Expand description

Brunel-Wang 2001 — LIF with NMDA (Mg²⁺ block), AMPA, and GABA synaptic conductances for decision-making and working memory circuits.

Key feature: voltage-dependent NMDA conductance via Mg²⁺ block factor 1 / (1 + [Mg²⁺]/3.57 · exp(-0.062·V)). This creates positive feedback that sustains persistent activity in recurrent circuits.

The single-current interface routes external input to i_ampa_ext; recurrent AMPA/NMDA/GABA inputs are zero (use the multi-arg step_full() for network simulations).

Brunel, N. & Wang, X.J., J Comput Neurosci 11:63, 2001.
