28 Apr '14

Post-doc (or PhD student) in Computational and Cognitive Neuroscience - What is the role of the cortical layers? A post-doc (or PhD student) position is available to study computational models about the roles of the different layers of the cerebral cortex in the Vision & Cognition group (head Pieter Roelfsema) at the Netherlands Institute for Neuroscience in Amsterdam. What roles do the different cortical layers play in visual processing? This project, funded by the Human Brain Project, aims to build computational models for the unique contributions of the different cortical layers to perceptual processing. We recently discovered that the cortical layers have different roles in visual perception (Self et al., Curr. Biol, 2013). We now wish to understand this subdivision of labor by making models of the layers and the interactions between them that take place in the visual cortex during perception. The candidate will have close interactions with researchers addressing laminar processing with high-field fMRI. The successful applicant will have a solid computational background and an interest in cognitive neuroscience, preferably affinity with neuroimaging, and good programming skills. Appointment: The position involves a temporary appointment for 2-4 years. To apply, please send application letter, CV and two letters of recommendation to: Tini Eikelboom The Netherlands Institute for Neuroscience Meibergdreef 47 1105 BA Amsterdam, The Netherlands Telephone: +31-20-5664587 E-mail: t.eikelboom(a)nin.knaw.nl<mailto:t.eikelboom@nin.knaw.nl>

International Workshop on The Versatile Action of Noise, June 22-27, 2014 in Bremen
by Alberto Bernacchia 24 Apr '14

24 Apr '14

Dear Colleagues, we are organizing an international workshop on *The Versatile Action of Noise: Applications from Genetic to Neural Circuits* at Jacobs University Bremen, Germany from June 22-27, 2014. http://noise-workshop.user.jacobs-university.de/<https://exchange.jacobs-university.de/owa/redir.aspx?C=gZfK3TmIBkiF8b5kI43d…> Stochastic mechanisms, often summarized under “noise”, are ubiquitous in artificial and biological networks. In applications to genetic circuits the goal is to trace back the various manifestations of noise to a few sources on underlying levels like the stochastic fluctuations in biochemical reactions, to follow the propagation and modification of noise towards the cellular level and to pursue the interaction of different sources of noise with respect to their mutual repression or amplification. In applications to neural systems the focus is on microscopic noise, e.g. the thermal fluctuations on channel dynamics, the effect of synaptic noise on neuronal firing, but also on large-scale collective fluctuations of brain areas, information loss, effects of large-scale noise on attention and decision-making, as well as on bridges between the different levels. A comparison between both types of applications should reveal parallels in how natural systems transform or utilize noise. It is the tools of theoretical physics that provide a deeper understanding of its role, in particular when it acts counterintuitive. Advanced methods from statistical physics and nonlinear dynamics allow for predicting the action of noise on excitable media like neural systems, extinction events in various populations and noise-induced rare events. *We invite applications from graduate students, PhD students and postdocs with a background in theoretical physics, applied mathematics with an interest in biological applications and neuroscience. Applicants from the experimental side should be interested in the mathematical modeling and analysis of experimental data.* The fee is *150 Euro* *for early registration until April 30* and 250 Euro afterwards, including accommodation in the guesthouse on campus and all meals, for the period of the workshop. The workshop is generously supported by the WE-Heraeus foundation. For registration please visit our website.

[RSS2014] CfP: First Workshop on Affordances: Affordances in "Vision for Cognitive Robotics" (in conjunction with RSS 2014)
by Karthik Mahesh Varadarajan 23 Apr '14

23 Apr '14

====================================================================== *Call for Papers- First Workshop on Affordances: Affordances in Vision for Cognitive Robotics* (in conjunction with RSS 2014), July 13, 2014, Berkeley, USA http://affordances.info/workshops/RSS.html ====================================================================== Based on the Gibsonian principle of defining objects by their function, "affordances" have been studied extensively by psychologists and visual perception researchers, resulting in the creation of numerous cognitive models. These models are being increasingly revisited and adapted by computer vision and robotics researchers to build cognitive models of visual perception and behavioral algorithms in recent years. This workshop attempts to explore this nascent, yet rapidly emerging field of affordance based cognitive robotics while integrating the efforts and language of affordance communities not just in computer vision and robotics, but also psychophysics and neurobiology by creating an open affordance research forum, feature framework and ontology called AfNet (theaffordances.net). In particular, the workshop will focus on emerging trends in affordances and other human-centered function/action features that can be used to build computer vision and robotic applications. The workshop also features contributions from researchers involved in traditional theories to affordances, especially from the point of view of psychophysics and neuro-biology. Avenues to aiding research in these fields using techniques from computer vision and cognitive robotics will also be explored. Primary topics addressed by the workshop include the following among others - Affordances in visual perception models - Affordances as visual primitives, common coding features and symbolic cognitive systems - Affordances for object recognition, search, attention modulation, functional scene understanding/ classification - Object functionality analysis - Affordances from appearance and touch based cues - Haptic adjectives - Functional-visual categories for transfer learning - Actions and functions in object perception - Human-object interactions and modeling - Motion-capture data analysis for object categorization - Affordances in human and robot grasping - Robot behavior for affordance learning - Execution of affordances on robots - Affordances to address cognitive and domestic robot applications - Affordance ontologies - Psychophysics of affordances - Neurobiological and cognitive models for affordances The workshop also seeks to address key challenges in robotics with regard to functional form descriptions. While affordances describe the function that each object or entity affords, these in turn define the manipulation schema and interaction modes that robots need to use to work with objects. These functional features, ascertained through vision, haptics and other sensory information also help in categorizing objects, task planning, grasp planning, scene understanding and a number of other robotic tasks. Understanding various challenges in the field and building a common language and framework for communication across varied communities in are the key goals of the proposed workshop. Through the course of the workshop, we also envisage the establishment of a working group for AfNet. An initial version is available online at www.theaffordances.net. We hope the workshop will serve to foster greater collaboration between the affordance communities in various fields. *Paper Submissions* Paper contributions to the workshop are solicited in four different formats - *Conceptual papers* (1 page): Authors are invited to submit original ideas on approaches to address specific problems in the targeted areas of the workshop. While a clear presentation of the proposed approach and the expected results are essential, specifics of implementation and evaluations are outside the scope of this format. This format is intended at exchange and evaluation of ideas prior to implementation/ experimental work as well as to open up collaboration avenues. - *Design papers* (3 pages): Authors submitting design papers are required to address key issues regarding the problem considered with detailed algorithms and preliminary or proof-of-concept results. Detailed evaluations and analyses are outside the scope of this format. This format is intended at addressing late-breaking and work in progress results as well as fostering collaboration between research and engineering groups. - *Experimental papers* (3 pages): Experimental papers are required to present results of experiments and evaluation of previously published algorithms or design frameworks. Details of implementation and exhaustive test case analyses are key to this format. These papers are geared at benchmarking and standardizing previously known approaches. - *Full papers* (5 pages): Full papers must be self-inclusive contributions with a detailed treatment of the problem statement, related work, design methodology, algorithm, test-bed, evaluation, comparative analysis, results and future scope of work. Submission of original and unpublished work is highly encouraged. Since the goal of this workshop is to bring together the various affordance communities, extended versions/ summary reports of recent research published elsewhere, as adapted to the goals of the workshop, will also be accepted. These papers are required to clearly state the relevance to the workshop and the necessary adaptation. The program will be composed of oral as well as Pecha-Kucha style presentations. Each contribution will be reviewed by three reviewers through a single-blind review process. The paper formatting should follow the RSS formatting guidelines (Templates: Word<http://www.roboticsconference.org/paper-template-word.zip> andLaTeX <http://www.roboticsconference.org/paper-template-latex.tar.gz>). All contributions are to be submitted via Microsoft Conference Management Tool <https://cmt.research.microsoft.com/A2014/Default.aspx> in PDF format. Appendices and supplementary text can be submitted as a second PDF, while other materials such as videos (though, preferably as links on vimeo or youtube) as a zipped file. All papers are expected to be self-inclusive and supplementary materials are not guaranteed to be reviewed. Please adhere to the following strict deadlines. In addition to direct acceptance, early submissions may be conditionally accepted, in which case submission of a revised version of the paper based on reviewer comments, prior to the late submission deadline is necessary. The final decision on acceptance of such conditionally accepted papers will be announced along with the decisions for the late submissions. *Important Dates* - Initial submissions (Early): 23:59:59 PDT May 5, 2014 - Notification of acceptance (Early submissions): May 15, 2014 - Initial submissions (Late): 23:59:59 PDT May 27, 2014 - Notification of acceptance (Late submissions): June 5, 2014 - Submission of publication-ready version: June 10, 2014 - Workshop date: July 13, 2014 *Organizers* Karthik Mahesh Varadarajan <http://www.karthikmahesh.com/> (varadarajan(at) acin.tuwien.ac.at), TU Wien Markus Vincze <http://www.acin.tuwien.ac.at/index.php?id=231&L=1> (vincze(at)tuwien.ac.at), TU Wien Trevor Darrell <http://www.eecs.berkeley.edu/~trevor/> (trevor(at) eecs.berkeley.edu), UC.

new MATLAB toolbox for Granger causality analysis
by Anil Seth 23 Apr '14

23 Apr '14

Dear all, Lionel Barnett and I are pleased to announce the availability of our wholly new MATLAB toolbox for implementing Granger causality analysis. This new free software is a wholesale revision of my previous ‘GCCA’ toolbox which has been available since 2010 (http://www.ncbi.nlm.nih.gov/pubmed/19961876), and which has enjoyed a wide uptake within the neuroscience community and beyond. Granger causality is a powerful analysis method which can be used to detect directed functional connectivity in stationary time-series data, of the sort often (but not always) found in neuroscience datasets. The new ‘multivariate Granger causality’ ‘MVGC’ toolbox offers a range of enhancements. It easily handles conditional spectral analyses. It requires only estimation of the ‘full’ regression model, avoiding biases inherent in estimation of both full and reduced models. It is accompanied by a fully functional help system integrated into the online MATLAB documentation. And much else besides. The toolbox can be downloaded here: http://www.sussex.ac.uk/sackler/mvgc/ A paper describing the toolbox and the basic concepts and maths underlying Granger causality has been recently published in Journal of Neuroscience Methods: http://www.sciencedirect.com/science/article/pii/S0165027013003701 … which is the appropriate citation for any published work utilizing the software.
