Active subthreshold dendritic conductances shape the local field potential

Torbjørn V Ness, Michiel W H Remme, Gaute T Einevoll

The main contribution to the local field potential (LFP) is thought to stem from synaptic input to neurons and the ensuing subthreshold dendritic processing. The role of active den…
