In spite of efforts to address the organization of the locomotor CPG in walking animals, little is known about the identity and function of the spinal interneuron cell types that contribute to these locomotor networks.

Normally the two timers are in step, and the external cues tend to regularise the internal clocks to the more convenient 24 hour period.

这两部人体时钟在不受干扰时会使人体有一个25小时－－不错，是25小时的生理节奏，两部时钟系统在一般情况下步调是一致的，外界种种因素常常把内部时钟调节到更为合理的24小时一周期。

The first is hardwired: A master clock in the brain regulates a so-called circadian rhythm, which synchronizes activity patterns to the 24-hour day.

"Modern society is chronically sleep deprived; a poll by the National Sleep Foundation in 2001 found that about a third of Americans report sleeping six hours or less during weeknights and 17% of people continue to do so through the weekend," Helen Burgess, PhD, lead investigator, told Medscape.
