N-甲基-D-天門冬氨酸受體

N-甲基-D-天冬氨酸受體（N-methyl-D-aspartate receptor，NMDAR），簡稱NMDA受體，為穀氨酸鹽受體，是一個主要的分子裝置，控制突觸的可塑性與記憶功能^[2]。

NMDA受體是一種離子型穀氨酸鹽受體的特別型態。NMDA（N-甲基-D-天冬氨酸）是一種選擇性致效劑，可以與NMDA受體結合，但是無法和其他穀氨酸鹽受體結合。NMDA受體的結合，會導致離子通道非選擇性地開啟，使陽離子通過，進而使平衡電位改變至接近0毫伏特。NMDA受體進行活化，必須依賴電壓，這會導致離子通道會阻擋細胞外的Mg²⁺與Zn²⁺離子通過，並允許Na⁺離子與少量Ca²⁺離子流入細胞，以及使K⁺離子流出細胞，並保持電壓的依賴性^[3]^[4]^[5]^[6]。
