by Gary Green 10 May '11

10 May '11

FYI -------------------------------------------------------------------------------------------------------------- The Central Institute of Mental Health in Mannheim, Germany, is an internationally renowned research institute in the field of psychiatry and neuroscience, home of the Department of Psychiatry and Psychotherapy of the Medical Faculty Mannheim of the University of Heidelberg, and a psychiatric hospital with 255 inpatient and 52 day-clinic beds. To strengthen our recently established independent neuroscience research group funded by the Federal Ministry of Education and Research (BMBF), the Clinic for Psychiatry and Psychotherapy (Medical Director: Prof. Dr. med. Andreas Meyer-Lindenberg) offers * * *1 PostDoc and 1 PhD-Student Position* * * in the area of functional and structural magnetic resonance imaging (MRI). Positions are initially limited to 2 years, a prolongation is intended. The Central Institute of Mental Health is equipped, among others, with two Siemens 3 Tesla research MR scanners. Our research group consists of an interdisciplinary team of psychologists, psychiatrists, neurologists, biologists and technical assistants (http://www.zi-mannheim.de/ag_imaging.html). The main goal of the international research project is to examine fronto-striatal plasticity processes and their molecular genetic basis in healthy individuals and psychiatric patients using multimodal magnetic resonance imaging techniques (fMRI, morphometry, DTI, spectroscopy). Ideally, potential applicants will have previous experience with the acquisition, processing and analysis of MRI data, as well as a strong interest in the application of systems neuroscience methods in the context of neuropsychiatric research questions. We offer an interesting job in a pleasant working environment at a leading German research institute. Salary is according to the German TV-L pay scale, including the social benefits of the German public service sector.

[Fwd: [megcommunity] Postdoctoral Fellowship: Multimodal Neuroimaging -MGH/Harvard Medical School]
by Gary Green 13 Apr '11

13 Apr '11

FYI ---------------------- Postdoctoral Fellowship: Multimodal Neuroimaging -MGH/Harvard Medical School Job Description A postdoctoral position is available with the TRANSCEND Research Program (www.transcendresearch.org <http://www.transcendresearch.org/>) at the Martinos Center for Biomedical Imaging in Charlestown, MA (www.martinos.org <http://www.martinos.org/>) which is affiliated with the Massachusetts General Hospital, Harvard Medical School and MIT. We are seeking a candidate with a strong basis in magnetic resonance imaging. Emphasis will be on MRI (DTI, spectroscopy, morphometry, ASL as well as resting state fMRI), and on co-registering MEG with MRI. This position will involve analysis of existing multimodal imaging data and collection of new data. The emphasis of the postdoctoral fellowship will be analysis of existing datasets with secondary activity in piloting data for new studies. It will involve working closely with a multidisciplinary team and with children, and will also involve some research oriented analysis of data collected for clinical purposes. After initial phase-in, ample opportunity will also be provided to the candidate to self-explore and lead research. Datasets to be analyzed include: MRI (including DTI and 1H-spectroscopy) and MEG data on 6-12 and teenage matched autism spectrum and control subjects with phenotyping data MRI data ( (morphometry, DTI, spectroscopy) plus laboratory and phenotyping data) on 70 children with autism plus epilepsy and/or mitochondrial dysfunction, along with one or more overnight EEGs on each patient data from children ages 2-10 with and without autism. Overall objectives: To perform multimodal analyses of research and clinical research data, to develop new approaches for performing these analyses, and to design pipelines for data analysis. To write papers and grants which will be high priorities all along the way and will be actively supported by senior faculty. To take advantage of the world class faculty and facilities of the Martinos Center for Biomedical Imaging to perform the above activities to their maximal potential. The program’s emphasis is on pathophysiologically grounded brain research and application of advanced imaging acquisition and analysis techniques to neurological and sensory aspects of autism spectrum disorders. Requirements: Candidates must have PhD in neuroscience, physics, biomedical engineering, electrical engineering, computer science or other related fields. Prior experience in MRI analysis is required. Experience with EEG will be an added advantage. Salary will be consistent with Massachusetts General Hospital, Harvard Medical School policies for Postdoctoral trainees and will range between $45,000 to $55,000 depending upon qualifications and experience. Compensation also includes full staff benefits, including health insurance, and vacation time. Contact: Interested applicants may send a CV and statement of interest addressing background and specific pertinence of the candidate’s interest to Dr. Martha R. Herbert at mherbert1(a)partners.org <mailto:mherbert1@partners.org> and cc transcend(a)partners.org <mailto:transcend@partners.org>.

Beamforming questions
by Luis Peraza 07 Apr '11

07 Apr '11

More about Beamforming files In a previous mail-list I was told that the *spheres.txt and *transform.txt file are obtained after coregistration of the MEG data to the MRI structural before beamforming. So I imagine that transform.txt matrix takes the NAI voxel values to the MNI space with a 5mm or 2mm volume grid, from the individual/subject brain to the MNI standard. Am I right? Is it MNI standard or the MNI space of the individual structural MRI? But anyway, (and this is a supposition) coregistration should be done first between MEG and the individual MRI structure to perform Beamforming in world/real or physical coordinates (right?). So there should be a previous space transform in world coordinates to perform beamforming, then the NAI values are obtained in world coordinates and finally transformed to MNI space together with the individual structural MRI. Am I right about this? The reason why I am to eager to know this, is because I am doing Beamforming for my project using python-vtk, and so far I have learned how to extract the cortical voxels of individual structrual MRI using BET-FAST from FSL. But in order to run my beamforming I need to transform the structural voxels (in MNI) to world coordinates and also do coregistration between the fiducial skin points, which I imagine were obtained using the stylus pen for 3D modelling during the MEG acquisition with the surface of the subject skin from the MRI. I was wondering if the transform.txt file does the coregistration skin-points-to-skin-surface for the Beamforming, Now I know that it does not. Maybe I will have to program my own coregistration algorithm anyway. I only wanted to know If there were a less painful way to do it. My fifth question is the following. According to the ynic-wiki, it says that I am able to define any voxel in MNI coordinates to define virtual electrodes using the Beamforming functions. The problem is that the wiki does not say how to define this coordinates. From where can I take them? > From the structural MRI or from the MRI standard? Can they be only the cortex or any voxel inside the brain? And my last question is about the sphere.txt file. It is composed of 248 lines, they should be the MEG coils, but I can not imagine the meaning of the rest of the four columns. I was thinking they where x,y,z coordinates, but there is a fourth one that tells me I am wrong. Many thanks, Luis R. Peraza

After doing beamforming there are two files besides the NAI ones, a *spheres.txt and *transform.txt files. My question is which is the purpose of these files. What do they represent? Many thanks. Luis Peraza

MRI help
by Philip Quinlan 26 Mar '11

26 Mar '11

Are there any useful rules of thumb about what the critical cluster size should be in reporting results. I have a results with a cluster size of 1 that reaches the 2.3 threshold. (i) this cant be a real ROI - can it? (ii) why is the critical z val set at 2.3 anyway? Any help gratefully received. Thanks Philip. ******************************************************************** Philip Quinlan E-Mail: ptq1(a)york.ac.uk Department of Psychology FAX: (01904) 323181 The University of York Tel: (01904) 320000 Ext. 3135 Heslington Direct : (01904) 323135 York YO10 5DD U.K. ********************************************************************
