Sleep
Editorially reviewed
Self-rated sleepiness, attention tests, eye movements and brain scans measure different consequences of sleep loss. Here is why one reassuring result cannot stand in for all the others.
Breathing
Editorially reviewed
In a laboratory study of 54 healthy women, breathing patterns were associated with different cardiac measures and short-term task performance. The result is specific—not a nervous-system reset.
Nervous System
Editorially reviewed
A small human study offers a concrete way to understand interoception: the ongoing conversation between the brain and the body.
Neuroscience
Corrected

Corrected

Sleep
Corrected
