| 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. | ||
