COMP Methods Lunch

Methods lunch is a biweekly lunch meeting for interested PIs, Postdocs, PhD and MSc students. The meeting provides a platform for:

  1. Neuroscientists who would like to discuss and receive input for the design and analysis of their behavioural, neuroimaging or neurophysiological experiment.

  2. Computational scientists presenting new methods to see if they can be useful to the neuroscience community.

  3. Discussing new method papers in Computational Neuroscience / Computational brain imaging.

Meetings are scheduled on Mondays 12:30-2:00 pm in WIRB 4190 (lunch room)Bring your own lunch!
