the nicest neuron simulator you'll find. Fast (written in C++). Flexible (fully object oriented). Immediate (live manipulation in MATLAB)

xolotl: a fast and flexible neuronal simulator

xolotl is a fast single-compartment and multi-compartment simulator written in C++ with a MATLAB interface that you'll actually enjoy using.

Why use xolotl? This is why:

xolotl is FAST

xolotl is written in C++, and it's fast. In our testing, it's more than 3 times faster than NEURON for single compartment neurons.

xolotl is easy to use

Want to set up a Hodgkin-Huxley model, inject current, integrate it and plot the voltage trace? This is all you need:

x = xolotl;
x.add('compartment', 'HH','A', 0.01);
x.HH.add('liu/NaV', 'gbar', 1000);
x.HH.add('liu/Kd', 'gbar', 300);
x.HH.add('Leak', 'gbar', 1);
x.I_ext = .2;

xolotl has documentation

Unlike certain widely used NEURON simulators that shall remain nameless, xolotl has documentation that actually... exists.

This is what it looks like:

xolotl is fully programmable

xolotl is designed to be used from within MATLAB. It gives you the best of both worlds: the high performance of C++ compiled code with the rich power of all the toolboxes MATLAB has to offer. You can:

  • write functions that pass models as arguments
  • optimize parameters of neuron models using the Global Optimization Toolbox
  • run simulations in parallel across multiple computers
  • have a single script to run the simulation and analyze results
