抜粋

It is widely believed that a rise in post-synaptic calcium concentration ([Ca²⁺];) is a necessary step in the induction of long-term potentiation (LTP) (Bliss and Collingridge, Nature, 361 (1993) 31-39). In this experiment, we examine the involvement of voltagegated Ca²⁺ channels (VGCC) in the induction of AP5-sensitive LTP induced by θ-burst stimulation in guinea-pig hippocampal CA1 neurons. The VGCC blockers, Ni²⁺, (25 μM, T -channel blocker) or ω-AgaIVA (60 nM, P-channel blocker), which have no effect on synaptic transmission, suppress 60% or 78% of the Θ-burst induced UP, respectively. This implies that Ca²⁺ entry through VGCC is an important step in this form of LTP.
