Hi, The UPS in the YNiC server room will be undergoing its yearly maintanence tomorrow from around 11:30. This should have no effect on users unless we suffer from a power cut at exactly the same time as the UPS is being maintained (a highly unlikely scenario). In this case, there will be a short outage whilst we bring the servers back up again. Thanks, and sorry for the short notice. Mark -- Mark Hymers York Neuroimaging Centre

Freesurfer
by Mark Hymers 28 May '11

28 May '11

Hi, FreeSurfer has recently announced a new version (5.1.0) where they've finally sorted out the license issues after several years. We don't have packages built for it yet, but will be looking at it very soon (in conjunction with the neurodebian team) to replace the semi-working 4.5.0 packages we have now. Release notes can be found at: http://surfer.nmr.mgh.harvard.edu/fswiki/ReleaseNotes Thanks, Mark -- Mark Hymers York Neuroimaging Centre

YNiC seminar today
by Rebecca E Millman 25 May '11

25 May '11

Dear Users Today (4-5 pm in YNiC) there will be a YNiC project proposal presentation given by Chris Racey. The title of the talk is "The effects of parametrically manipulating view exposure range on representational invariance in object selective cortex". Please see the abstract below. Everyone is welcome to attend. N.B. The starting time of the YNiC seminars will be 4 pm this term. Best wishes Rebecca *Abstract* Previously we have carried out two experiments in which view shift of objects and landscape scenes was parametrically manipulated. In both experiments participants viewed blocks of stimuli changing in view by 0, 5, 10, and 15°. Different levels of adaptation across these view shift conditions allow us to derive a measure of view sensitivity for any given voxel or region. We were able to show variation in the degree of view sensitivity between category selective regions for both objects and landscape stimuli. Our previous work has shed new light on how category specific visual information is processed and represented during perception. However, it is not yet clear what the effect of object learning and long term storage is on these ventral stream representations. Previous research on this issue is limited, and there have been few studies investigating the effects of prior learning on neural adaptation. We aim to apply our parametric manipulation of view shift paradigm during an encoding experiment with unfamiliar objects prior to scanning. Participants will under training, and learn to recognise objects where their range of view exposure will vary parametrically, from 0°, 10°, and 20°. In the scanner, all of the stimuli will be presented from previously unseen views in an fMR-adaptation block design, with blocks of images shifting in view in 10° steps. For each pre-exposure condition, the presentation conditions in the scanner will be identical, and any differences across conditions must be due to differences during the encoding of items. We predict that objects learned with a greater range of views will be associated with richer, more invariant, representations, and show greater degrees of invariant adaptation than objects learned under a narrower range of views. -- Dr. Rebecca E.

[Fwd: [SPM] Vacancy for one postdoc and one PhD student in Leuven, Belgium]
by Gary Green 23 May '11

23 May '11

FYI --------------------- We are looking for two bright and motivated researchers to work on a research project in which we will use *brain imaging and advanced brain decoding methods to investigate the neural basis of deviant mental representations in neurodevelopmental disorders such as autism, dyslexia, and dyscalculia*. This project is an interdisciplinary collaboration between the Laboratory of Biological Psychology (Hans Op de Beeck), the Parenting and Special Education Research Group (Bert De Smedt), and Child Psychiatry (Jean Steyaert, Bart Boets), all part of the University of Leuven (K.U.Leuven) in Belgium. We offer one PhD position and one Post-doc position. Eligible candidates should have or should soon obtain a master’s degree (for the PhD position) and a PhD (for the postdoc position) in a relevant field such as neuroscience, psychology, psychiatry, neurobiology, or medical engineering. Specific positive points for the evaluation will be experience with brain imaging (in particular functional magnetic resonance imaging), a computational background in a relevant field (e.g., brain imaging data analysis, neural networks, etc.), and good computer skills (e.g., Matlab). A background in neurodevelopmental disorders is a plus, but not mandatory. Good English (oral and written) communicative skills are necessary. The two positions are full-time, for a period of 4 years (PhD position) and 2-3 years (postdoc), and start in October 2011. The two positions are strongly research oriented, and teaching and/or administration load will be minimal. The research will be embedded in a very stimulating environment with state-of-the-art technical facilities and with ample opportunities for interaction with experts on neurodevelopmental disorders and brain imaging. The K.U.Leuven is consistently ranked within the top of European Universities and is located in the city of Leuven, which has an strong international appeal. For more information about our university, please visit http://www.kuleuven.be/about/ Formal applications should be sent by email to Hans Op de Beeck, and should include a scientific CV (mentioning past research positions and education, and publications), motivation letter, and the names and contact information of 2 senior researchers that are willing to write a recommendation letter if necessary (no letters have to be sent yet). Application deadline is June 20^th 2011. For further information please contact Hans Op de Beeck (hans.opdebeeck(a)psy.kuleuven.be <mailto:hans.opdebeeck@psy.kuleuven.be>), Bert De Smedt (Bert.DeSmedt(a)ped.kuleuven.be <mailto:Bert.DeSmedt@ped.kuleuven.be>), or Bart Boets (Bart.Boets(a)ped.kuleuven.be <mailto:Bart.Boets@ped.kuleuven.be>).
