Substantia nigra pars compacta dopaminergic cellDistal apical dendriteI Calcium.Using differential polarization through applied electric fields, cell bodies and dendrites have been activated in effective isolation during intracellular recordings in vitro. In neurons located in the rostral substantia nigra, the dendrites are shown to have both HVA and LVA channels. HVA conductance appears to be exclusively dendritic. By contrast, in more caudally located cells HVA calcium spikes were located principally in the cell body (Hounsgaard J et al, 1992280 ).
