Especially for neuroscientists, I would recommend Izhikevich's book, which you can find in its entirety here. If you're keen on MATLAB, check out Stephen Lynch's book on the subject. This is especially good for an intuitive introduction.
In my opinion, the best high-level book on general dynamical systems is Guckenheimer and Holmes, though you may save this one for later.
EDIT: For a good "peek" into the computational neuroscientist's toolbox, I highly recommend ModelDB, a large online database of neural models. For example, I searched "attractor + matlab" on this database and got these links, some of which may interest you.
