Channel conductance density^a distribution in the model layer 5 intrinsically bursting pyramidal cell

Region	Na	K DR	CaL	K A	K Ca	I h
Soma	400	60	6	5	2	0
Adjacent to soma	150	20	6	5	1.8	0
Basal dendrites	12	2	8	5	2.4	0
Proximal apical	20	2	8	5	2.4	0
Distal apical	15	2	4	5	1.2	0.5
End segments	6	2	6	5	1.8	0
Tuft	4	1	3	5	0.9	0

The apical dendritic densities indicated pertain to the most proximal and most distal compartments in the apical dendrite (excluding the tuft), with the density in intervening compartments linearly interpolated between them.

^aIn all cases, the density is expressed in mS/cm² and refers to the density applicable when all channels are open.
