NeuroLab is a set of graphical simulations of neural processes at the molecular, cellular or network levels.
I originally designed and wrote the simulations for my Introduction to Neuroscience course. but have since begun using them in other courses as well.
The simulations are written in NetLogo, a software package designed by Uri Wilensky at the Center for Connected Learning (Northwestern University) to explore the behavior of massively parallel systems.
Here is a Zipped Folder containing the Manual and the Simulations currently in NeuroLab:
