A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.

Scientists have long wondered why humans and other animals need to sleep. One potential mechanism is that sleep is required to restore synaptic connections and homeostasis in the brain...

Those with classically positive lifestyles, behaviors had different brain connections to those with classically negative ones
The researchers point out that their results resemble what psychologists refer to as the ‘general intelligence g-factor’: a variable first proposed in 1904 that’s sometimes used to summarize a person’s abilities at different cognitive tasks. While the new results include many real-life measures not included in the g-factor – such as income and life satisfaction, for instance — those such as memory, pattern recognition and reading ability are strongly mirrored.

A team of scientists led by the University’s Centre for Functional MRI of the Brain has investigated the connections in the brains of 461 people and compared them with 280 different behavioural and demographi...
