XSim:

XSim is a neural network simulator that allows to construct a wide variety of neural network architectures. It was specially designed to implement neural networks that incorporate any kind of biological parameters. XSim supports different levels of biological modeling, from basic single-cell models to networks with thousands of units.  Unfortunately I cannot  maintain the support or the free distribution of XSim any more. However if you are a former user of this simulator and you still want to get the latest version please contact me.
