Table 1.

Number of units active at baseline and the number of units responding to flash as a function of desflurane concentration in eight rats

	Desflurane concentration
	2%	4%	6%	8%
Baseline*	53±25	47±16	47±18	46±24
Early response*	70±22%	80±18%	79±18%	92±5%
Late response#	71±25%	67±29%	54±34%	60±33%

Responding unit counts are in percent of baseline.
