Behavioural states are easy to recognise in healthy neonates with a gestational age of 36 weeks or more. In younger neonates stable behavioural states, as seen at full-term, are not present, but activity cycles exist. In utero stable behavioural states can also be recognised from 36 to 38 weeks onwards. The existence of awake states in utero remains controversial. A close relationship exists between neural mechanisms regulating the behavioural state cycling and those modulating breathing. Our understanding of these is still very limited. The absence of behavioural states or of activity cycles is a very sensitive but non-specific sign of nervous system dysfunction in human perinatal life.
行为状态在孕龄36周及以上的健康新生儿中很容易识别。在较年幼的新生儿中，不存在足月时可见的稳定行为状态，但存在活动周期。在子宫内，36至38周起也可识别出稳定的行为状态。子宫内清醒状态的存在仍存在争议。调节行为状态循环的神经机制与调节呼吸的神经机制之间存在密切关系。我们对这些的理解仍然非常有限。行为状态或活动周期的缺失是人类围产期神经系统功能障碍的一个非常敏感但非特异性的迹象。
