Name:
 iaf_cond_exp_sfa_rr - Simple conductance based leaky integrate-and-fire neuron model.

Description:
iaf_cond_exp_sfa_rr is an iaf_cond_exp_sfa_rr i.e. an implementation of a
spiking neuron using IAF dynamics with conductance-based synapses,
with additional spike-frequency adaptation and relative refractory
mechanisms as described in Dayan+Abbott, 2001, page 166.

As for the iaf_cond_exp_sfa_rr, Incoming spike events induce a post-synaptic
change  of  conductance  modelled  by an  exponential  function.  The
exponential function is  normalised such that an event  of weight 1.0
results in a peak current of 1 nS.

Outgoing spike events induce a change of the adaptation and relative
refractory conductances by q_sfa and q_rr, respectively.  Otherwise
these conductances decay exponentially with time constants tau_sfa
and tau_rr, respectively.
