This study shows that IPSCs mediated by a5-subunit containing GABAA receptors are strongly outward-rectifying generating 4-fold larger conductances above -50?mV than at rest. This model shows that synaptic activation of these receptors can very effectively control voltage-dependent NMDA-receptor activation. The files contain the NEURON code for Fig.6 and Fig.7. The model is a single dendritic compartment with one glutamatergic and GABAergic synapse. Physiological properties of GABA synapses were modeled as determined by optogenetic activation of inputs during voltage-clamp recordings in Schulz et al. 2018.
