The temporal relationship between the slow wave and the spike bursts was studied in the fasted and the fed states in conscious dogs implanted with serosal electrodes on the jejunum. A fully automatic computerized method processed more than 225 h of recording. For each slow wave cycle that contained a spike burst, the program computed the cycle duration and the times elapsed from the beginning of the cycle to the onset and to the end of the burst. In the fasted state as well as after feeding, the spike bursts began and ended at any time within the segment of the slow wave cycle on which spike activity occurred. These results indicate that in vivo in the dog jejunum, the temporal relationship of the slow wave and spike bursts is not fixed. They suggest that the slow wave allows the spikes to occur during limited time intervals, but does not determine their precise location and duration within these intervals. Furthermore, differences existed in the patterns of the slow wave and in its relationship with spike activity (period, location, and duration of the segment on which the spike bursts occurred) between the various phases of the migrating myoelectric complex in the fasted state and the fed state.
在植入空肠浆膜电极的清醒犬中，研究了禁食和进食状态下慢波与棘波爆发之间的时间关系。一种全自动计算机化方法处理了超过225小时的记录。对于每个包含棘波爆发的慢波周期，该程序计算周期持续时间以及从周期开始到爆发开始和结束所经过的时间。在禁食状态以及进食后，棘波爆发在慢波周期中出现棘波活动的时间段内的任何时间开始和结束。这些结果表明，在犬空肠的体内，慢波与棘波爆发的时间关系并不固定。它们表明慢波允许棘波在有限的时间间隔内出现，但并不决定它们在这些间隔内的精确位置和持续时间。此外，在禁食状态和进食状态下，移行性肌电复合波的不同阶段之间，慢波的模式及其与棘波活动的关系（棘波爆发发生的时间段的周期、位置和持续时间）存在差异。
