Control	40.7 ± 3.2	Control	15.3 ± 4.0
NR1-1a	31.5 ± 3.7	NR1-4b	16.6 ± 3.3
NR1-4a	34.7 ± 10.5	2A	34.7 ± 5.2^*
GFP	33.2 ± 1.7	2B	27.4 ± 3.2^*
2A	59.7 ± 8.0^*	2B+NR1-1a	47.7 ± 9.3^*
2B	78.7 ± 8.8^*
2B+NR1-4b	95.2 ± 20.2^*

Values are in current density (pA/pF). CGCs were cultured in 25 mm K⁺ and cultured cortical neurons were from P1 rats. *p < 0.05 versus control. n> 6 cells for each group.
