文摘
- •
It was shown that recurrent excitatory transmission in the frog tectum column.
- •
Is inhibited by the endogenous acetylcholine.
- •
The inhibition occurs with a delay of ∼80 ms.
- •
Muscarinic AChR antagonist atropine eliminates this effect of endogenous ACh.
- •
Thus, the delayed inhibition is mediated by the activation of muscarinic AChRs.
