Computational Neuroscience

This is a 3rd year Computer Science and MSc unit. We will try to understand how the brain works from a computational point of view.

Coursework

See the coursework folder.

Staff

Important info

All live sessions will be hosted on Microsoft Teams. You should already have been added to the group "COMS30017: Computational Neuroscience (Teaching Unit) 2021/22 (TB-1, A)" You can download the MS Teams app free here, using your UoB email address.

Links

  • Unit forum subreddit: ask questions here. It includes questions from the previous year of the course, so some of the "admin" things may be different. But the course content will be similar!
  • Blackboard page: official University of Bristol landing page.

Overall structure

  • Weeks 1-7: Video lectures for the week released each Monday. Please watch when you can during the week. Each week will cover a different topic. Most weeks will also come with question sheets.
  • Weeks 2-8: Monday 12-1pm, live Q+A session with lecturer(s). Chance to ask questions to the lecturer about the previous week's material. Hosted on Microsoft Teams.
  • Weeks 2-7: Wednesday 11-12am, live bubble discussion seminars. Each bubble will be moderated by a TA or lecturer with discussion topics related to the lecture material. Hosted on Microsoft Teams.
  • Weeks 8-10: Coursework time, for those taking the 20-credit coursework version of the unit (COMS30015).
  • Week 11: Consolidation week. Catch up week for any further lecture material.
  • Week 12: Revision week. Preparation week for those students taking the 10-credit written exam version of unit (COMS30016 or COMSM0039).
