PhD student position in the NCC lab at the European Neuroscience Institute Göttingen, Germany
by Caspar M. Schwiedrzik 12 Dec '21

12 Dec '21

External Email - Use Caution The NCC Lab at ENI Göttingen is looking for an outstanding *PhD student (f/m/d)* Specialization: interested in studying face perception and predictive processing in non-human primates Limitation: Appointment until 31.12.2025 Working period: 65 % (25,025h/week) Tariff: Entgelt nach TV-L Announcement published on 10.12.2021 Vacancy from 12.08.2021 Application deadline: 14.01.2022 At the University of Göttingen, a new Collaborative Research Center (CRC) 1528 “Cognition of Interaction” will be established with funding from the German Research Foundation (DFG). In 22 projects, the CRC 1528 “Cognition of Interaction” investigates how fundamental cognitive functions and their neurobiological foundations contribute to human and nonhuman primate social behavior and social interactions. The CRC is formed by a highly interdisciplinary consortium formed by systems and computational neuroscientists, data scientists, psychologists and behavioral and cognitive biologists. Partner institutions are the University of Göttingen, the University Medical Center, the German Primate Center, the Max Planck Institute for Dynamics and Self-Organization, the University Hospital Hamburg-Eppendorf and the Weizmann Institute of Science. In the context of this CRC, the Neural Circuits and Cognition Lab of Caspar Schwiedrzik at the European Neuroscience Institute Göttingen is looking for an outstanding PhD student interested in studying face perception and predictive processing. The project investigates neural mechanisms of face perception and predictive processing at the level of circuits and single cells, utilizing functional magnetic resonance imaging (fMRI) in combination with electrophysiology and pharmacology in non-human primates. The Neural Circuits and Cognition Lab seeks to understand the cortical basis and computational principles of visual perception and experience-dependent plasticity in the macaque and human brain. To this end, we use a multimodal approach including fMRI-guided electrophysiological recordings in non-human primates and fMRI and iEEG in humans. The PhD student will play a key role in our research efforts in this area. The lab is located at the European Neuroscience Institute Göttingen (https://secure-web.cisco.com/1M4ih3bIajicoiya9v-lqOnKTS2CbqlGDKae_4HyuGj9V4…) and the German Primate Center ( https://secure-web.cisco.com/1e7PDNnx3vJ0Ki_w3J2EmcwNhCg10VhPvan20Jo38LbRUq…) which are interdisciplinary research centers with international faculty and students pursuing cutting-edge research in neuroscience. Further scientific exchange within the CRC and the Leibniz ScienceCampus ‘Primate Cognition’ (https://secure-web.cisco.com/1UjuTZ8yx1wgmVQdVS8O0yc_fODUaQGXoFT7_Mfln9abC9…) ensures a broad interdisciplinary framework for networking and cooperation. The PhD student will have access to a dedicated imaging center with a dedicated 3T research scanner, state-of-the-art electrophysiology, and behavioral setups. For an overview of our work and representative publications, please see our website https://secure-web.cisco.com/1gqoIp_WsMnNp-n-3I7LUzUkns35bMM3Vw8vYQBUosgdje… The position is funded until 31.12.2025. The successful candidate will join one of the many excellent graduate schools on the Göttingen Campus.Candidates should have a degree (master, diploma or equivalent) in a relevant field (e.g., neuroscience, psychology, biology), and ideally prior experience with non-human primates, strong quantitative, programming, and experimental skills, and share a passion for understanding the neural basis of visual perception and its plasticity. A good command of English is a requirement, but fluency in German is not essential. Interested candidates should send their curriculum vitae, a description of their scientific interests and the names and contact information of two references who are able to comment on your academic background and who agreed to be contacted to Caspar M. Schwiedrzik (cschwie3(a)gwdg.de) The University Medical Center Göttingen is committed to professional equality. We therefore seek to increase the proportion of under-represented genders. Applicants with disabilities and equal qualifications will be given preferential treatment. We look forward to receiving your application by 14.01.2022: University Medical Center Göttingen European Neuroscience Institute Göttingen Dr. Caspar Schwiedrzik Group Leader Grisebachstr. 5 37077 Göttingen Tel.: +49 0551/39-61371 E-Mail: cschwie3(a)gwdg.de Web: http://secure-web.cisco.com/1-7988TeJhnzxuk_F1uUcu7-YL8le_tn5NmaUJxD5RVg9Ta… Contact person: For questions about the position or project, please contact Caspar M.

Freesurfer recon-all error “mri_convert: extra argument”
by William McCuddy AZ-Phoenix 11 Dec '21

11 Dec '21

External Email - Use Caution Hello Freesurfer Community, I'm new to freesurfer and could use some help with recon-all on a single subject. The input file is a 3D T1 WAND from a Philips scanner. I used dcm2niix to convert from dicom to nifti. I can open the nifti file and everything looks normal. nNfti header info displayed in screenshot below and computer specs are listed in the attached recon-all log file (shortened). Not sure what the “mri_convert: extra argument” problem is. If anyone knows what I’m doing wrong, I would love some assistance!

White matter

Hi FreeSurfer experts, I know that FreeSurfer genrates WM information (area/volume) for smaller cortical regions (e.g, superiortemporal, supramarginal) along with the GM information. But, I was wondering is there a way to generate larger WM structures (e.g., temporal lobe or parietal lobe) using freesurfer? Thank you, Rahul

question about surface registration to an average surface
by Trisanna Sprung-Much 10 Dec '21

10 Dec '21

External Email - Use Caution Hi there I have a bunch of labels on individual subjects and would like to register them to an average surface that we have created here at the MNI. So, this average has not gone through recon-all and there are no freesurfer recon-all files associated with it. There is no volume associated with it to run in recon-all. According to the instructions for mri_surf2surf I need the sphere.reg file, which is generated during recon-all. I wonder if there is a way to undergo surface registration in my situation? I found the following documentation, but this seems to be for creating a new average. I have the average already. https://secure-web.cisco.com/1hQ9hS6yFMKayjbN2TstCM6s3-2VxHitXzaDRkJ6eA1mJJ… SurfaceRegAndTemplates - Free Surfer Wiki<https://secure-web.cisco.com/1hQ9hS6yFMKayjbN2TstCM6s3-2VxHitXzaDRkJ6eA1mJJ…> The output from registration is yet another version of the subject's surface mesh, typically named ?h.sphere.reg, with the x,y,z vertex positions still on a sphere, but warped so that the subject's curvature pattern best aligns with the template data.Here is the same convexity data, now plotted on the lh.sphere.reg surface. Similar pattern, but "stretched around". surfer.nmr.mgh.harvard.edu Thank you, Trisanna -- Trisanna Sprung-Much, PhD Research Associate McGill University Montreal Neurological Institute

Questions about GLM
by Laura Willers de Souza 10 Dec '21

10 Dec '21

External Email - Use Caution Hello FreeSurfer Developers, I would like to assess whether my regression model meets the GLM assumptions, especially if there is no multicollinearity. Is it possible to perform this diagnosis in freesurfer? If not, is there a way to extract the model residues to test in another program? Or, is there any way to perform a regression with correlated variables in freesurfer? Thanks in advance!

The data look pretty noisy in those images. My guess is that the WM is not getting segmented properly in that temporal area or there is an incorrectly fixed topology error. Try looking at the wm.mgz (or the filled.mgz instead if you have 7.2). YOu can load surface.defects.mgz to see where the defects are.

howto create a .label files with dilated content
by Krieger, Donald N. 10 Dec '21

10 Dec '21

External Email - Use Caution I wish to use the "-dilate n" capability of mri_extract_label or other tool to create label files for ctx regions. mri_extract_label appears to only be capable of writing output to .mgz files and I do not find a tool for extracting labels from a .mgz into an ascii .label file. Your direction would be welcome. Thanks - Don [cid:image001.jpg@01D7E53E.59F4AFA0] Don Krieger, Ph.D. Research Scientist Department of Neurological Surgery University of Pittsburgh
