A more complex synaptic mechanism featuring up to 4 exponential components (1 rise and 3 decay). Currently there is only an implementation of this in a NEURON mod file. Attributed added can be gmax_2, tau_decay_2, gmax_3 and tau_decay_3. The overall conductance is effectively a linear sum of 3 independent conductances, all with the same rise time and different decays. Note that the gmaxes are specific for each conductance and scaling is calculated for each individually, so the maximum total conductance (gmax + gmax_2 + gmax_3) will only be reached when tau_decay = tau_decay_2 = tau_decay_3, otherwise peaks will not overlap. |
