Objectively measuring loneliness in the brain, as opposed to asking people how they feel, could give clarity on, for example, the connection between loneliness and depression. It could also shed some light on addiction.
The ability to measure loneliness may make it far easier to design targeted interventions.

Science shows friendship is critical for our happiness, health, and longevity.
* In the 1970s and 1980s, some epidemiologists and sociologists showed that socially isolated individuals over age 66 had a 30 percent increased risk of early mortality.
* Studies reveal that social connection improves cardiovascular functioning, reduces susceptibility to inflammation and viral disease, sharpens cognition, reduces depression, lowers stress, and even slows biological aging.
Friendship requires at least three things: It should be long-lasting, positive, and cooperative. Friendship nearly always includes a willingness to help, especially in times of crisis.
In short, friendship is creating bonded groups that act as a buffer against life's stresses.
It is common knowledge that we need to sleep to be our best. And constant sleep loss has serious effects, including death.
Sleep is a neurological activity, and still, sleep-deprived cr...
Sleep, according to deep research on flies, has a function of reversing the ancient biochemical process of oxidation. Without sleep, there is no restoration possible.
Sleep studies prove it is worse than starvation, as early studies (19th century) conducted on puppies showed that they died in about five days if deprived of sleep and kept in motion.
... or ROS is a molecule that builds up in the intestines of animals that are denied sleep.
Studies conducted on fruit flies and mice showed rising levels of ROS when kept in sleep deprivation.
Antioxidants, when given to sleep-deprived flies, made them healthy and active again, proving that the artificial restoration is possible.

From birth to our early teens, we have far more links between brain cells. The excess brain mass is very adaptable and allows children to learn very quickly.
But the adaptability comes with a price. The large and complex network in the brain is still busy growing and not as capable of forming memories efficiently as in adulthood. Consequently, long-term memories created in our first three years of life are the least stable and prone to be forgotten as we age.
