====== The TIFGroup ====== 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 implements the conductance based neuron model used in [[http://www.jneurosci.org/content/25/46/10786.short|Vogels and Abbott (2005)]]. It is used in at least one of our [[examples:sim_coba_benchmark|examples]]. **Side remark:** 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 computation time when a neuron is refractory the integration of membrane variables can be skipped.
