Today in YNiC
by Gary Green 20 May '10

20 May '10

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." 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 https://www.ynic.york.ac.uk/about-us/people/ggrg tel. +44 (0) 1904 435349 PA (Claire Fox) +44 (0) 1904 435329 fax +44 (0) 1904 435356 mobile +44 (0) 788 191 3004

Dear Users Today 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.

The programmer will be responsible for implementing software for all phases of the analysis of magnetoencephalograpy (MEG) and electroencephalography (EEG) data and its integration of other functional and structural imaging modalities. The resulting software, which will be developed under grant support from the National Institutes of Health, will be distributed to researchers throughout the US and the rest of the world, for analysis of data collected in cognitive neuroscience and clinical research studies. This project will be conducted under the supervision of Professor Richard Leahy in the Department of Electrical Engineering and will involve close collaboration with researchers at USC and other institutions. Responsibilities * Play a leading role in developing common workflow, data structures, and file formats for use in analysis of MEG and EEG data. * Develop and document code to implement algorithms for analysis and display of M/EEG data. * Development of procedures for automated testing of software and software updates. * Develop and support procedures for distribution and documentation of new software. * Participate in training of users * Participate in research meetings and interact with PhD students, postdocs and research faculty in Dr. Leahy's lab in the development of new approaches to the analysis of MEG and EEG data. * Work with collaborators who are also developing software to facilitate interoperability between software packages with the ultimate goal of producing a single software package for EEG and MEG data analysis. * More information about Brainstorm, the existing software package: http://neuroimage.usc.edu/brainstorm Minimum qualifications * Masters Degree in Computer Science or Electrical Engineering * 2 years post graduate experience * Knowledge of the basic principles underlying EEG and MEG signal processing * Programming experience with Matlab and Java Conditions of employment * Starting from January 2011 * Duration: position available for a minimum of two years * Salary: depends on experience and qualifications * USC has excellent benefits, including health benefits and retirement plans with employer contributions after six months. * The University of Southern California values diversity and is committed to equal opportunity in employment.

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 06 May '10

06 May '10

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.
