Re: [Freesurfer] Beta values (resubmitting)
by Laura Willers de Souza 27 Apr '22

27 Apr '22

External Email - Use Caution Thanks so much! I would also like to confirm that I am interpreting the beta values correctly for a second model. Model 2: Two Groups, One Covariate Contrasts (DOSS): difference between the group intercepts; covariate effect. The fsgd file looks like this: GroupDescriptorFile 1 Title CU_CI_CSF MeasurementName thickness Class CU Class CI Variables cortisolCSF Input 011_S_0003_S9128 CI 2.397895273 Input 022_S_0004_S9233 CI 2.772588722 Input 011_S_0005_S9137 CU 3.044522438 Input 011_S_0008_S9196 CU 2.397895273 Input 011_S_0010_S8800 CI 2.151762203 ... (n=300) The file with the beta values contains 3 lines (image below). [cid:image003.png@01D858C5.3392CD10] * The first line would be the beta value for the intercept of the 1st group; the second line for the intercept of the 2nd group; and the third line for the slope of the covariate? * Thus the glm equation for the 1st cluster would be: * 1st group ---- cortical thickness = 2.64 - 0.12X + n * 2nd group --- cortical thickness = 2.54 – 0.12X + n Am I interpreting correctly? Thank you very much for all the help! Laura Willers de Souza Master Student in Biochemistry Zimmer Lab - Federal University of Rio Grande do Sul - Porto Alegre/RS - Brazil

Opening for PhD position based in Tours (Loire Valley, France)
by briend 27 Apr '22

27 Apr '22

External Email - Use Caution Dear colleagues, The INSERM-U1253 & University of Tours research unit based in Tours (Loire Valley, France) invites applications for a PhD position to begin in the Fall of 2022 on the reward and interoceptive systems in autism. The main objective of the current PhD proposal is to identify impaired social processing in autism and AD across the last two dimensions. To do that, first, this project will explore the neural activity of the reward system in these patients via functional magnetic resonance imaging. Then, we will probe the deficit of interoception present in these disorders. This sensory modality will also be examined in relation to social processes, within an innovative device of immersive reality (the CAVE: computer automatic virtual environments). Applicants should hold a Master's degree (or equivalent) in one of the following disciplines: computational or cognitive neuroscience, computer science, mathematics, physics, cognitive science or related. Prior experience in the field of computational neuroscience and/or neuroimaging are of advantage. Sound knowledge of statistics and programming are essential. The candidate’s main missions will be to program, run and analyze behavioral and neuroimaging tests with individual with autism and healthy controls, involving interoceptive tasks and cognitive tests. A good command of written and spoken English is requested of all applicants. Knowledge of French language is beneficial. Prospective candidates should also contact directly Frederic Briend (frederic.briend(a)univ-tours.fr) and/or Marianne Latinus (marianne.latinus(a)univ-tours.fr) by June 2, 2022. Please include the following documents in your application (as a single PDF-file): Cover letter, curriculum vitae, at least one recommendation letter. The position should start in October 2022.

Postdoctoral studies in Neuroimaging at Karolinska Institute - Last Days to Apply
by Joana Braga Pereira 27 Apr '22

27 Apr '22

External Email - Use Caution Dear all, We are looking for a Postdoc to work in an interdisciplinary and internationally competitive environment at Karolinska Institute, one of the top medical universities in the world and the home for the Nobel Prize in Medicine. We combine imaging analyses, statistical tools, machine learning algorithms, biofluid assays and genetics to study brain aging and the earliest signs of Alzheimer’s and Parkinson’s diseases. This project will be carried out under the supervision of Associate Professor Joana B. Pereira and it will involve analyzing cross-sectional and longitudinal imaging data, combining clinical measures and cerebrospinal fluid biomarkers, as well as writing manuscripts and presenting results in international conferences. The fellow is expected to be independent, develop his or her own projects, supervise students and show an interest in approaches based on graph theory. In addition, he/she will have the opportunity to develop new skills, analyze large datasets, apply for grants and develop a wide network of collaborations. The ideal candidate should have the following qualities: - A PhD in neuroimaging, computational science, neuropsychology, physics, statistics or a related field; - Experience in statistical techniques, programming, or scripting; - Experience with structural MRI, DTI, fMRI or PET imaging analyses; - Clinical or research experience with aging and/or neurodegenerative disorders. - Excellent record of scientific publications. The Postdoctoral studies will be performed for 1 year, with possible extension for an additional year. To apply please go to: https://secure-web.cisco.com/17Z5BFWVOFKkgw67dU4BS_mGuivQTiYdB22cHmKJrEgcp1… (Deadline: 29/04/2022) For further information or general inquires, please contact Joana B.
