Abstract

Activity within rostral and intermediate ventral medullary surface areas, measured as 660 nm scattered light changes, was examined in six cats, (fiveexperimental, one control site) following 5% CO2 challenges during waking,quiet sleep, and rapid eye movement (REM) sleep states. Activity declined to hypercapnia in all states, with a smaller decline in quiet sleep comparedto waking, and intermediate values in REM sleep, The decline occurred morerapidly, with a shorter latency, during wakefulness, but with a much slower return to baseline than during quiet sleep. During REM sleep, the latencyto nadir and recovery were greater than in other states. Regional patternsof activation emerged which differed in extent of activation between states.
