layer-fMRI Webinar MBIC 2020

Title: High resolution fMRI: An introductory course for data acquisition and analysis challenges.

Support: This lecture series is finanzially supported by the FPN-MBIC-school. The session on sequences and sequence artifacts is supported (in kind) by the York-Maastricht-partnership grant. Faruk Omer Gulban works for Brain Innovation.

Coordinators: Laurentius (Renzo) Huber & Omer Faruk Gulban, Cognitive Neuroscience Department

Email: renzohuber@gmail.com or faruk.gulban@maastrichtuniversity.nl

Dates: 7, 14, 21, 28 July 2020 (4 sessions in total), 3pm to 4:30pm.

Video Conference Zoom link (note that these sessions may be recorded): https://maastrichtuniversity.zoom.us/meeting/register/tJAvcu-qpj8sHNVD71Vcu95et-R14QKRs22T

Objective(s):
This course will be an introduction to acquiring and analyzing high resolution (<1mm) functional magnetic resonance imaging (fMRI) data. The course participants will acquire data and analyze with the guidance of the course coordinators.

After this course, participants will be able to:

  • Give a rough overview of the seminal papers, challenges and prospects of laminar fMRI
  • Discuss the most common artifacts at the scanner and how to address them
  • Make more informed decisions for their own high resolution fMRI acquisitions.
  • Use image registration and segmentation methods to address some of the most challenging analysis steps.

Literature: There will be no textbook. Individual articles will be suggested for the sessions 3 and 4.

Form of assessment: Attendance (all 4 sessions).
