Hippocampus CA3 pyramidal cellSomaI Na,t.Subthreshold membrane potential oscillations are blocked by bath application of tetrodotoxin (TTX), a potent Na(t)-current antagonist, in rats 3-17 days old (Psarropoulou C and Avoli M, 1995171 ). 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 (Steinhäuser C et al, 1990 [rats ]292 ).
