IGMN NeuroComputation Workshop

  • Objective: to provide an overview of computational methodologies useful for various types of neuroscience data, plus opportunities to “practice” with example data sets. The “practice” sessions will include basic instruction on using R, python, and matlab; data management, data transfer, and data cleaning concepts; and practice using various data analysis/visualization programs.
  • Dates: presented each year during the summer
  • Schedule: Previous workshop was Aug 6-14, 2018
  • Requirement for Graduate Minor in Neuroscience: Students who attend and engage in all the workshop presentations will receive a “Certificate of Completion”, which will verify that they have met this requirement for the Graduate Minor in Neuroscience.
