Recently on twitter I asked for advice on computational modelling and/or computational neuroscience courses, in particular summer schools for early career researchers. I received quite a few suggestions so thought I would create a list for anyone else who is interested. Note, I only know about these courses through recommendations and/or the information on their website. For some, the link is for a previous years course, so I can't guarantee they are definitely still running. Still, I hope the list proves useful for some.
Computational modelling of cognition with applications to society
Advanced course in computational neuroscience
Computational psychiatry course (Zurich)
Computational psychiatry course (London)
Summer school in computational sensory-motor neuroscience (CoSMo)
Model-based neuroscience summer school
OIST computational neuroscience course
Brains, minds and machines
Computational neuroscience and the hybrid brain
ACT-R spring school and master class
If anyone else has further suggestions, I'm happy to continue to update this list. Just leave a comment with the link and name of the course.
