摘要
In rat neocortical slices activation of glutamate metabotropic receptors with glutamate, quisqualate and 1S,3R-ACPD caused a spike-evoked afterdepolarization which replaced the normal afterhyperpolarization. In some neocortical neurons the afterdepolarization reached action potential threshold causing prolonged self-sustained firing. These effects of metabotropic receptor activation were similar to the action of muscarinic agonists in the same preparation.
