Chromium web browser
by Paul Elliott 19 Mar '15

19 Mar '15

Hi all, Debian, who provide the base operating system that we use at YNiC, recently announced[1] that the Chromium web browser will no longer receive security updates. As a result we will be removing the Chromium browser from all our systems on Friday next week (27th March) so that we're not left exposed to security problems with Chromium. Anyone using Chromium at YNiC should switch to Iceweasel (a rebranded Firefox browser) as this will continue to receive security updates. If you have any bookmarks in Chromium that you would like to save please follow the steps below: * Run Chromium and press CONTROL+SHIFT+O to bring up the bookmark manager. * Click on the Organize button and choose 'Export bookmarks to HTML file...' * Choose a sensible filename and click the save button. * Close Chromium and open Iceweasel. * Press CONTROL+SHIFT+O to bring up the library window. * Click the 'Import and Backup' button and select 'Import Bookmarks from HTML...' * Choose the file saved in the previous step and click the Open button. All your bookmarks from Chromium will now be saved in Iceweasel. If you have any problems saving your bookmarks or if you have a use case that Iceweasel fails to satisfy please let us know by e-mailing it-support(a)ynic.york.ac.uk as soon as possible. Thanks, Paul. [1] https://lists.debian.org/debian-security-announce/2015/msg00031.html -- Paul Elliott, UNIX Systems Administrator York Neuroimaging Centre (YNiC), University of York

YNiC seminar today
by rem 19 Mar '15

19 Mar '15

Dear Users This afternoon (from 4 pm in B020), there will be two internal project proposal presentations from Jonny Smallwood's group: * 1) Differences between the Default Mode Network's activity during self-relevant and not-self-relevant memory formation * Irene de Caso *2) Window to the wandering mind - an fMRI investigation on the role of pupil dilation in the occurrence of self-generated thought* Mahiko Konishi Abstract Occurrences of mind-wandering, i.e. shifting our attention from the external environment to our self-generated thoughts, are spontaneous, dynamic experiences that clearly illustrate the fleeting identity of consciousness. Due to its subjective nature, first-person point of view measures like self-reports and experience sampling, such as stopping a participant in the middle of a task and asking him if he was focused on the task or distracted, have long been the state of the art for the study of self-generated thought. These methods, while managing to capture instances of this experience, lack of a way to objectively gauge occurrences of self-generated thought from a second- or third-person point of view without disrupting the experience itself. As there is previous evidence that pupil dilation tracks fluctuations in mind wandering and that these are also linked at a neural level with the activation of the Default Mode Network, we aim to bring the two methods together in order to triangulate (with the help of experience sampling) the temporal dynamics of self-generated thought. Everyone is welcome to attend and refreshments will be available after the seminar. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

Important: Presentation and MRI synching
by Andre Gouws 16 Mar '15

16 Mar '15

This affects: fMRI users using pulses from the MRI scanner with the Presentation software package Does not affect: fMRI users who do not use pulses from the scanner or who use PsychToolbox / Psychopy. For users who do use Presentation with MRI trigger timing, please see the instructions for changing your experiments to use the new, more reliable trigger capture device. These changes should be made immediately as the system is now active. https://www.ynic.york.ac.uk/docs/TechInfo/Misc/ParallelPort#MRIPresentation The changes are minor and should only take a minute to implement. Any trouble or confusion, please contact me directly. -- Andre' ************************************************************************ Andre Gouws York Neuroimaging Centre University of York The Biocentre York Science Park Heslington YO10 5NY Tel: +44 (0) 1904 435327 Fax: +44 (0) 1904 435356

Dear all, I am pleased to announce that *registration is now open* for the official SPM course covering fMRI/MRI/VBM in London. It will be held Thursday 14^th May to Saturday 16^th May 2015 (directly after the SPM for MEG/EEG course, which will be held at the same venue). To register, please visit http://onlinestore.ucl.ac.uk/browse/extra_info.asp?compid=1&modid=2&deptid=… . (Please note that all attendees must register via that link – even if they previously filled in the “pre-registration” form.) The course is organised by the Methods Group at the Wellcome Trust Centre for Neuroimaging (“the FIL”), where SPM is developed. The three-day course will be divided into theoretical sessions covering experimental design and statistical inference and practical sessions in which SPM12 will be used to analyse exemplar data sets. This course is suitable for both beginners and more advanced users, with topics including image pre-processing, the general linear model (GLM), voxel-based morphometry (VBM) and Dynamic Causal Modelling (DCM). The programme for the course is below. Kind regards, Peter.

Fwd: Faculty Position in Educational Neuroscience and Psychology
by Gary Green 14 Mar '15

14 Mar '15

The Centre for Research and Development in Learning (CRADLE) and the Division of Psychology, School of Humanities and Social Sciences, Nanyang Technological University (NTU) invite applications for a tenure-track Assistant Professorship in Educational Neuroscience and Psychology. CRADLE@NTU serves as an activity and technology incubator for researching and transforming learning in higher education. The mission of CRADLE is to integrate research in Neuroscience, Psychology, Pedagogy and Technology to inform learning and education. We believe that transformative innovation can happen at the nexus of these different fields. Our research strands provide synergies between these disciplines in the hopes such collaborative efforts may give way to a New Science of Learning. The Division of Psychology at Nanyang Technological University is a relatively young program with a cohesive faculty dedicated to high-quality research and teaching. The Division was recently ranked 45th in the world (http://www.topuniversities.com/university-rankings/university-subject-ranki…) and has seen continued growth in recent years. For further information about the Division, please refer to the following website: http://www.hss.ntu.edu.sg/Programmes/psychology/Pages/Home.aspx The successful candidate will be involved centrally in a new research program in Educational Neuroscience within CRADLE to conduct research in the study of thinking and/or the neuroscience of learning. For the study of thinking, research will involve translation of the study of thinking into learning design and solutions for higher education settings, including the use of eLearning and learning analytics. The research in the neuroscience of learning (cognitive or affective) will aim to bridge findings from educational neuroscience to educational strategies. Candidates with a PhD in Psychology/Neuroscience and post-doctoral research training and experience in one or more of the following research areas involving human subjects are encouraged to apply: educational neuroscience, cognitive/affective neuroscience, computational neuroscience, translational neuroscience and cognitive neuropsychology. The successful candidate will hold both an appointment as an investigator in CRADLE as well as a tenure track faculty position in the Division of Psychology. He/she will have the opportunity to establish an independent research program with possible access to behavioral labs and various neuroimaging facilities (MRI/EEG/MEG/NIRS/TMS). Research on the development of individual differences in learning and thinking is of particular relevance in young and older adults. Salary will be competitive and will commensurate with qualifications and experience. The University offers a comprehensive fringe benefit package. Information on emoluments and general terms and conditions of service is available at http://www.ntu.edu.sg/ohr/CareerOpportunities/TermsandConditions/Pages/Facu…. Application Procedure To apply, please refer to the Guidelines for submitting an Application for Faculty Appointment (http://www.ntu.edu.sg/ohr/CareerOpportunities/SubmitanApplication/Pages/Fac…) and email your application package (consisting of a cover letter, curriculum vitae, personal particulars form, teaching and research statements, three selected reprint/preprints of publications, and the names and email addresses of three potential referees) to: Charmaine.goh(a)ntu.edu.sg Review of applications will begin upon receipt and will continue until the position is filled.
