- ynic-users

by Sam Johnson

Hello all, As part of the revamped Thursday afternoon sessions, at 4pm tomorrow there will be project presentations from people planning studies at YNiC. The following Thursday, the 15th, Andre will be demonstrating some of the features of his new visualisation tool. The intention of these sessions is to encourage dialog so that the whole YNiC user community, including YNiC staff, can share the benefits of their experiences and expertise. As such these sessions will take a variety of forms; journal clubs, project presentations, progress reports, seminars, training and so on. In the near future there will be "friendly" requests for investigators involved in projects to prepare informal progress reports, but in the mean time please do come along and partake of some wine and snacks and see what other people are planning. Thanks Sam

MRI data processing

by Mark Hymers

Hi, As some of you will know, due to an interesting issue [0] caused by GE installing an MRI scanner update, we have been having some problems with transferring and processing MRI data recently. Because GE (despite having admitted that this is their fault) are unable to fix this in a timely manner, we've now managed to work around it in house and have processed the backlog of data. Everything up until last week has now been processed and uploaded and last weeks' scans will be processed by the end of today. Apologies for the delay but this came out of nowhere and even diagnosing the problem took quite a bit of time. If anybody thinks that scans they have performed since the start of the year have not been processed, can you please send an email to mri-support(a)ynic.york.ac.uk with details and we'll look into it. Cheers, Mark [0] For Those Who Care About Technical Details The executive summary is that they've changed the two values which represent the Minimum (0028,0108) and Maximum (0028,0109) pixel values in the image from 16 bit signed to 16 bit unsigned. The data which is exported is still 16 bit signed and so this change makes absolutely no sense whatsoever. Quite a bit of DICOM code I've looked at will cope with either US or SS for these values but expects them to be consistent with the actual data (which makes sense, if you're expressing a minimum or maximum, it should be done using the same data type as the data). A full dissection of the problem follows: Old DICOM Image (selected tags only): (0028,0103) US 1 # 2, 1 PixelRepresentation (0028,0106) SS 0 # 2, 1 SmallestImagePixelValue (0028,0107) SS 275 # 2, 1 LargestImagePixelValue New DICOM Image (selected tags only): (0028,0103) US 1 # 2, 1 PixelRepresentation (0028,0106) US 0 # 2, 1 SmallestImagePixelValue (0028,0107) US 2211 # 2, 1 LargestImagePixelValue As you can se from the second column, the two bottom tags have changed their Value Representation from SS (Signed Short) to US (Unsigned Short). I've included the tag (0028,0103) because it explains how the actual pixel data is to be interpreted. MR is fixed at 16 bits which leaves two options: signed (2's complement) and unsigned. To quote from the DICOM Standard: Pixel Representation (0028, 0103): Data representation of the pixel samples. Each sample shall have the same pixel representation. Enumerated values: 0000H = unsigned integer 0001H = 2's complement So, the data is still written as signed, whilst the min and max values are written as unsigned. This is, at least in spirit if not letter, a violation of the DICOM standard. Note that although I state that according to the DICOM spec, MR is fixed at 16 bits, the interpretation of those 16 bits isn't fixed. See the tags BitsStored, BitsAllocated and HighBit if you're interested. (In practice, this is usually fixed for MR at 16, 16 and 15 respectively). The fix is to read the value out of the file and hack the relevant VRs back to being a signed integer instead of an unsigned one. The interesting thing is that images processed with Clariview (e.g. the YNiC Structurals which have FL_E in them) still use the signed value. So not only are GE wrong, they're inconsistently wrong too. -- Mark Hymers York Neuroimaging Centre

Pulvermüller's talk abstract

by Silvia Gennari

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].

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.

This Friday we have a group of visitors attending YNiC some time between 11 and noon. The visit is extremely important for us and the University. When the Open Plan area is busy there is an exciting atmosphere and it would be good to communicate that to the visitors even if they are only present for a few minutes. If you happened to be planning to use the YNiC facilities this week then please consider doing so on Friday morning as it would help us enormously.

MEG benchmarking

by a.morland＠psychology.york.ac.uk

Dear All, I received three responses (please shout if I have ommitted any) to my enquiry concerning projects (past, present and future) that might assist us all in bench testing MEG analysis. The project details are described below and I am hopeful that each of them will inform us on how best to use the MEG tools that have been developed at YNiC. The projects are also at different stages of development and this is likely to allow at least some work to be done in series rather than us spread ourselves too thinly across three parallel projects. I plan to convene some meetings with each project team and YNiC staff to establish how to move forward on each project. These meetings will take the same form as the brain storming sessions that we are now running for project teams. The first of these was run recently and by all accounts was a successful and enjoyable activity. If you could let me know when (usually a Wednesday afternoon from 4pm) you are available to meet, that would be very helpful. Many thanks for responding. Tony Project: P1010 Title: Seeing the neural basis of the left hemisphere advantage for visual word recognition. Investigators: Ellis and Barca.

Structural study

by Tom Hartley

Dear All, I'm pleased to announced that we're about to start a new study which will look at the relationship between the size of the hippocampus and performance on a topographical memory task. The aim is to make use of MRI data collected in connection with previous and ongoing studies. We are looking to make contact with potential participants (healthy adults, aged 18-50) who have already had an MRI scan at YNiC or who will have one over the next 6-9 months. An additional constraint is that they should be available to take part in a brief (15-20 minute) psychological test later in the year. If you have already or are about to conduct a study with suitable participants and are willing to help, we would like to hear from you so that we can begin the process of contacting subjects and identifying studies in which they have participated. We aim to make this as easy for you and the potential participants as possible. There is a also a panel of volunteers who have agreed to be approached regarding future studies at YNiC, and we intend to approach these via the Director. To respond, please use the link below (please be careful not to "reply to all"!): mailto:t.hartley@psychology.york.ac.uk;rch504@york.ac.uk?subject=hvt:I-have- a-study You may yourself have had a scan and be interested in participating - if so, please contact us, and we can then begin the process of tracking down your scan and obtaining permission to analyze the data. There is no need to make a firm commitment at this stage, and as with all such studies, you would be free to withdraw at any time. If this fits you, please use the following link to reply to this message: mailto:t.hartley@psychology.york.ac.uk;rch504@york.ac.uk?subject=hvt:I-have- a-study Further information for potential participants is available at: http://www.neuroindex.org/images/b/bf/HVT_Information_revised.pdf Best wishes, Tom Hartley Rachel Harlow =================================== Dr Tom Hartley Dept. of Psychology t.hartley(a)psychology.york.ac.uk http://www-users.york.ac.uk/~th512 ext 2903

Booking MEG and MRI

by Gary Green

Dear ynic-users It is good to see that many of you are now using the online booking form for MEG and MRI. https://www.ynic.york.ac.uk/user-resources/booking We hope the new procedure is easier than the old method of using email and/or phone. There is a small problem though which we would like to bring to your attention. When you use the online form, you should still wait for confirmation from Claire Fox by email that your session has been booked. This is because several people could, in theory, attempt to book the same hour. Another problem is that some people are attempting to book a session at night for the next day. This is not practical as we need to ensure that an operator is available, that the scanners are available and that all stimulus delivery issues, ethics, and consent are all in place. Please can we ask users to try and book their sessions before the Thursday of the week before they wish to use the scanners. Of course we do not want the scanners to be idle and the resource to be wasted, so, if you want to make a last minute booking and all the practical aspects of scanning are in place, then please ring Claire to discuss the possibility of using the scanners. The key thing then will be availability of operators. -- 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
