Neuroscientists discover on/off switch in the brain for deep sleep

on off switch

The parafacial zone (PZ) in the brain stem produces half of all the brain’s sleep-promoting activity.

For the first time ever, neuroscientists have used an innovative new method to identify a circuit in the brain that promotes deep sleep, which reinvigorates the brain from its daily activities.

Italian neuroscientist believes human head transplant surgery is possible

Researcher thinks human head transplant surgery is finally possible.

A neuroscientist in Italy believes he’s figured out how to do a full human head transplant. Or body transplant, depending on your perspective. Dr. Sergio Canavero of the University of Turin explains in a recent paper how the procedure would work, describing how a “clean cut” with an “ultra-sharp blade” could leave the two severed spinal cords in the condition to be re-attached. “It is my contention that the technology only now exists for such linkage,” writes the researcher.

Brain rejects negative thoughts

human-brainnnnnnn

No negative thoughts here!

Good news: your brain is hardwired for good news
Bad news: your brain is hardwired for good news

Why don’t people stop smoking even after hearing bazillion public service messages that doing so will give them cancer? Why do people get married even though the rate of divorce is 50%?

Neuroscientists have the answer: it’s because the human brain rejects negative thoughts (and yes, sometimes to the detriment of the brain’s host)…

Sleeping with a Night Light Could Lead to Depression

Sleeping with a night light on could lead to depression.

Neuroscientists believe that even having a dim light on – such as a night light often used in a child’s room – adversely affects the chemical balance and structure of the brain.  Sleeping in anything other than a completely dark room could lead to depression, research suggests.

A Brain Scan Could Help You Find the Perfect Career

Forget interviews, tests and career advisers, a brain scan may soon be the best way to discover your ideal job.

Neuroscientists are getting closer to being able to pinpoint your talents just by looking at the landscape of your mind.  They are slowly mapping the brain so they can match particular areas to particular skills and knowledge.

Neuroscientists Create “Body Swapping” Illusion

Nueroscientists Create “Body Swapping” Illusion 

From the outside, psychotherapy can look like an exercise in self-absorption. In fact, though, therapists often work to pull people out of themselves: to see their behavior from the perspective of a loved one, for example, or to observe their own thinking habits from a neutral distance.

Are Optical Illusions Caused By The Brain Or The Eye?

Are Optical Illusions Caused By The Brain Or The Eye?

 (Left) Isia Leviant’s Enigma. Most viewers say the purple rings appear to fill with rapid illusory motion. (Right) A simplified version that the researchers used in the study. Most viewers report illusory motion lengthwise along the gray stripe.

When viewing the famous optical illusion painting Enigma by Isia Leviant, many people claim to see motion within the colored circles moving against the black and white striped background. Although this optical illusion has been known for a long time, its physiological origins are still unknown.

Hand Transplant Patient Shows Signs Of Sensory Recovery

Hand Transplant Patient Shows Signs Of Sensory Recovery 

Activation of the left cerebral hemisphere during sensory stimulation of the transplanted right palm.  

Four months after a successful hand transplant — 35 years after amputation in an industrial accident at age 19 — a 54-year-old man’s emerging sense of touch is registered in the former “hand area” of the his brain, says a University of Oregon neuroscientist.
