Hi again, As mentioned in the earlier email about the training session, MEG will be undergoing planned maintenance in the near future. The dates are Friday 29th September until Sunday 8th October. MEG will reopen for use on Monday 9th October. Another important announcement is that we now have a bookings(a)ynic.york.ac.uk email address. This should now be used for bookings instead of emailing Claire directly as it will allow us to cover for her when she isn't around. We'll be updating the web site and documentation to reflect this as soon as we can. Cheers, Mark (on behalf of YNiC) -- Mark Hymers York Neuroimaging Centre

[ANNOUNCEMENT] YNiC Beamformer Training Session

by Mark Hymers on behalf of YNiC

Hi all, YNiC are pleased to announce our first formal all-day training session. This will take place on Friday 29th September at YNiC and the subject will be MEG Analysis using Beamforming. This will coincide with our general release of the YNiC Beamforming tools which some users have been beta-testing in the past few weeks. The timetable is as follows: ============================================================================= 0900-0915 Coffee and brief welcome talk 0915-1000 Talk: Introduction to Beamforming 1000-1030 Demo: How to use Beamforming at YNiC (Demonstration data) 1030-1045 Coffee break 1045-1130 Workshop: Using the Beamformer 1130-1215 Talk: Common pitfalls in MEG data analysis 1215-1300 LUNCH: (Sandwich buffet will be provided) 1300-1345 Talk and discussion: Review of results on test data 1345-1430 Talk: Why is nothing working? How to troubleshoot 1430-1445 Coffee break 1445-1530 Talk: Virtual electrodes 1530-1630 Workshop: Using virtual electrodes and examining your own data ============================================================================= To make sure that people get the most out of this training session, there will be a limit of 25 participants. Due to this training session, the YNiC Open Plan will be closed all day on the 29th to those not attending the training session. MEG will be undergoing planned maintenance that day and so will also be closed (a further announcement about this will follow soon). As this is the first YNiC training session, we will be providing lunch for the course attendees to celebrate the first of what we hope will be many such courses. To register for this course please email training(a)ynic.york.ac.uk with your name and email address. Registration will close when we have 25 people or on Friday 22nd September (although we expect places to fill up quickly). Finally, we will soon be running a poll on the YNiC website to find out the best times to run future training courses. Again, we will make an announcement about this soon. Thanks, Mark (On behalf of everyone at YNiC) -- Mark Hymers York Neuroimaging Centre

Structural Scans

by a.morland＠psychology.york.ac.uk

Dear All, Thanks to some work from Andre, it has now been determined that the current structurals are fit for purpose. Although the scalp identification is a little noisy, the fits to the scalp information derived in MEG do not appear to be unduly compromised. So, structural scans can be acquired for the use with MEG data. Although Andre has checked the registration of the MRI and MEG scalp information on a few data sets, it really would be helpful if all users who acquire such data could visually inspect their registrations (the docwiki has information on how this can be done). Please alert us to any discrepant registrations and proceed with caution. Sorry for the rapid turn around on this issue. I am loath to recommend scanning when the images are clearly not of the quality that we have previously obtained, but in this case I think we can proceed (with caution). The change in the image quality will still be pursued with GE. Happy scanning! Tony

MRI Operational and Structural MRI

by a.morland＠psychology.york.ac.uk

Dear All, As some of you may be aware, the recent MRI upgrade has introduced an undesirable effect on the acquisition of structural anatomy scans, which are routinely used in MEG analysis. The problem is subtle, but the code that automatically identifies the skull runs less smoothly on the recently acquired data. GE have been informed. As of now, structured MRIs for the use with MEG will not be acquired, unless there are some exceptional circumstances. MEG data can be acquired, but participants will have to be rescheduled for their structural MRIs. Please note however, that self-contained MRI studies will not be affected in the same way because they are not so critically dependent on identification of the skull surface. Thus, acquisition of functional data and structurals (for registration) can proceed. On a more positive note, the MRI scanner is up and running today. Tony

Shape/texture experiment - participants wanted

by Cristiana Pratesi

Researchers at the University of Durham are seeking healthy volunteers to participate in neuroimaging experiments using functional magnetic resonance imaging. The experiments will be performed at the York Neuroimaging Center using a 3Tesla magnet. We will start a new experiment in the next couple of weeks and participants will be asked to discriminate visual objects on the basis of their geometrical (shape) or surface (texture) features. Visual stimuli are images of 3D objects, and behavioural responses will be collected via button press. Typical sessions last for 1-2 hours, and involve lying still in the scanner while brain images are recorded. For detailed information about the experiment see attached file. The experiment is part of a research project based at the University of Durham. The experimenter is Dr. Cristiana Cavina-Pratesi and the main investigators are Prof. D. Milner; Prof. C. Heywood and Prof. R. Kentridge. If you are interested, read the information below and if you think to be eligible for participating, please fell free to contact Dr. Cristiana Cavina-Pratesi cristiana.cavina-pratesi(a)durham.ac.uk for further information. Your name will be entered in a database. You can decide to remove your name from the database at any time and you are always free to decline when an experimenter contacts you. To be eligible to participate, you must: a.. have no metal in your body (fillings are okay) b.. not be claustrophobic c.. be able to remain relatively still for periods of 5-8 minutes d.. be in good health and have no history of neurological disorders (e.g., epileptic seizures, head injuries) e.. be able to see without glasses (contacts are okay) at arms' length (for vision experiments); Thanks in advance for your attention Cristiana Cavina-Pratesi

Image of the Month

by Michael Simpson

Dear all, As of this email, the YNiC Image of the Month competition is live. Let me explain ... Each month YNiC is encouraging Users to submit an image of general interest, plus up to 100 words of explanatory text, into the Image of the Month contest. The best image will then be put on the web and published along with its text for a month. So, do you fancy seeing your work held up as an example of the science that is being carried out at YNiC? If so, email your images and text to: iotm(a)ynic.york.ac.uk Please send your images in .jpg (or similar format) to keep the file size small. Images will be judged by YNiC staff for both their aesthetic and scientific content. So, make your pictures pretty, but also make sure they explain something of the hypothesis which you are testing. Your 100 words will be essential in swinging this part of the vote! Good luck, Michael -- Dr Michael Simpson Science Liaison Officer York Neuroimaging Centre Innovation Way York YO10 5DG Tel: 01904 567614 Web: http://www.ynic.york.ac.uk
