4D Neuroimaging
by Gary Green 17 Feb '09

17 Feb '09

Dear fellow MEG users It with great sadness that I heard yesterday of the demise of 4D Neuroimaging corporation. 4D had been producing MEG equipment for 25 years and had been the most stable of the manufacturers. Unfortunately the financial situation has hit their funders very hard and they are no longer able to provide funds such that 4D can continue trading. There is an attempt to set up a service division as most of the parts that comprise a MEG machine are made by third parties. Unfortunately there is no guarantee that this can be achieved. We are carefully considering all of the options and contingencies that will be necessary to keep MEG here in York. I will endeavour to keep you informed of our progress in doing so. At the moment the equipment is working well and research and clinical studies are continuing as normal. Please do not be put off carrying out an MEG study (yet). Our thoughts should be with the staff at 4D. All have been laid off without last months salary, no redundancy or pension. They have been good to us and I am sorry that the relationship will come to an end Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG http://www.ynic.york.ac.uk tel. 01904 435349 fax 01904 435356 mobile 07986 778954

The power cut
by Gary Green 12 Feb '09

12 Feb '09

You will be pleased to hear that all systems are working here at YNiC following the power cut yesterday. There was slight delay in getting the scanner back on this morning because I couldn't find the fuse! I would like to publicly thank Mark Hymers for the sterling work he did last night in bringing all the systems back on-line so quickly and efficiently. The power cut was a good test of all our systems here and, it seems, that we have not lost any data or emails. Of course cluster jobs will need to restarted.

Today at YNiC
by Gary Green 12 Feb '09

12 Feb '09

We have an interesting day in YNiC. The Chancellor of the University is visiting at 2pm and then at 4pm we have the poject presentations by the Masters students. Do come along to both. The Chancellor has asked to meet users and I am sure that you will be keen to hear about the new exciting plans for projects this year on the Masters course. Here is a list of working titles and the students who will be presenting each talk: Does language modulate activity in motion perception area V5? Caroline Jennings Gina Humphries Katherine Newling Yiwen Tan The neural basis of familiar face recognition from fMR adaptation Ajay Hallai Nick Arthur Emma Pagett Investigating semantic cognition (TMS) Jamie O'Sullivan Marie Kirk Investigating semantic cognition (Neuropsychology) Jen Wathan This session will take start at 4 pm in YNiC. The talks may run on past 5 pm, depending on the duration of the talks and questions. Everyone is welcome to attend. -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG http://www.ynic.york.ac.uk tel. 01904 435349 fax 01904 435356 mobile 07986 778954

Power outage
by Mark Hymers 11 Feb '09

11 Feb '09

Hi, This evening there was a major power outage affecting YNiC. The Science Park and parts of the University were affected. Most systems were taken down in a co-ordinated manner during the period which the UPSes provided power and we believe that most user-visible systems are now up and running again. It is possible, however, that some areas have been overlooked or that there may be lingering problems. Please let the DSO know if this is the case and they will bring it to the attention of the right staff to deal with it. Any cluster jobs running at the time of the outage will be cleared and will need to be re-run. Please note that we do not intend to bring the cluster up again until tomorrow morning at the earliest and there may be some delay in getting the whole cluster running again. Sorry for the inconvenience. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

[Fwd: This week's seminar at YNiC]
by Gary Green 05 Feb '09

05 Feb '09

In one hours time do come ------------------------------------ Dear colleagues This week we will discuss the design of a set of MEG and fMRI experiments that could be used to form the basis of a 'gold-standard' dataset that could be used to compare and contrast current MEG analysis techniques as well allow the testing of future analysis algorithms. Andy Young has proposed that we start this exercise by collecting data that would primarily activate sensory cortices as one should be able to predict the outcome. The aim would be to collect data in as 'perfect' a manner as possible and would include the recording of eye movements, EOG and ECG signals. The specific design of the experiments will be discussed this Thursday at 4pm. We will also discuss how we will use a suite of analysis tools to examine different source localisation and reconstruction methods. Examples of how this could be achieved will be presented by members of the YNiC team but the idea is that an analysis task-force would be encouraged to tackle the data. One of the aims is to use this data to refine our data analysis and statistical methods. We hope this will lead to clear guidelines as to the 'best' way to approach MEG experimentation and source analysis. The outcomes will determine how we develop the analysis software framework and will, hopefully, result in even clearer documentation for users as well as publications. Do come and contribute. All welcome Gary -- Gary Green York Neuroimaging Centre The Biocentre York Science Park Innovation Way Heslington York YO10 5DG
