Octopus vulgaris maintained under a 12/12h light/dark cycle exhibit a pronounced nocturnal activity pattern. Animals deprived of rest during the light period show a marked 'rebound' in activity in the following 24h. 'Active' octopuses attack faster than 'quiet' animals and brain activity recorded electrically intensifies during 'quiet' behaviour. Thus, in Octopus as in vertebrates, brain areas involved in memory or 'higher' processes exhibit 'off-line' activity during rest periods.
在12/12小时光照/黑暗周期下饲养的普通章鱼表现出明显的夜间活动模式。在光照期被剥夺休息的动物在接下来的24小时内活动会出现明显的“反弹”。“活跃”的章鱼比“安静”的动物攻击速度更快，并且在“安静”行为期间电记录的大脑活动会增强。因此，与脊椎动物一样，章鱼中参与记忆或“高级”过程的脑区在休息期会表现出“离线”活动。
