Development of IPSP and IPSC amplitudes
| Property | Stimulation Amplitude, V | P8 | P16 | P27 |
|---|---|---|---|---|
| Threshold IPSP amplitude, mV | Threshold | −1.8 ± 0.4 (n = 9) | −0.8 ± 0.1 (n = 11) | −1.1 ± 0.3 (n = 12) |
| Suprathreshold IPSP amplitude, mV | Threshold + 40 | −5.7 ± 1.2 (n = 9) | −4.3 ± 0.8 (n = 11) | −4.8 ± 0.6 (n = 10) |
| Threshold GABAA IPSC amplitude, pA | Threshold | −27.3 ± 5.9 (n = 4) | 30.8 ± 10 (n = 4) | 25 ± 5.8 (n = 4) |
| Suprathreshold GABAA IPSC amplitude, pA | Threshold + 40 | −39.8 ± 6.4 (n = 4) | 125.9 ± 26.9 (n = 3) | 128.4 ± 28.1 (n = 4) |
Values are shown as means ± SE; n, number of cells.
IPSP, inhibitory postsynaptic potential; IPSC, inhibitory postsynaptic current.
