The response enhancement could also be eliminated by a potentantagonist of Ca2+-permeable AMPA receptor (CP-AMPAR), which suggests the possibility that Ca2+ influx via glutamate-gatedcalcium channels is related to the changes of [Ca2+]i.

• 另外,反应增强现象还可以被钙离子通透的AMPA受体(Ca2+-permeableAMPAreceptor,CP-AMPAR)的拮抗剂阻断,说明通过钙离子通透的谷氨酸受体内流的Ca2+与胞内Ca2+浓度的改变有关。
