This Is What Your Brain Does When You’re Not Doing Anything
When your mind is wandering, your brain’s “default mode” network is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other......»»
Worm genetics reveal important pathways for sleep regulation
Although the regulation of sleep—how much, when, and how sleep occurs—is mainly considered to be controlled by the brain, sleep deprivation also affects the body, and signals from the body can affect sleep. However, the ways in which the body reg.....»»
Gene Expression in Neurons Solves a Brain Evolution Puzzle
