• Patch recordings yield an approximate channel density of 45 pS/micron^2 (compared with 28 pS/micron^2 in dendrites) in juvenile rats < 4 wks of age, rising modestly to 56 pS/micron^2 (compared with 61 pS/micron^2 in dendrites) in older rats Show Other

• Recordings using the intracellular perfusion method showed no differences between the I-V characteristics of CA1 and CA3 neurones for this current. In contrast to this, the steady-state inactivation of both types of neurones was significantly different Show Other
• Inactivation of dendritic Na channel contributes to the attenuation of activity-dependent backpropagation of APs Show Other
• Slow inactivation of sodium channels in dendrites and soma will modulate neuronal excitability in a way that depends in a complicated manner on the resting potential and previous history of action potential firing Show Other
