POSTDOC in SPINAL CORD INJURY IMAGING AND MODELING
by Andre Longtin 05 Jun '14

05 Jun '14

We seek a postdoctoral candidate to work on MRI image analysis and modeling of spinal cord injury. The candidate would be put forth for the Rick Hansen Fellowship described below. The successful translation of spinal cord repair therapies from animal models to the clinic requires an improved understanding of the injured motor and sensory tracts in humans. While histological tract tracing in animals can delineate the specific injured tracts and allow for therapy evaluation, these tracing methods cannot be applied to patients. Conventional magnetic resonance imaging (MRI) techniques allow spinal cord injury to be imaged; however they do not permit clinicians to reliably determine motor or sensory function. This limitation is due to the fact that conventional MRI imaging results are known to have poor correlation patient motor or sensory tract injury. Our objective is to develop an MRI technique that utilizes techniques such as diffusion tensor imaging (DTI), tractography and functional MRI imaging techniques as a biomarker. This will permit more detailed imaging of the spinal cord and allow improved correlation with neurological function. These improved imaging techniques can then be developed to improve correlation with patient clinical function which can then be used to improve the development and selection of successful therapeutic repair strategies in humans with spinal cord injury. The research consists in developing MRI imaging techniques such as DTI, tractography and functional MRI measures as a stand alone or complementary biomarker that correlates with specific motor or sensory tract function in humans. A large DTI dataset has been compiled from a variety of human spinal cord lesions. The candidate will quantify the level of damage and relate it through modeling and statistical analysis to the observed clinical scores. The DTI and tractography analyses will then be optimized to produce a strong biomarker. The candidate must hold a PhD degree in a relevant field, and will be co-supervised by a team of three investigators: Eve Tsai, a spinal cord neurosurgeon at the Ottawa Hospital Research Institute and University of Ottawa Faculty of Medicine; Andre Longtin, Physics and Medicine, University of Ottawa, a specialist in neural modeling, and Ian Cameron, a senior MRI medical physicist at the OHRI and University of Ottawa. Ideally the candidate would be able to start as soon as possible after receipt of a positive answer (typically within a month or two of being nominated), and no later than December 1st 2014. Applications consisting of a CV should be submitted to alongtin(a)uottawa.ca<mailto:alongtin@uottawa.ca> before June 25 2014 in time for submission of the file of the selected candidate to the Rick Hansen Institute.

New code repository for Comp Neuro undergrad course materials
by Rob Clewley 03 Jun '14

03 Jun '14

Hi, I have taught two introductory comp neuro classes based mostly on Hugh Wilson's great book, with some additional material from Izhikevich's recent book. The course is intended to be a very practical introduction to the basics of DEs and dynamical systems for modeling neural systems. It focuses on electrophysiology of single neurons and small networks, and is split between lecture and lab format. I have updated a lot of the codes from Wilson's book and put them into PyDSTool, or at least in Python. I never got the chance to rigorously organize these codes, but have decided to post them on github as they are because I've already been contacted by some instructors who wanted to to use PyDSTool for their comp neuro class. There are some homework and project ideas up there too. Feel free to fork and contribute on github for others to benefit from any further input. https://github.com/robclewley/compneuro http://www.ni.gsu.edu/~rclewley/Teaching/CompNeuro/NEUR4030.html Best, Rob -- Robert Clewley, Ph.D. Assistant Professor Neuroscience Institute and Department of Mathematics and Statistics Georgia State University PO Box 5030 Atlanta, GA 30302, USA tel: 404-413-6420 fax: 404-413-5446 http://neuroscience.gsu.edu/rclewley.html

[PhD] Natural scene statistics and visual motion processing in humans and non-human primates
by Laurent Perrinet 03 Jun '14

03 Jun '14

Dear List, Applications are invited for 3 PhD positions funded by the PhD program in Integrative and Clinical Neurosciences (http://www.int.univ-amu.fr/PhD-Program-in-Integrative-and), as described in: http://www.int.univ-amu.fr/IMG/pdf/List_of_research_projects.pdf among which the following ---at the Institute of Neurosciences, Timone in Marseille, France--- may be of interest to the list. Deadline for applications is June 15th. Cheers, Laurent -- Laurent Perrinet - INT (UMR 7289)/CNRS http://invibe.net/LaurentPerrinet Title: Natural scene statistics and visual motion processing in humans and non-human primates Supervisor: Guillaume MASSON Laboratory: Institute of Neurosciences, Timone (INT) State of the art: The mammalian visual system is tuned to process the complex, high-dimension statistics of natural scenes. For instance, neuronal responses to natural inputs are more ﬁnely tuned, more temporally precise and more sparse. A major challenge is to understand how such complex information is integrated to measure perceptual quantities such as object motion in a crowded environment. From a theoretical perspective, this implies to understand how the cascade of cortical processing steps extracts the relevant dimensions through linear (e.g. ﬁltering) and nonlinear (e.g. gain control, contextual modulation) mechanisms. From an experimental perspective, the challenge implies to design behavioural tasks that can dissect out these mechanisms. The classical approach is to compare classic, low-dimension stimuli such as gratings or dots with natural images. However, it is almost impossible to parametrize natural scenes in a useful way. We [1], and others [2], have designed and begun to use naturalistic stimuli as static or dynamic textures of which mean and variance along each parameter space is manipulated to demonstrate how sensory systems sense and represent information. We have recently shown in Nature Neuroscience3 that richer textures drive more accurate and reliable ocular tracking responses. This is the ﬁrst demonstration that naturalistic inputs processing can be probed using sensorimotor tasks. Objectives: Our objective is to demonstrate that in human and non-human primates, estimating direction and speed of a moving object requires to integrate information from the multiple spatial and temporal scales existing in natural scenes. We will investigate how different spatiotemporal frequency channels are nonlinearly combined to drive faster and more precise tracking eye movements. In particular, we will extend our previous study [3] by studying how richness of visual motion information reduces the variability of motor responses, within and across trials. We will also study how the geometric organization of the texture input impacts performance, opening the door to understanding the link between low-level motion processing and the perceptual organization of complex scenes. Methods: The approach is based on probing low-level visual processing through the dynamics of reﬂexive eye movements. Ocular following responses exist in both humans and non-human primates and over the last 15 years we, and others have shown how they can probe low-level motion mechanisms. The PhD will work in non-human primates to conduct behavioural experiments using random phase textures and recording eye movements with the scleral search coil technique. Behavioural performance will be assessed through kinematics (acceleration, latency…) as well as through detection and discrimination tasks (i.e. comparison between responses for two stimuli). Expected results: A ﬁrst step will be to reproduce the main observation made in humans: richness of the inputs improves precision and decreases variability. Then we will characterize the nonlinear interactions between spatiotemporal channels underlying speed estimation through motion energy and their temporal dynamics. Feasibility: This project is supported by an ANR project (SPEED) that started in October 2013. The PhD student will work in close collaboration with a PD fellow working in humans as we expect the ﬁrst series of experiments to be identical in both species. A non-human primate set-up is available and a research assistant (F Barthelemy) will daily supervise the lab work. The InViBe team has strong expertises in modelling and electrophysiology so that the project will open the door for collaborative work in texture synthesis and speed processing modelling with Laurent Perrinet and recording of population activity evoked with dense, naturalistic textures with Fred Chavane. 1 Sanz-Léon et al.

[meetings] [ECCV2014] CfP: Second Workshop on Affordances: Visual Perception of Affordances and Functional Visual Primitives for Scene Analysis (in conjunction with ECCV 2014)
by Karthik Mahesh Varadarajan 02 Jun '14

02 Jun '14

========================================================================== *Call for Papers- Second Workshop on Affordances: Visual Perception of Affordances and Functional Visual Primitives for Scene Analysis* (in conjunction with ECCV 2014), September 7, 2014, Zurich, Switzerland http://affordances.info/workshops/ECCV.html ========================================================================== The workshop seeks to address key challenges in computer vision and applications such as robotics with regard to functional form descriptions, which are termed as "affordances". 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 researchers to build visual perception and behavioral algorithms in recent years. This workshop attempts to explore this nascent, yet rapidly emerging field of affordance based cognitive vision (recognition of objects, activities, scenes etc.) while integrating the efforts and language of affordance communities not just in computer vision, 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 algorithms leading to various intelligent applications. The workshop will also feature 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 and 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 - Affordance learning - Affordance ontologies - Knowledge bases for affordances and affordance modeling Understanding various challenges in the field of affordances and building a common language and framework for communication across the varied affordance communities 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. *Paper Submissions* Paper contributions to the workshop are solicited in four different formats. This departure from the regular format is intended to promote greater contribution and cater to the needs of affordance communities from various disciplines such as Knowledge Representation, Psychology, Psychophysics, Neuroscience, Kinematics, Ontologies besides traditional audience such as from Cognitive/ Computer Vision and Robotics. - *Conceptual papers* (2 pages): 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* (6 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* (6 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* (14 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 ECCV formatting guidelines (Templates: LaTeX <http://eccv2014.org/wp-content/uploads/2013/10/eccv2014kit.zip>). All contributions are to be submitted via Microsoft Conference Management Tool <https://cmt.research.microsoft.com/A22014/Default.aspx> in PDF. 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. Hence, while early submissions will have a better chance of acceptance than late submissions, submission to either (or both) rounds is equally encouraged. *Important Dates* - Initial submissions (Early): 23:59:59 PDT *Jun 10*, 2014 - Notification of acceptance (Early submissions): June 20, 2014 - Initial submissions (Late): 23:59:59 PDT June 25, 2014 - Notification of acceptance (Late submissions): July 15, 2014 - Submission of publication-ready version: July 25, 2014 - Workshop date: September 7, 2014 *Organizers* Karthik Mahesh Varadarajan <http://www.karthikmahesh.com> (varadarajan(at) acin.tuwien.ac.at), TU Wien Alireza Fathi <http://ai.stanford.edu/~alireza/> (alireza(at)cs.stanford.edu), Stanford Juergen Gall <http://www.vision.ee.ethz.ch/~gallju/> (gall(at) iai.uni-bonn.de), Univ.

Real-life cognition contest (submission deadline Nov 1 2014)
by Michael Hanke 02 Jun '14

02 Jun '14

In order to fully understand how the brain works, it is essential to study the complex inter-play of cognitive processes that are characteristic when interacting with a rich natural environment. Going beyond the localization of individual aspects of brain function is pivotal as there are clear limits to what we can learn about the function of the brain as whole via restricting investigation to specialized cognitive sub-systems in feature deprived laboratory settings. We believe that there is need for more publicly available data on real-life cognition, as well as analysis strategies to study complex concurrent neural processes. We invite research groups and individuals to participate in a contest to master these challenges. As a starting point, we have published a large dataset (functional MRI, simultaneous cardiac and respiratory measurements, technical noise estimates, high-res structural images (T1w, T2w, SWI, angiography, DTI), and stimulus annotations) that is available to anyone without restrictions: Hanke, M., Baumgartner, F.J., Ibe, P., Kaule, F.R., Pollmann, S., Speck, O., Zinke, W. & Stadler, J. (2014). A high-resolution 7-Tesla fMRI dataset from complex natural stimulation with an audio movie. Scientific Data, 1. doi:10.1038/sdata.2014.3 Among all submissions that are received until November 1 2014 a jury will determine the best contributions in terms of novelty of the approach, scientific rigor, and potential impact on future research and application. The best three contributions will receive an award (3000, 1500, and 500 Euro respectively) sponsored by the Center for Behavioral Brain Sciences, Magdeburg, Germany. The jury consists of: Uri Hasson (Princeton University) James Haxby (Dartmouth College) Daniel Margulies (MPI Leipzig) Russ Poldrack (U Texas, Austin) Jean-Baptiste Poline (Neurospin) Stefan Pollmann (CBBS, Magdeburg) Peter Ramadge (Princeton University) For more information, demos, and data access visit: http://studyforrest.org
