Spatio-temporal filtering properties of a dendritic cable with active spines: A modeling study in the spike-diffuse-spike framew
The spike-diffuse-spike (SDS) model describes a passive dendritic tree with active dendritic spines. Spine-head dynamics is modeled with a simple integrate-and-fire process, whils...
