Frontiers Computational Neuroscience call for papers on "Integrating computational and neural findings in visual object perception"
by Peters J (PSYCHOLOGY) 18 Mar '14

18 Mar '14

Frontiers in Computational Neuroscience, special issue on "Integrating computational and neural findings in visual object perception" http://www.frontiersin.org/computational_neuroscience/researchtopics/integr… Abstract submission deadline: Apr 1st 2014 Full paper submission deadline: June 1st 2014 Topic editors: Judith Peters Maastricht University / The Netherlands Institute for Neuroscience, The Netherlands Hans Op De Beeck University of Leuven (KU Leuven), Belgium Rainer Goebel Maastricht University / The Netherlands Institute for Neuroscience, The Netherlands The advent of new imaging techniques such as ultra-high field fMRI and advanced multi-unit recordings provide insights into large-scale neural activation patterns underlying visual object perception with unprecedented detail. In parallel, innovative neuroscientific applications of machine learning and computational methods, including various encoding and decoding methods (Miyawaki et al., 2008; Naselaris et al., 2011), representational similarity analysis (Kriegeskorte et al., 2008; Op de Beeck et al., 2001), and hyperalignment (Haxby et al., 2011) have been developed, offering novel opportunities to tackle longstanding questions concerning the neural correlates of object representations (e.g., DiCarlo et al., 2012; Marr, 1982; Biederman, 1987). Likewise, new techniques to integrate simulated and empirical data (e.g., Braet, Kubilius, Wagemans, & Op de Beeck, in press; Peters et al., 2012, 2010; Goebel & De Weerd 2009) allow direct testing of neural findings against predictions of various computational object perception models, which may facilitate the incremental, cross-fertilized development of both biologically-validated machine vision models as well as computationally interpretable empirical models of neural object perception. The aim of this Research Topic is to provide a forum for state-of-the-art research integrating computational and empirical approaches to study the neural mechanisms underlying visual object perception as it is observed behaviorally in humans as well as other animals, including nonhuman primates and rodents. We welcome contributions addressing computational mechanisms underlying object perception related - but not limited - to key questions such as: * What is the nature of neural object representations (e.g., the degree of invariance, sparseness) and how do these representations change across different processing stages? * How are object features (e.g., Tanaka, 1996) computationally integrated into coherent object representations? * How do object representations in the ventral visual system allow invariant recognition without losing specificity to distinguish between similar exemplars? * How are object representations read-out by higher-order areas (e.g., hippocampus and prefrontal cortex), and how do current task instructions (e.g., between- versus within-category discrimination) or past experiences influence this read-out? * How are object perception mechanisms shaped by experience and development? * How can we optimally compare computer vision models to empirically-derived neural models based on human or animal object perception? Pre-submission inquiries can be sent to Judith Peters ( j.peters(a)maastrichtuniversity.nl<mailto:j.peters@maastrichtuniversity.nl>). All articles become freely available upon publication and benefit from the unique marketing tools developed by Frontiers. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Judith Peters (PhD) Maastricht Brain Imaging Center (M-BIC), Maastricht University Faculty of Psychology and Neuroscience, Maastricht University Neuroimaging and Neuromodeling group, Netherlands Institute for Neuroscience, Amsterdam

Open Frontiers in neuroRobotics Research Topic
by Ajaz Ahmad Bhat 18 Mar '14

18 Mar '14

A new research topic in Frontiers in NeuroRobotics "Motor cognition in animals and animates: Melting Neuroscience with Embodied Robotics" is open for abstracts submission. Emerging trends in motor neuroscience now provide converging evidence for this perspective and substantiate the fact that action 'generation, observation, imagination and understanding' share underlying functional networks in the brain. In this sense, overt actions are just the tip of an iceberg: under the surface is hidden a vast territory of actions without movements (covert actions). Unravelling and unifying the neural/computational basis of such mechanisms is the essence of motor cognition. This Research Topic looks for novel insights that can help "melting" the gap between "how the brains do it" and how we can create "better artifacts i.e. autonomous robotic assistants" that can intelligently and dexterously support us in the worlds that we inhabit and create. Full details are: http://www.frontiersin.org/Neurorobotics/researchtopics/Motor_cognition_in_… Best regards, Ajaz Bhat PhD-Fellow ajaz.bhat(a)iit.it<mailto:ajaz.bhat@iit.it>

cybernetics in the brain
by Danko Nikolic 17 Mar '14

17 Mar '14

Dear members, I would like to bring to your attention a newly available manuscript that dives into the mind-body problem using the approaches of cybernetics. The proposed theory describes the interaction between neurons, plasticity, genetics, and other biological phenomena in terms of feedback loops closed with the environment. This effort has a wonderful result: One can identify a missing component of today's brain theories--a component that is the "missing link" for explaining how mental phenomena emerge from physical events, and which is a result that could not be obtained with the classical "representational" approach. Those who intend to take a look at the manuscript, be prepare to think about neuronal activity differently than you are used to. You will need to make mental images of closed feedback loops, systems permeable to their environments at all levels of their organization, and components controlling properties of other components. You will also need to exercise the thoughts of certain components located low on the hierarchy, such as genes, induce cybernetic knowledge of other components located higher on the hierarchy, such as the sensory-motor loops. The manuscript provides a general theory of what it takes for such adaptive systems to achieve biological-like intelligent behavior. The paper is available at arXiv.org <http://arXiv.org> but it can also be downloaded from my website: http://www.danko-nikolic.com/practopoiesis/ Also, the manuscript has began its search for a home in a journal. (It will need some luck, so you may well wish it a good luck.) Suggestions for improvements and feedback are most welcome.

two listings
by Levin Kuhlmann 16 Mar '14

16 Mar '14

Dear comp-neuro, I have two submissions for listing on comp-neuro. They are pasted below. Cheers, Levin Kuhlmann, PhD Centre for Neural Engineering Department of Electrical and Electronic Engineering The University of Melbourne Parkville VIC 3010 & Brain Dynamics Lab Brain and Psychological Sciences Research Centre Swinburne University of Technology Hawthorn VIC 3122 Australia Ph: +61412552283 Email: levink(a)unimelb.edu.au<mailto:levink@unimelb.edu.au> Submission 1: 10 PhD scholarships in the ARC Training Centre in Biodevices The ARC Training Centre in Biodevices at Swinburne University of Technology in Melbourne Australia has 10 PhD scholarships on offer for motivated and capable students to enter its advanced PhD program designed to develop future leaders in the medical device industry. Participants will be outstanding students drawn from the disciplines of engineering, science, medicine, design and ICT, or recent graduates with relevant business or technology innovation experience. Students will have the opportunity to participate in a structured three year PhD program that links their core research activities with skills development in areas relevant to the medical device industry. Students will spend at least one third of their time within industry environments. In addition, students will also have the opportunity to take units from Swinburneâ€™s Masters in Entrepreneurship and Innovation during their first year. With respect to neural engineering, potential projects lie in the applications of the development of software and/or hardware for electroencephalography-based depth of anaesthesia monitoring, such as dry electrodes, or the development of implantable bionic devices to better diagnose and treat epilepsy. Information can be found at the following links: http://www.swinburne.edu.au/biodevices/ http://www.swinburne.edu.au/science-engineering-technology/biodevices/postg… The deadline to apply is March 31st 2014. International students are required to sit an IELTS test (or equivalent, e.g. TOEFL) with an average band score of at least 6.5, with no band less than 6.0. Swinburne also strongly encourages minorities and women to apply. Interested applicants should email Prof. David T. J. Liley at dliley(at) swin.edu.au. -- Prof David Liley ARC Training Centre in Biodevices and Brain and Psychological Sciences Research Centre Swinburne University of Technology P.O. Box 218 Hawthorn VIC 3122 Australia ph: +61 3 9214 8812 Submission 2: Seeking PhD student to study human brain networks underlying anaesthesia and consciousness The Brain Dynamics Unit in the Brain and Psychological Sciences Research Centre at the Swinburne University of Technology is seeking a motivated and capable PhD student to work on the functional neuroimaging of anaesthetic action. The planned project, to be performed in collaboration with anaesthetists, will involve the administration of the dissociative anaesthetic agents xenon (a noble gas) and nitrous oxide ('laughing gas') to healthy participants while simultaneous MEG and EEG is recorded. The induced changes in the functional architecture of the recorded electromagnetic activity will then be characterised using a range of existing and to be developed information theoretic, graph theoretic and non-linear methods. Attempts to account for any induced changes in terms of mean field/mass action models of brain electrical activity will be investigated. The dissociative anaesthetic agents are of particular interest because they are reported to increase activity in the brain in addition to targeting glutamatergic neurotransmitter systems implicated in the pathogenesis of a number of psychiatric and neurological disorders. The position is suitable for those entering the field of neuroscience from other appropriate backgrounds - e.g., from theoretical physics - since comprehensive skills in applied mathematics and scientific programming are required. In this case the necessary neuroscience training will be provided "on the job" during the first year. Interested applicants should have a strong background in any of the following disciplines: theoretical physics, mathematics, biomedical or electrical engineering or quantitative biology. A first class honours degree or equivalent is required with proficiency in more than one of the following: C, Fortran, Python or Matlab Researchers in the unit, led by Prof David Liley, have developed a physiologically motivated theory of the dynamical genesis of the electroencephalogram (EEG). The model accounts for the rhythms of the human EEG and predicts their alteration by a range of pharmaceutical agents, in particular that of anaesthetic and sedative agents. Numerical solutions of the model's coupled set of non-linear partial differential equations have revealed spatio-temporal structures similar to those observed in experiment. It is hoped that this model can contribute to our understanding of how anaesthetic agents modulate brain activity. The Brain Dynamics group is part of the Brain and Psychological Sciences Research Centre (BPsyC), a vibrant, multi-disciplinary team of researchers whose expertise spans several different fields that include physics, psychology, psychophysiology, biophysics and the neurosciences. The BPsyC has among the most comprehensive suite of functional neuroimaging facilities available in Australia. These facilities include a 306 channel Elekta TRIUX MEG system, a Siemens 3T TIM Trio MRI and multiple high density EEG systems. A range of scholarships for national and international students are available, at up AUD 24,653 per year for three and a half years, tax-free. The deadline for applications is the 30th May 2014. More details on the application process can be found at http://www.research.swinburne.edu.au/research-students/scholarships/. International students are required to sit an IELTS test (or equivalent, e.g. TOEFL) with an average band score of at least 6.5, with no band less than 6.0. Swinburne also strongly encourages minorities and women to apply. Interested applicants should email Prof. David T. J.
