Abstract
To investigate the functional role of dendrites of thalamocortical neurones, we have used our one-compartmental model to construct a multi-compartmental model with dendritic regions chosen according to a representative soma-to-dendritic terminal path of an X cell of the cat dorsal lateral geniculate nucleus. The multi-compartmental model with dendritic low-threshold Ca2+ and delayed rectifier K+ channels yields more accurate results than the one-compartmental model when simulating tonic firing and oscillatory activities, and provides a useful means for the study of propagation of excitation on the dendrites.
