Should you want to contribute anything to the agenda, please email Quentin in advance <aqs1(a)york.ac.uk>. Otherwise, simply come along and join in the discussion. As before, a short digest of the YNiC ASC will be emailed to ynic-users a few days after the session. Nearer the time, Quentin will forward an agenda (i.e. once it has been established). And as before, the session will take place in Psychology B020, at 4pm.

Thursday Seminar

by Sam Johnson

Hello all, Just a reminder and a little more information about this Thursday's Seminar at YNiC. Mark has prepared an introduction to Unix that I will do my very best to translate into something we mere mortals can understand. This week we'll be covering some of the generic basics, including the permissions problem I know has been an issue of late. There'll also be information on some simple command line tools and the basics of scripting. Next week we'll be looking at YNiC specific information, including some useful hints and tips that will hopefully help to save you time and blood pressure. Thanks, Sam

MEG at YNiC : current status

by Gary Green

Dear colleagues I am sorry to have to announce that MEG is not working. We have had a problem since late last week with the Polhemus system which is needed for co-registration of the data with MRI. We thought we had fixed it over the weekend but it is now clear that we have to have a new unit flown in from San Diego. We will also need to get 4D engineers to attend to fix the problem as it is not simply one of replacing the unit. Unfortunately this means that MEG may be unavailable until the middle of next week. I know this is going to be a major inconvenience as MEG is currently very busy. As soon as it is working again we will let you know and will help you rebook or reorganise your time in MEG. We will almost certainly have to organise block booking so that several participants can be scanned one after the other to get through the backlog. The MEG system itself is working fine! Projects are stalled because of a piece of equipment that costs less than 1% of the original MEG cost.

YNiC ASC session on Virtual Electrode Analyses in MEG

by Andy Ellis

Dear All NOTES ON THE YNIC ANALYSIS SUPPORT COLLOQUIUM ON VIRTUAL ELECTRODE ANALYSES IN MEG, WEDNESDAY 13 FEBRUARY 2008. The current YNiC MEG tools allow us to create beautiful and defensible images showing how the brain's responses to stimuli evolve over time. But beamforming requires the comparison of active windows with passive windows, and the use of active windows less that 200 ms long is not recommended. So while moving windows convey a good initial impression of the progression of neural events, they do not take full advantage of MEG's potential for looking at the detailed timing of those events. There is another issue with beamformed brain maps, which is that it is not easy to compare results across conditions. You can point out that there is a significant response in a particular brain region in one condition of an experiment but not in another, but it could be that the response just makes it over the threshold in one condition and just falls below threshold in the other. The absolute difference in the magnitude of the two responses (or, to be accurate, the magnitude of the difference between the two active and passive conditions) may be small. Virtual electrodes offer the potential for asking intelligent questions about the strength and time course of events at specific points in the brain, allowing direct comparisons between conditions and making better use of the temporal resolution of MEG. Piers Cornelissen presented the results of some virtual electrode analyses he and his colleagues have done, comparing responses to different types of stimuli at different regions of interest in the brain. Piers showed results in the form of time-frequency histograms ('Stockwell plots'), separating out evoked and induced components of the total response; also event-related frequency (ERF) plots showing changes in the amplitude of evoked responses over time. He also discussed techniques that he and his colleagues have used for making statistical comparisons across conditions in both types of analysis. A lengthy and gripping discussion ranged over: 1. The best method to identify regions of interest, 2. How best, having identified a point of interest in a standardised brain, to identify the corresponding points in individual participant brains, and 3. What issues are involved in doing individual and group level analyses, and what would be the best analyses to adopt within YNiC, at least as interim solutions that will allow research groups to make progress with these techniques. Doing virtual electrode analyses at a group level is a complex business but has strong appeal to a number of researchers. Piers has a working solution which he and Uzma will document and make available. In complement to this documentation, YNiC will document the assumptions and issues associated with Virtual Electrode Analysis at the group level. It was also clear in the discussion that connectivity measures applied to Virtual Electrode analysis are going to be important to understanding more about the signals recorded in MEG, and more about how functional interactions involving different regions in the brain evolve over time. Deep thought will be given to this topic within YNiC. Ideas for future fora are welcomed.

Last nights YNiC ASC session.

by Michael Simpson

Dear all, just to say thanks to Andy and Piers for chairing last nights YNiC ASC session; a digest of which will be forwarded to the User list in due course. Given that we gave everyone the option to leave at 5pm, but everyone stayed until 5.30, I'll interpret it to have been and success! It was good that it generated so much discussion. On which note, would anyone like to volunteer to chair the next YNiC ASC session? If so, send an email to the ynic-users stating the topic for discussion, and the date on which you would like to hold the session. I look forward to hearing from you all ... thanks, 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
