External Email - Use Caution Hi Freesurfer Community Support Team: We would like to use FreeSurfer QA tools. After installing it, I tested it on one subject that finished Freesurfer recon-all processing using the latest FreeSurfer 7.1. but got errors that seem many files are missing in the mri, surf, stat folders created by FreeSurfer. I attach the recon_checker summary log and zipped snaps file for your reference. Looking forward to hearing from you. Thank you very much. Best regards Xin

12 Aug '21

External Email - Use Caution The Motor Neuroscience and Neuroimaging Laboratory in the Department of Kinesiology and Applied Physiology at the University of Delaware (https://secure-web.cisco.com/1XTz2R8VijcqZlx4YSp9AX3X5lMJCsbG9XVQU91avZ7TSx… <https://secure-web.cisco.com/1XTz2R8VijcqZlx4YSp9AX3X5lMJCsbG9XVQU91avZ7TSx…>), led by Dr. Roxana Burciu, is seeking motivated and enthusiastic students interested in pursuing a PhD in Neuroscience starting as early as Spring 2022 or Fall 2022. The lab aims to improve our understanding of human neural control of movement and leverage this information to improve motor function, mobility and the quality of life of individuals with movement disorders such as Parkinson’s disease. Students will work in an innovative research program that combines advanced functional and structural brain MRI techniques (task-based and resting state fMRI, arterial spin labelling, diffusion MRI, SWI), behavioral protocols and genetics to understand how the brain and behavior change in people with Parkinson’s disease and those at risk of developing the disease. The lab has access to UD’s Center for Biomedical and Brain Imaging which houses a 3T Siemens Magnetom Prisma whole-body MRI scanner and a 9.4 Bruker Biospec 94/20, designed for pre-clinical MR imaging and MRI research. The lab is also integrated with several other research laboratories studying the neural control of movement in healthy and Parkinson’s disease, which provides a rich scientific and collaborative community. PhD positions are funded through a combination of teaching and research assistantships. Requirements: Have a background in neuroscience, biomedical engineering, kinesiology, psychology, or biomedical sciences. Previous MRI experience is desirable. Have some experience with signal processing, bash, MATLAB or similar programming languages. Be team-minded, flexible with the required tact and sensitivity for working with patients with neurological disorders. Potential applicants should contact Dr. Roxana Burciu at rgburciu(a)udel.edu <mailto:rgburciu@udel.edu> with a brief email expressing their research interests, and a current CV. -- Roxana G.
