Introduction to Computational Neuroscience

Lecture Schedule

The syllabus includes the lecture schedule as well as readings, assignments and dates for quizes. Readings are mandatory and I will assume that you have read them. The appendices contain background material useful for those not experts on certain topics. Notes contain some or most of what I will say in class and are meant to reduce your note taking. For some classes, I will use slides and also post those on the web. Homework and lab modules are due at 6pm on Sunday. Homework will be posted here and on blackboard. Some homework wil be accompanied by a short blackboard multiple choice quiz. There will be five in class quizzes, for each student the quiz with the worst grade will be dropped. There will be a mid-term and final, both are take home. All quizes, homeworks, lab modules, projects and exams are open book, you can use your notes and any information sources you choose. Be aware that this does not mean you should not study!
