睡眠不是一种单一的状态，而是一组复杂的大脑过程，它支持许多生理需求。众所周知，睡眠剥夺会影响许多动物的注意力，这表明睡眠的一个关键功能是调节注意力。相反，需要更多注意力的任务会驱动睡眠需求和睡眠强度。注意涉及到根据其相对显著性来过滤传入刺激的能力，这可能需要整个大脑协调突触活动。这种能力可能只有随着支持两种关键睡眠功能的相关神经机制的进化才成为可能：刺激抑制和突触可塑性。我们认为，睡眠和注意力可能是共同进化而来的大脑状态，它们相互调节。
Sleep is not a single state, but a complex set of brain processes that supports a number of physiological needs. Sleep deprivation is known to affect attention in many animals, suggesting that a key function of sleep is to regulate attention. Conversely, tasks that require more attention drive sleep need and sleep intensity. Attention involves the ability to filter incoming stimuli based on their relative salience, and this is likely to require coordinated synaptic activity across the brain. This capacity may have only become possible with the evolution of related neural mechanisms that support two key sleep functions: stimulus suppression and synaptic plasticity. We argue here that sleep and attention may have co-evolved as brain states that regulate each other.
