The TIFGroup is a NeuronGroup which implements a group of conductance based neurons with exponentially decaying AMPA and GABA conductances. The model has an absolute refractory period and tries to implement the in every aspect to implement the conductance based neuron model used in Vogels and Abbott (2005).

In contrast to other neuron models in Auryn like for example the IFGroup the evolve() function of the TIFGroup does not use vector operations, but is implemented in a simple for-loop. In the particular case of absolute refractoriness this allows to save to time in the evolve function. When a neuron is refractory the integration of membrane variables can be skipped.

TIFGroup implements the problably simples and fastest neuron model that comes with Auryn.
