AREADNE 2016 Call for Abstracts

by John Pezaris

****** CALL FOR ABSTRACTS ****** AREADNE 2016 Research in Encoding and Decoding of Neural Ensembles 22-26 June 2016 Nomikos Conference Centre Santorini, Greece Celebrating 10 Years of AREADNE Conferences http://www.areadne.org info(a)areadne.org INTRODUCTION A fundamental problem in neuroscience is to understand how the activation of neuronal populations gives rise to higher order functions including learning, memory, cognition, perception, action and ultimately conscious awareness. Electrophysiological recordings have revealed considerable information about the firing patterns of single neurons, but it remains largely a mystery how collections of individual neurons interact to perform these functions. Understanding ensemble activity is critical to understanding the brain. CONFERENCE MISSION The AREADNE Conferences have been created to gather global scientific leaders who work on neural ensembles and establish a touch-point for the widely disparate and hybrid field. With a spectacular setting on Santorini, the conferences have been carefully planned to foster discussion and interaction between attendees to encourage the establishment of lasting professional relationships. The meetings continue our efforts to promote systems neuroscience in Greece through creating a world-class forum for cutting-edge research. For 2016, we will be Celebrating Ten Years of AREADNE Conferences! FORMAT AND SPEAKERS The conference will span four days, in morning and early evening sessions. Confirmed speakers include experts in the field of multi-neuron experiment, theory, and analysis (in alphabetic order): Michele Basso Matthias Bethge Rick Born Rosa Cossart James DiCarlo Alexander Ecker Lisa Giocomo Konrad Kording Matthew Larkum Albert Lee John Maunsell May-Britt Moser Stephanie Palmer Xaq Pitkow Michael Roukes Irini Skaliora Stelios Smirnakis Nelson Spruston Gina Turrigiano CALL FOR ABSTRACTS We are currently soliciting abstracts for poster presentation. Submissions will be accepted electronically, and must be received by 12 Feb 2016. Automated email acknowledgment of submission will be provided, and manual verification will be made a few days after submission. Notification of acceptance will be provided by 15 March 2016.

OKINAWA/OIST COMPUTATIONAL NEUROSCIENCE COURSE 2016 Methods, Neurons, Networks and Behaviors June 13 - June 30, 2016 Okinawa Institute of Science and Technology Graduate University, Japan https://groups.oist.jp/ocnc The aim of the Okinawa/OIST Computational Neuroscience Course is to provide opportunities for young researchers with theoretical backgrounds to learn the latest advances in neuroscience, and for those with experimental backgrounds to have hands-on experience in computational modeling. We invite graduate students and postgraduate researchers to participate in the course, held from June 13th through June 30th, 2015 at an oceanfront seminar house of the Okinawa Institute of Science and Technology Graduate University. Applications are through the course web page (https://groups.oist.jp/ocnc) only; January 4 - February 5, 2016. Applicants will receive confirmation of acceptance in March. Like in preceding years, OCNC will be a comprehensive three-week course covering single neurons, networks, and behaviors with ample time for student projects. The first week will focus exclusively on methods with hands-on tutorials during the afternoons, while the second and third weeks will have lectures by international experts. The course has a strong hands-on component based on student proposed modeling or data analysis projects, which are further refined with the help of a dedicated tutor. Applicants are required to propose their project at the time of application. There is no tuition fee. The sponsor will provide lodging and meals during the course and may support travel for those without funding. We hope that this course will be a good opportunity for theoretical and experimental neuroscientists to meet each other and to explore the attractive nature and culture of Okinawa, the southernmost island prefecture of Japan.

PhD Position: Modelling Gait in People with Parkinson's Disease.

by Tsaneva-Atanasova, Krasimira

PhD in Modelling Gait in People with Parkinsons Disease. Primary supervisor: Prof Krasimira Tsaneva-Atanasova<http://emps.exeter.ac.uk/mathematics/staff/kt298> Secondary supervisors: Dr Mark Wilson (University of Exeter), Dr Victoria Goodwin (University of Exeter) Based within the EPSRC Centre for Predictive Modelling in Healthcare, a £2M initiative bringing together mathematicians, statisticians and clinicians, you will work on a project aiming to develop a data-driven mathematical modeling framework in order to study gait impairments in patients with Parkinson’s. Parkinson's is a progressive neurological condition that mainly affects people of 50 and over. One person in every 500 has Parkinson's, which equates to about 127,000 people in the UK. There's currently no cure, and the range of symptoms and how quickly they progress are different for everyone. The main symptoms of Parkinson's are tremor, rigidity and slowness of movement. Despite optimal medication therapy, many people with Parkinson’s still experience gait impairments. Gait impairments (e.g., freezing of gait) are associated with falls and fear of falling, and reduced quality of life. This studentship aims to further our understanding of the degenerative nature of the disease by taking a dynamical systems approach to modelling the coordination of locomotion (gait) from an individual perspective. While many studies have examined discrete gait measures (e.g. step length) it is likely that several gait malfunctions will interact and incur a simultaneous deterioration of stepping. A dynamical systems approach is particularly useful in predicting when and if this deterioration may cross a critical threshold; for example, triggering a freeze or a stumble. The first stage of this project will be to develop a model based on gait data we have already collected from 18 people with Parkinson’s. The second stage would be to collect additional data to test model’s predictions and refine and improve the model. This project is one of a number which are funded by the Engineering and Physical Sciences Research Council (EPSRC) Doctoral Training Partnership to commence in September 2016. The studentships will provide funding for a stipend (currently £14,057 per annum for 2015/16), research costs of £3,000 and UK/EU tuition fees at Research Council rates for 3.5 years. Application Criteria Applicants should have or expect to achieve at least a 2:1 Honours degree, or equivalent, in Maths, Physics, Medicine, Natural Sciences or other numerate discipline. The closing date for applications is midnight on Monday 4 January 2016. Interview will be held at the University of Exeter is mid-late January 2016.
