The electrical activity of the different regions of the colon was recorded from chronically implanted electrodes in six different species. Two types of spiking activity were identified as common to all the species: short spike bursts (SSB), lasting less than 5 sec, occurring in series and localized at one electrode site, and long spike bursts (LSB) of more than 5 sec in duration and propagated over a colonic segment. No relationships were found between the anatomical or feeding peculiarity and the spiking activity of a species. Intense SSB activity was always associated with the formation of dried pellets. The propulsion of digesta seemed to be related to the LSB, their preponderance being associated to the shortest transit times.
通过长期植入的电极，记录了六种不同物种结肠不同区域的电活动。两种类型的尖峰活动被确定为所有物种共有的：短尖峰爆发（SSB），持续时间少于5秒，成串出现且局限于一个电极部位；长尖峰爆发（LSB），持续时间超过5秒，并在结肠段传播。未发现物种的解剖结构或进食特性与尖峰活动之间存在关联。强烈的SSB活动总是与干粪粒的形成有关。消化物的推进似乎与LSB有关，LSB占优势与最短的转运时间相关。
