The brain’s mysterious tendrils may control time perception

In a recent study on mice, scientists from the University of California,
Irvine (UCI) in the United States discovered a critical role for tiny
antenna-like organelles once thought to be relics from our ancient past in
maintaining a sense of time.
Cilia are projections made of microtubules on many cells, including those
of multicellular organisms like us.
Most cilia in the human body, known as primary cilia, are immobile, despite
their standard function in motility (either pushing cells around or
transporting items near their surface).
