.springer.com/physics/complexity/book/978-3-642-54473-6 Analysis of information transfer has found rapid adoption in neuroscience, where a highly dynamic transfer of information continuously runs on top of the brain's slowly-changing anatomical connectivity. Measuring such transfer is crucial to understanding how flexible information routing and processing give rise to higher cognitive function. Directed Information Measures in Neuroscience reviews recent developments of concepts and tools for measuring information transfer, their application to neurophysiological recordings and analysis of interactions. Written by the most active researchers in the field the book discusses the state of the art, future prospects and challenges on the way to an efficient assessment of neuronal information transfer. Highlights include the theoretical quantification and practical estimation of information transfer, description of transfer locally in space and time, multivariate directed measures, information decomposition among a set of stimulus/responses variables and the relation between interventional and observational causality. Applications to neural data sets and pointers to open source software highlight the usefulness of these measures in experimental neuroscience. With state-of-the-art mathematical developments, computational techniques and applications to real data sets, this book will be of benefit to all graduate students and researchers interested in detecting and understanding the information transfer between components of complex systems.
