The role of GABA neurons in the central circadian clock

The research team led by Dr. Daisuke Ono and Prof. Akihiro Yamanaka of the Graduate School of Medicine, Nagoya University, along with collaborators, has revealed that inhibitory neurons (GABAergic neurons) of the central ...

Researchers show evidence of cellular clocks in cells

One of nature's most familiar phenomena is collective behavior—fish swimming in schools, locusts marching together, birds flocking. The same thing happens in humans, with individual cells synchronizing into circadian rhythms, ...

Finding a gene that regulates sleep

What keeps us awake—and helps us fall asleep? The answer is complex, but involves what are called circadian rhythms, which are found in all species with sleep-wake cycles—physical, mental, and behavioral changes that ...
