Expand description

Dendritic NMDA spike model.

Captures the non-linear voltage-dependent Mg²⁺ block of NMDA receptors in dendritic branches. NMDA current has a sigmoidal voltage dependence:

I_NMDA = g_NMDA · B(V) · (V - E_NMDA) B(V) = 1 / (1 + [Mg²⁺]/3.57 · exp(-0.062 · V))

This enables coincidence detection: the dendrite only passes current when both presynaptic glutamate AND postsynaptic depolarisation are present.

Reference: Jahr & Stevens (1990), Schiller et al. (2000).
