MEG at YNiC : current status
by Gary Green 26 Feb '08

26 Feb '08

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 15 Feb '08

15 Feb '08

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 14 Feb '08

14 Feb '08

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

Virtual electrode analysis in MEG: the 1st YNiC ASC
by Andy Ellis 11 Feb '08

11 Feb '08

Dear All I will attempt to chair a discussion this Wednesday (11th) at 4pm on virtual electrode analysis in MEG. The meeting is the first of the proposed YNiC Analysis Support Colloquia looking at current and future needs for data analysis (MRI as well as MEG). The meeting will take place in the Psychology lecture theatre (B020), NOT in YNiC. Virtual electrode analyses probe individual points in the brain. They potentially allow you to chart the response at that location over time, taking full advantage of the capacity of MEG to record changes over time with millisecond accuracy. Some of us feel, possibly naively, that the ability to do virtual electrode analyses at a group as well as an individual level is all that stands between us and world domination. Piers will begin by demonstrating some group level analyses that he and colleagues have done as part of an MEG study that included written words, consonant strings and faces as stimuli. The aim of the session, however, is not to discuss the meaning of different studies, but what what forms of virtual electrode analysis are possible, and what we could hope to learn from them. If you have attempted any virtual electrode analyses, or think that you may want to do some in future, please bring them along. Anyone who has any results to share is welcome to bring along some slides. So that's Wednesday at 4pm in Psychology B020.

YNiC Analysis Support Colloquia - Wednesday 13th February. B020.
by Michael Simpson 06 Feb '08

06 Feb '08

Dear all, This is just to confirm that Andy Ellis will be chairing the first YNiC Analysis Support Colloquia on Wednesday February 13th. The session will take place in B020 at 4pm. Andy will forward an agenda in due course which will detail the specific questions he will raise in the session. However, following his previous mailing to ynic-users, the general topic of the session will be Virtual Electrode Analysis of MEG data. We look forward to seeing you there. Here's hoping for a good turnout at the inaugural session of what we hope will be a mutually beneficial series of colloquia. 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

MEG Masterclass - Thursday 6th February
by Michael Simpson 06 Feb '08

06 Feb '08

Dear all, this is just a reminder that the MEG masterclass will take place tomorrow. A number of you contacted Andre at the start of the masterclasses to let him know that you are likely to attend these sessions. If you haven't previously let him know of your interest for the MEG class, and would like to attend, please contact *me* so that we can have a rough idea of numbers. The session will take place from 2.30 till 5.00 in Open Plan. 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
