Since 1996, Europe has had annual summer schools in computational neuroscience. It started with the Crete Course in Computational Neuroscience, which subsequently became known as the Advanced Course in Computational Neuroscience (see below). The course has been a largely community-driven effort, and over the years it has become one of the highest-regarded schools of its kind, seeing many of the best computational neuroscientists in Europe and around the world among its directors, faculty, tutors, and students. The most persistent sponsors of the course have been FENS/IBRO and since 2015, with the centralization of their summer schools, the course has been incorporated into their Cajal Advanced Neuroscience Training Programme and has found a new home in Lisbon. The mission of the new Cajal Course in Computational Neuroscience is to continue the tradition of the previous European courses and provide an advanced, comprehensive, and intensive course for a future generation of neuroscientists, be they theoreticians or experimentalists. The school focuses on techniques and approaches of computational neuroscience, which are increasingly recognized as being indispensable to understanding the nervous system.
