This chapter focuses on the types and distributions of the main voltage-gated ion channels currently known to exist within the dendrites of CA1 pyramidal neurons, neocortical L5 pyramidal neurons, cerebellar Purkinje cells, and olfactory bulb mitral cells. The focus of this chapter is intentionally limited to these four distinctly different types of central neurons because a substantial amount of high-quality information is available concerning their dendritic voltage-gated channels and because they express a wide range of different types of dendritic electrogenesis. The chapter begins with a short survey of the known dendritic voltage-gated ion channel types and their modulation. This is followed by a look at the distributions of these channels across the entire axis of the four cell types. Lastly, a section is presented to introduce some current ideas on how dendritic voltage-gated channels might impact on the physiological functioning of these neurons.

Keywords: voltage-gated ion channels; pyramidal neurons; Purkinje cells; dendritic electrogenesis; mitral cells
