Why motion makes you sleepy: Insight from fruit flies

People fall asleep on long car rides, fussy babies can be lulled to sleep in a rocking chair, and fruit flies in a tube doze off while spinning in slow circles. The mechanism behind motion-induced sleep is unclear in humans, ...

Rock-a-bye fly: Why vibrations lead to sleepiness

It is common practice to rock babies to sleep. Children and grownups also get drowsy during long car rides. There is something about gentle mechanical stimuli that makes humans of all ages sleepy. Sleep in fruit flies is ...

Stem cell study suggests paths to restore hearing

It turns out that to hear a person yapping, you need a protein called Yap. Working as part of what is known as the Yap/Tead complex, this important protein sends signals to the hearing organ to attain the correct size during ...

New study reveals the cause of sensory changes in starved state

Korean researchers have verified the correlation between animals' sensory nerve activation and behavioral changes caused by insulin secretion in a feeding state. The result provided a clue to identify the causes of unusual ...

Sensory perception is not a one-way street

When we interact with the world, such as when we reach out to touch an object, the brain actively changes incoming sensory signals based on anticipation. This so-called 'sensory gating' has now been investigated by neuroscientists ...

The brain's internal clock continually takes its temperature

Circuits in the brain act as an internal clock to tell us it is time to sleep and to control how long we then stay asleep. A new study in flies suggests a part of that clock constantly monitors changes in external temperature ...

How the brain constructs the world

How are raw sensory signals transformed into a brain representation of the world that surrounds us? The question was first posed over 100 years ago, but new experimental strategies make the challenge more exciting than ever. ...
