Comparison of burst properties during MK-801 exposure in experiments measuring NMDA receptor-mediated EPSCs (EPSC) and those measuring whole cell current responses to bath NMDA after EPSC blockade (Extrasynaptic).
| Experiment Type | EPSC | Extrasynaptic | |
| n | 5 | 19 | |
| incubation time | min | 4.5 ± 0.7 | 4.9 ± 0.5 |
| number of bursts | 6.6 ± 1.4 | 6.2 ± 1.2 | |
| number of spikes | 106 ± 34 | 97 ± 13 | |
| RMP | mV | -60.9 ± 4.7 | -58.2 ± 1.7 |
| Vm during bursts | mV | -50.0 ± 2.0 | -53.7 ± 2.0 |
| depolarisation | V.s | 202.4 ± 73.6 | 187.6 ± 34.6 |
Average membrane potential (Vm) during bursts was calculated from the burst onset till the return to the baseline resting membrane potential (RMP). Depolarization was calculated from the integral of the membrane potential above RMP over this same period summed across all bursts for each cell.
