Resting membrane potential, input resistance and hyperpolarizing effects of morphine (0.1 μM) in S cells from guinea pigs implanted with placebo or morphine pellets
| Pretreatment | Resting Em (mV) | Resistance (MΩ) | Morphine Effects | |
|---|---|---|---|---|
| Hyperpolariz (mV) | Δ Resistance (MΩ) | |||
| Placebo | −46.8 ± 0.8 | 113.1 ± 12.2 | 6.6 ± 0.5 | −26.1 ± 7.9 |
| Morphine | −39.6 ± 1.5* | 102.7 ± 8.6 | 5.8 ± 0.8 | −17.1 ± 4.3 |
Values are means of 18 placebo cells and 28 cells from morphine-pretreated guinea pigs.
