Eat healthy and be healthy is a simple and important statement. We are what we eat, it means that healthy food is so important for both our physical as well as mental health. Along with healthy and pure food some exercises are also important for good health and fitness. Yoga is a very effective exercise that provide good physical as well as mental health.

Exercising in your 70s 'may stop brain shrinkage'
22 October 2012 - Regular exercise protects the brain, experts suspect

Exercising in your 70s may stop your brain from shrinking and showing the signs of ageing linked to dementia, say experts from Edinburgh University. Brain scans of 638 people past the age of retirement showed those who were most physically active had less brain shrinkage over a three-year period. Exercise did not have to be strenuous - going for a walk several times a week sufficed, the journal Neurology says. But giving the mind a workout by doing a tricky crossword had little impact.

The study found no real brain-size benefit from mentally challenging activities, such as reading a book, or other pastimes such as socialising with friends and family. When the researchers examined the brain's white matter - the wiring that transmits messages round the brain - they found that the people over the age of 70 who were more physically active had fewer damaged areas than those who did little exercise.

And they had more grey matter - the parts of the brain where the messages originate. Experts already know that our brains tend to shrink as we age and that this shrinkage is linked to poorer memory and thinking. And previous studies have shown that exercise helps reduce the risk of dementia and can slow down its onset. But scientists are still baffled about why this is.

'Intellectual & Emotional Capabilities' Slowly Eroding...

Mutations in the human brain are making us stupider, new research shows
Monday, November 12, 2012, A Stanford University professor presented evidence Monday that mutations in the human brain — brought on by advances in society that have made survival less stressful — are eroding our intellectual and emotional capabilities.

We've become so smart, we’re getting stupid, new research shows. A Stanford University professor presented evidence Monday that mutations in the human brain — brought on by advances in society that have made survival less stressful — are eroding our intellectual and emotional capabilities. Gerald Crabtree, lead author of the study published in the journal Trends in Genetics, claims the brain drain has been going on for centuries.

Crabtree, a professor of pathology and developmental biology, suggested our intellectual peak came when humans were mostly nonverbal and were stressed out trying to think of ways to not get eaten by wild animals. He said survival was once a driving force for intelligence. But the development of agriculture and the rise in urban living has probably weakened the natural selection towards intelligence and made us less smart. Luckily, the loss of brain wattage is so slow that advances in technology should solve our problems before we all turn completely stupid.

Crabtree estimated that within 3,000 years, humans will endure two or more mutations harmful to our intellectual and emotional stability. “I think we will know each of the millions of human mutations that can compromise our intellectual function and how each of these mutations interact with each other and other processes as well as environmental influences,” Crabtree said. “At that time, we may be able to magically correct any mutation that has occurred in all cells of any organism at any development stage,” he said. “Thus, the brutish process of natural selection will be unnecessary.”

Granny says she don't want nobody smokin' `round her `cause she don't want dey's cigarette smoke drivin' her crazy...

Study: Passive Smoking Increases Risk of Dementia
January 09, 2013 - A new study in China is the first to show a significant link between second-hand smoke and dementia. So-called passive smoking, inhaling other people's cigarette smoke, is already known to cause heart disease and lung cancer.

China is the world's largest consumer of tobacco, with 350 million smokers. It also has the most dementia sufferers, a number that is growing rapidly as the population ages.

Researchers from King's College London and Anhui Medical University interviewed nearly 6,000 people over age 60 in five Chinese provinces, to assess their smoking habits, exposure to cigarette smoke, and level of dementia. They found 10 percent had severe dementia. Lead author, Dr. Ruoling Chen, said this study highlights the need to protect people from environmental tobacco smoke.

The World Health Organization says only 11 percent of the world's population lives in countries with laws that create smoke-free public places. Chinese government efforts to promote such environments have met with limited success. The new report is published in Occupational and Environmental Medicine.

possum wonderin' if the mouses have human memories?...

Human Stem Cells Restore Memory, Learning in Mice
April 22, 2013 - Scientists have successfully transplanted human stem cells into brain-damaged mice and helped them recover their memory and learning skills.

The study was carried out by Dr. Su-Chun Zhang, a professor of neuroscience and neurology at the University of Wisconsin-Madison. According to the study, the implanted human stem cells transformed into two common types of neurons, GABA and cholinergic neurons. "These two neuron types are involved in many kinds of human behavior, emotions, learning, memory, addiction and many other psychiatric issues," said Zhang in a statement. For the experiment, Zhang treated the human stem cells with chemicals known to promote their development into nerve cells.

Scientists have successfully transplanted human stem cells into brain-damaged mice and helped them recover their memory and learning skills.

After receiving transplanted cells, the mice performed better in tests that measure learning and memory. One test in particular had the mice transverse a water maze, which challenged them to remember the location of a hidden platform in a pool. Zhang said the damage to the mice brains was done in an area called the medial septum, which connects to the hippocampus by GABA and cholinergic neurons and is “fundamental to our ability to learn and remember.” The transplanted cells were placed in the hippocampus. Once implanted, the cells began to respond to chemical directions from the brain and began to specialize to connect to the appropriate cells in the hippocampus.

Zhang said the process is akin to removing a section of telephone cable. “If you can find the correct route, you could wire the replacement from either end,” he added. While the study does provide some hope for future treatment to brain damaged humans, Zhang says the stem-cell therapy is unlikely to be the immediate benefit. "For many psychiatric disorders, you don't know which part of the brain has gone wrong," he said. The study was first published in the current issue of Nature Biotechnology.
