Spectrum of power laws for curved hand movements

by Terry Sejnowski

Spectrum of power laws for curved hand movements Dongsung Huh and Terrence J. Sejnowski http://www.pnas.org/content/early/2015/07/02/1510208112.abstract In curved hand movements around ellipses, the speed tends to scale inversely with the curvature with a power law having an exponent of -1/3. We examined whether this well-known regularity in motor planning holds for more general shapes. Using an optimality principle, we identified a set of basis shapes, each with a single characteristic angular frequency, which subjects drew with power laws whose exponents ranged from 0 to -2/3. More general movements exhibited linear mixtures of power laws. The speed of arbitrary doodling movements with a broad spectrum of frequencies could also be predicted from the curvature with high accuracy. Terry -----

New computational challenge on Big Data and neurodegenerative diseases

by Neta Zach

Prize4Life, Sage Bionetworks and DREAM are proud to announce the launch of The DREAM ALS Stratification Prize4Life Challenge <https://www.synapse.org/#!Synapse:syn2873386/wiki/>. The prize, is a computational challenge inviting bioinformatics, statisticians, computation geeks and math geniuses to work on the PRO-ACT database and identify meaningful subgroups of ALS patients. The challenge offers a $28000 prize and journal partnership with Nature Biotechnology. You can read more about it here <http://www.jpost.com/Business-and-Innovation/Health-and-Science/Israel-base…> or join our Webinar about it on Wednesday <https://attendee.gotowebinar.com/register/2656120293543998721> July 8 at 11am EST. While most ALS patients die with 3-5 years, but some patients, like Stephen Hawking, survive much longer. What differentiates the Stephen Hawkings from the Lou Gehrigs? Is ALs one disease or several sub-disease? the challenge invite participants to devleop algorithms that can stratify the ALS patient population into meaningful subgroups with distinct features. You can read more about it here <http://www.jpost.com/Business-and-Innovation/Health-and-Science/Israel-base…> . A previous Challenge, the ALS Prediction Prize <http://www.innocentive.com/prize4life-announces-50000-als-prediction-prize-…> which ran in 2012, using only a small subset of the full database, led to the creation of solutions that are able to reduce by 20% the number of patients needed for effective ALS clinical trials, a millions of dollars reduction in the costs of each future ALS clinical trials and are used by several drug companies. Furthermore, the Challenge’s winning algorithms identified novel features of ALS pathology that are predictive of disease progression. The Challenge summary was published in Nature biotechnology <http://www.nature.com/nbt/journal/v33/n1/full/nbt.3051.html> and were also covered by Science News <http://news.sciencemag.org/brain-behavior/2014/11/crowdsourcing-project-pre…> , Science Translational Medicine <http://stm.sciencemag.org/content/6/264/264ec204.full> and a News and views piece in Nature biotechnology <http://www.nature.com/nbt/journal/v33/n1/full/nbt.3118.html>. The ALS Stratification Challenge aims to go beyond the prediction prize and bring us one step closer to personalized medicine- to accurately and effectively identify meaningful subgroups of diverse ALS patients and the predictive models and features specific to these subgroups. Winners will win $28000 and the winning submissions with be published with a journal partnership from Nature Biotechnology.

PhD positions at LMU Munich

by Stefan Glasauer

Two PhD positions are available at Ludwig-Maximilians-Universität (LMU) München for a fixed term of 36 months, starting 1st September 2015. Both positions are linked to the research projects “Dynamic prior and contextual calibration”, which is a part of the newly funded German research group “active perception”. The project aims to uncover the mechanism underlying dynamic contextual calibration in multimodal environments, and to develop a general Bayesian framework describing the prior updating mechanisms in contextual calibration. In particular, we plan to focus on central tendency effects (for a review, see Shi, Church & Meck, 2013, Petzschner & Glasauer, 2015) in multimodal magnitude estimation. The project is expected to establish a general computational framework to examine whether the brain uses multiple modality-specific priors or an amodal prior in contextual calibration, and how the brain resolves inconsistencies among priors, as well as how action priors are taken into consideration in magnitude estimation. Successful candidates should have an excellent M.Sc. degree, or equivalent (or be currently working towards one) in a field of cognitive or computational neuroscience. Computational modeling and programming skills in MATLAB and R are essential. Good verbal and written communication skills in English, interest and some experience in multi-disciplinary research are highly desirable. Successful candidates will be paid according to German salary scale 65% TVL-13. One candidate will work in Department of Psychology, LMU under the supervision of Zhuanghua Shi, and the other candidate in the Center for Sensorimotor Research, LMU under the supervision of Stefan Glasauer. Applicants should send a completed application form along with a cover letter detailing their research experience and interests, a CV and two academic references electronically to either Zhuanghua Shi (shi(a)psy.lmu.de) or Stefan Glasauer (s.glasauer(a)lrz.uni-muenchen.de) The closing date for applications is August 1st, 2015. Shortlisted candidates will be invited for interview at the beginning of August. We regret that we may not be able to respond to all applications.

Autumn school on sensorimotor foundations of social cognition

by Alexander Maye

"The sensorimotor foundations of social cognition" Autumn school Boltenhagen, Baltic Sea, Germany October 11-17, 2015 Description Sensorimotor approaches predict that social cognition does not primarily result from maintaining and running complex models of intentions and beliefs of other agents, but rather from patterns and regularities in the dynamic sensorimotor coupling between them. The school will take stock of concepts and models that follow this emerging view and illuminate them from the perspectives of relevant fields like social psychology, social cognitive neuroscience, robotics and philosophy of mind. Tangible outcomes of the school will be a set of articles on selected aspects of sensorimotor accounts of social cognition which will be authored by the participants and published in Scholarpedia (scholarpedia.org) The school will be the first in a series which is funded and organized by the EU H2020 project "Socializing sensorimotor contingencies - socSMCs" (socSMCs.eu). This year the school is organized by the Dept. of Neurophysiology at the University Medical Center Hamburg-Eppendorf (uke.de/neurophysiology). The registration fee is 300Ä and covers participation in the school, accommodation in a single room, breakfast, lunch and three dinners. A reduced fee of 200Ä is requested from participants willing to share a double room. Participants will have to cover their own travel expenses. Content The five-day school will be structured around the following themes: * Enactive and embodied views on social cognition * Non-reductionist, interaction-based approaches to social cognition * Entrainment vs. emulation and mindreading * Dynamical systems theory and social cognition * Neural mechanisms of social interaction: toward a second-person neuroscience * Mutual prediction and adaptation in social interaction * Motor resonance during human-robot interaction The school will comprise keynote lectures in the mornings and discussion groups in the afternoons which serve for in-depth discussions of topics from the keynote lectures.
