Buildup of a DNA-repair protein in brain cells spurs shut-eye in the fish, a study finds, and similar results in mice suggest the mechanism is widespread in animals.
Dreamers answered experimenters’ questions or solved simple math problems, showing that complex two-way communication between the dreaming and waking world is possible.
Technologies such as noninvasive brain stimulation and virtual reality gaming offer insights into how dreams arise and what functions they might serve.
In mice, the brain’s main glial cell type exhibits distinctive patterns of activity across the sleep-wake cycle and influences the response to sleep deprivation.
The activation of young brain cells in adult mice is necessary not just for forming memories, but consolidating them during rapid eye movement sleep, a study shows.
The gene, aquaporin-4, is critical in rodents for the cerebrospinal fluid bath the brain gets during sleep. It’s now also tied to slow wave electrical activity during deep sleep in people.
After an accident as a teenager, he developed the disorder. He then studied the brain to better understand his own seizures, and now plans to sail around the world to show others with the condition how to push their limits.
From 1969 to 1988, 25,000 infants were born early each year as a result of hot weather, and with global warming pushing temperatures higher, more babies will be at risk for early birth.
