|---|---|---|---|
| Parameter | In vitro | In vivo/anesthetized | In vivo/natural sleep/waking |
| DOWN-UP transition (mV) | 4-10 | 10-15a | 9.6b |

| 7.6 ± 2.1 | 14.6 ± 4.2d | ||
| Change in Gm (nS) | 4-32 | 23e | 27b |

Values are either range or mean ± SD according to which of these was reported. REM, Rapid eye movement.
