Equipment in ynic

by Gary Green

Please can I make something very clear. No equipment should be taken from meg or mri under any circumstances. To do so puts other peoples' projects at risk and could also affect calibration issues. If people need to use equipment such as that housed in meg or mri, then they should discuss their needs directly with the user support manager, Andre Gouws, or myself. But to repeat myself , I will not give permission for any equipment to be removed Gary Green

YNiC seminar today

by rem

This afternoon David Crewther will give a project proposal talk at 4 pm in YNiC open plan entitled "Nonlinearities in Multi-focal Magnetoencephalography" Abstract Multi-focal visual evoked potentials have become a standard tool in the diagnosis of glaucoma and retinal vascular disease. However, the randomization techniques employed to de-correlate sequences for stimulation of patches of visual field also offer the opportunity for analysis of non-linearities in evoked responses. These have been used to derive separate magnocellular and parvocellular contributions to the cortical VEP. Here we propose to develop similar m-sequence based pseudo-random stimulation techniques to MEG with the purpose of localizing the time-course of activation of the M and P pathways as they extend into dorsal and ventral cortical streams. A beam-former approach to this question will be followed, answering questions regarding the role of the “magnocellular advantage” in object recognition. An initial 13 patch cortically scaled m-sequence multi-focal stimulus has been developed. Extensions to higher resolution cortical imaging are proposed. However multi-focal fMRI imaging indicates eye-movement control is vital. Hence a gaze-contingent system using retinally-stabilized presentation is being developed that will allow an estimate of the optimal high resolution MEG mapping of visual cortex. All welcome *YNIC 5th Birthday drinks will be held immediately after the seminar* -- ************************************************************************ Dr. Rebecca E.

YNiC IT systems at-risk period

by Mark Hymers

Hi, On Thursday 3rd June between 1000 and 1500, we will be having the YNiC Server Room UPS serviced. This means that there will be no backup power in the server room during this time. This should not cause any disruption except in the unlikely event of total power loss to the Biocentre during this time. Unfortunately this work is unavoidable and it is not practical to have it performed out of hours. In the event of a major failure during this time, we have plans to shut down the cluster and use auxiliary UPSes to bring core systems back online quickly. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

Small software update

by Mark Hymers

Hi, I've just pushed a patched fslview out to all of the YNiC machines (including remote desktop service). The only change in this version is that it now defaults[0] to saving masks which are created as .nii.gz (NIFTI files) instead of .hdr/.img pairs (ANALYZE format). This makes sense as the rest of FSL has deprecated ANALYZE support and it causes all sorts of trouble later on in the analysis stream. Thanks to Jodie for bringing this to my attention. Please let me know of any problems this causes or if you find any machines which didn't get the update. Cheers, Mark [0] Although I say "defaults to", you can't force a different file output type easily in the GUI as far as I can tell. If anyone needs to for some reason, the correct way to make fslview output ANALYZE is to run fslview from the command line having first set the FSLOUTPUTTYPE environment variable, i.e.: $ export FSLOUTPUTTYPE=ANALYZE $ fslview I've no idea why anyone would want to still be using ANALYZE, but thought it should be mentioned for the sake of completeness. This is also the same mechanism as applies for the rest of FSL, but it should be noted that ANALYZE support is now partial and I believe is slated for removal in a future release. -- Mark Hymers York Neuroimaging Centre

If your fMRI protocol (usually set up be me and saved for you one the scanner) uses BrainWave during acquisition (the screen that pops up after the radiographer does the prep-scan before each fMRI acquisition), please note the following: An observed bug in the GE software means that slices may be lost of if the BrainWave window is closed prematurely. If you are using Brainwave (i.e. if it is visible during your acquisitions) please make sure that it has reached 100% in the bottom right corner before closing it and moving on to the next scan .. either check this yourself or ask your friendly radiographer to check this for you on every scan.

Seminar today

by Gary Green

Vitaly Napadow "Neuroimaging in basic and translational acupuncture research" This talk will take place today from 12-1 pm. Link to Vitaly Nadapow's website: Vitaly Napadow's webpage: http://www.nmr.mgh.harvard.edu/~vitaly/ *Brief Bio* Dr. Vitaly Napadow is an assistant professor at Harvard Medical School and the Department of Radiology at Massachusetts General Hospital. He received his Ph.D. in biomedical engineering from the Massachusetts Institute of Technology. Vitaly also graduated from the New England School of Acupuncture (NESA), and practices acupuncture at Brigham & Women's Hospital Pain Management Center. His research interests focus on the processing of acupuncture by the brain, and the mechanisms underlying acupuncture efficacy for various disease states including chronic pain. **Abstract** Acupuncture is an ancient East Asian healing modality that has been in use for more than 2000 years. Unfortunately, its mechanisms of action are not well understood, and controversy regarding its clinical efficacy remains. Importantly, acupuncture needling often evokes complex somatosensory sensations and may modulate the cognitive/affective perception of pain, suggesting that many effects are supported by the brain’s control of central nervous system networks. Modern neuroimaging techniques such as functional magnetic resonance imaging provide a means to safely monitor brain activity in humans and may be used to both characterize brain response to acupuncture stimulation, as well as to map the neurophysiological correlates of acupuncture’s effects on various pathologies. In this talk, I will outline some of our lab’s recent studies including (1) mapping the specific brain correlates of acupuncture sensation, known as deqi, which is thought to be associated with good clinical outcomes, (2) investigating acupuncture’s delayed effects on resting functional connectivity in default mode and sensorimotor brain networks, and (3) evaluating the effects of a course of clinical acupuncture therapy on somatosensory processing and somatotopy in patients with carpal tunnel syndrome.

Today in YNiC

by Gary Green

This afternoon, the CEO of the MRC will be visiting YNiC. He will be in MRI and then MEG from 2.20pm until 3pm. If you would like to present an aspect of your work, even for 10minutes, you would be welcome to come along. There is also a seminar today at 4pm This week Gina Humphries will give a project proposal talk at 4 pm in YNiC open plan on "Semantic indeterminacy in the brain: linking production and comprehension processes". Abstract: "This study aims to examine which regions of the brain are recruited during sentence comprehension and sentence production. Gennari and MacDonald (2008, 2009) have recently argued that semantic ambiguity as to who-is-doing-what-to-whom in phrases is an important source of reading difficulty. For example, in reading “the movie that the director…,” a similar interpretation is entertained 90% of the time (that the director wrote the movie), whereas in reading “the director that the movie….,” many interpretations are possible. The authors showed that the proportion of alternative relationships entertained between the nouns, as indexed by a sentence completion study, predicts reading difficulty. Here, we aim to investigate the brain mechanisms underlying the comprehension and production of these structures. Specifically, we ask whether left inferior frontal gyrus (LIFG) and other regions of the language processing network such as posterior middle temporal gyrus (PMTG) are sensitive to the degree of who-is-doing-what-to-whom ambiguity in comprehension and production."

YNiC seminar 13th May

by rem

Dear Users This week Azizah Almaghyuli will give a project proposal talk at 4 pm in YNiC open plan on "Naming and comprehension after transcranial direct current stimulation in health volunteers and patients with stroke aphasia". The study will evaluate the effect of transcranial direct current stimulation( tDCS) on picture naming and synonym judgement in healthy participants, with the ultimate aim of evaluating whether this technique could be used to improve naming and comprehension difficulties following a stroke. Everyone is welcome to attend. Best wishes Rebecca -- ************************************************************************ Dr. Rebecca E.

external speaker at YNiC on 24th May

by rem

Dear Users Vitaly Napadow from the Department of Radiology, Harvard Medical School, will be giving a talk on "Neuroimaging in basic and translational acupuncture research" on Monday 24th May. This talk will take place from 12-1 pm in YNiC open plan. Everyone is welcome to attend. Best wishes Rebecca Link to Vitaly Nadapow's website: http://www.nmr.mgh.harvard.edu/~vitaly/ <http://www.nmr.mgh.harvard.edu/%7Evitaly/> *Brief Bio* Dr. Vitaly Napadow is an assistant professor at Harvard Medical School and the Department of Radiology at Massachusetts General Hospital. He received his Ph.D. in biomedical engineering from the Massachusetts Institute of Technology. Vitaly also graduated from the New England School of Acupuncture (NESA), and practices acupuncture at Brigham & Women's Hospital Pain Management Center. His research interests focus on the processing of acupuncture by the brain, and the mechanisms underlying acupuncture efficacy for various disease states including chronic pain. **Abstract** Acupuncture is an ancient East Asian healing modality that has been in use for more than 2000 years. Unfortunately, its mechanisms of action are not well understood, and controversy regarding its clinical efficacy remains. Importantly, acupuncture needling often evokes complex somatosensory sensations and may modulate the cognitive/affective perception of pain, suggesting that many effects are supported by the brain’s control of central nervous system networks. Modern neuroimaging techniques such as functional magnetic resonance imaging provide a means to safely monitor brain activity in humans and may be used to both characterize brain response to acupuncture stimulation, as well as to map the neurophysiological correlates of acupuncture’s effects on various pathologies. In this talk, I will outline some of our lab’s recent studies including (1) mapping the specific brain correlates of acupuncture sensation, known as deqi, which is thought to be associated with good clinical outcomes, (2) investigating acupuncture’s delayed effects on resting functional connectivity in default mode and sensorimotor brain networks, and (3) evaluating the effects of a course of clinical acupuncture therapy on somatosensory processing and somatotopy in patients with carpal tunnel syndrome. -- ************************************************************************ Dr. Rebecca E.

FSL 4.1 upgrade

by Mark Hymers

Hi, I intend to upgrade FSL 4.1 on the YNiC Systems over the weekend from the current version (4.1.4) to the latest release 4.1.5.2. Details of the changes (which are only minor) are available at: http://www.fmrib.ox.ac.uk/fsl/fsl/whatsnew.html#revisions The only thing which is really relevant is that FLAMEO has a fix in it (which is strangely listed in the 4.1.4 errata, but seems to have only been released in 4.1.5) In addition, I've merged two extra bug fixes, one in fslmaths (related to TFCE calculation) and a syntax error fix in one of the scripts. Details are below as a patch series.
