Dear all, Dr Pulvermuller will be giving a talk on Thursday the 1st of March at 4PM at YNic (tomorrow). Here goes his abstract Early time course of psycholinguistic information access in the brain as revealed by neurophysiological imaging (EEG and MEG) Friedemann Pulvermüller, MRC Cognition and Brain Sciences Unit, Cambridge, UK, friedemann.pulvermuller(a)mrc-cbu.cam.ac.uk The main stream view in neurophysiological psycholinguistics has been that relatively late components of the brain response with latencies of 300-500 ms reflect higher stages of language processing, such as lexical access, semantic processing and context integration. This view is in contrast with data from psycholinguistics indicating very early psycholinguistic information access. Why, then, would ERP studies reveal late neurophysiological effects, but not the early ones psycholinguistic behavioral work would suggest? As language stimuli are very variable physically and psycholinguistically, the early components of the linguistic brain response, which are both focal and short-lived, may fall victim to the neurophysiological reflection of such stimulus variance [1]. Studies keeping stimulus variance to a minimum [2-3] or using new paradigms and analysis techniques [4-5] reported early (<250 ms) near-simultaneous effects of lexical and semantic processing in word recognition. The talk will discuss these effects, using neurophysiological data to judge linguistic models of the time course of psycholinguistic information access. A neurobiological model will be used to account for both the near-simultaneity of psycholinguistic information access as well as the minimal time delays observed. Distributed cell assemblies with specific cortical topographies binding information about word form and meaning may be the basis of near-synchrony and precise spatio- temporal patterning [5-7].

YNiC Closing at 5pm today

by Mark Hymers

The YNiC open plan area will be closing at 5pm today as we need to perform some IT maintenance which cannot be done with users present. We will open again as normal tomorrow (Friday) morning. Apologies for the short notice. Mark -- Mark Hymers York Neuroimaging Centre

Friedemann Pulvermuller

by Silvia Gennari

Dear all, There will be a talk by Friedemann Pulvermüller (MRC-CBU) on Thursday the 1st of March at 4PM at the YNic. Dr. Pulvermüller will be teaching Advanced Neuroimaging to the master students (CNS) earlier in the day and has kindly agreed to give a second talk for a more general audience. Dr. Pulvermüller works in cognitive neuroscience of language and has written extensively on the topic. He has used fMRI, TMS and MEG techniques to ask question about both time course and localization of brain activity during language processing. He has also investigated neuropsychological issues such as aphasia. Here is a link to his website http://www.mrc-cbu.cam.ac.uk/people/people-pages.php?id=105 Everybody is welcome.

Re Use of the Biocentre facilities at YNiC

by Gary Green

Apologies to anyone who this may not concern. We have had another complaint from the receptionist of the Biocentre who is passing on the other tenants views. We are being asked not to use the kitchen facilities to socialise and there should be no more than two people in there at any one time. The other tenants are especially upset as the kettle has been broken and that we are using their coffee amongst other things. As you can imagine this has caused problems as the biocentre rely on the receptionist for catering for meetings. We rely on the goodwill of the receptionists in the Biocentre and problems of this kind could damage the long term benefits we get from working with them. Please can I ask users not to use the kitchen next to reception. There is a kitchen along the corridor in the glassed roof area. DO NOT use other people's milk/coffee/food/cutlery/bowls etc YNiC will put a kettle in the meeting room in the MRI corridor. While we are on the subject I would also like to add that YNIC has visits regularly and the standards of the open plan have started to drop dramatically again, I and other members of the team do not have time to clean up after users on a morning. The cleaners are not here to tidy up coffee cups etc, or rearrange furniture. Please leave the open plan area and desks as you find them ready for the next person. If you have cups with liquid still in you can empty this in the sink in MRI corridor. Please flush the fluids away after you.

Dear all, Sorry if you receive this message twice. Masters students in Cognitive Neuroscience will be giving presentations at YNic tomorrow and next Thursday at 4PM. They will present the research they are planning to conduct during the summer. Everyone is welcome. The schedule is as follows Thursday February 15th 4PM - Is it a face or a house? Using binocular rivalry to investigate visual awareness (supervisor: Tim Andrews). Pippa Baird Jenny Cox 4.15PM - Do specialized visual areas really exist in the human ventral stream? (supervisors: Tim Andrews and Tom Hartley) Alex Clarke Phil Pell 4.30PM - Representing actions through language (supervisor: Gennari) Claire Moody (Veronica) Tzu-Hui Chuang Thursday - February 22nd. 4PM - What is the difference between familiar and unfamiliar face perception? (Tim Andrews) Jodie Davies Spyroula Spyrou 4.15PM - Hemispheres and handwriting: an MEG project (Andy Ellis) Nuria Donamayor Alonso 4.30 PM - Localisation of auditory function with fMRI and MEG (Quentin Summerfield) Emma Knowles Sam Matthias 4.45PM -Brain functional connectivity from MEG data (Gary Green) Dave Cole Chris Neale John Griffiths Lisa Brindley Alana James Silvia Gennari Department of Psychology University of York York, YO10 5DD United Kingdom
