Meditation shown to affect not only brain shape but gene expression meaning you are NOT a prisoner of your genes

Materialist Science  would have you believe that your are a robotic prisoner of your genes. WRONG. Gene expression is determined by our envornoment as well as our mental content. Studies here for you. Oh and then there's Source........

How a Facebook feature in the brain rules your social network

If your social life leaves something to be desired, it might be your brain structure that’s to blame.

A ‘Facebook feature’ deep in the temporal lobe governs the number of friends you are likely to make, scientists have found.

The amygdala, a small almond-shaped structure, has for some time been linked to empathy and fear responses.

Party time: The bigger the size of your amygdala, the wider your social circle

But a study suggests that the larger the amygdala, the wider and more complex is its owner’s network of friends and colleagues.

Volunteers aged between 19 to 83 were asked to complete questionnaires which measured how many regular social contacts they had, and in how many different groups.

Magnetic resonance imaging scans found a positive link between big amygdalas and the richest social lives. Professor Lisa Barrett, a psychologist at Northeastern University in Boston, Massachusetts, reported the findings in the journal Nature Neuroscience.

She said they were consistent with the social brain theory, which suggests the human amygdala evolved to deal with an increasingly complex social world.
Other studies of primates have shown that those living in larger groups tend to have larger amygdalas.

The findings was published in a new study in Nature Neuroscience.

Dr Lisa Barrett, Professor of Psychology at Northeastern University, who took part in the research, said the amygdala got bigger to cope with mankind's more hectic social life.

She added: 'Further research is in progress to try to understand more about how the amygdala and other brain regions are involved in social behaviour in humans.'

Her colleague Dr Bradford Dickerson, an associate Professor of Neurology at Harvard Medical School said: 'This link between amygdala size and social network size and complexity was observed for both older and younger individuals and for both men and women.'

Recently U.S. scientists reported on the case of a woman whose amygdala had been destroyed by a medical condition.

As a result the 44-year-old mother of three felt no fear and constantly put herself in danger. Over the years she had been threatened with a knife, held at gunpoint and assaulted.

Genome failure to predict diseases 
After 20 years of genome research the swaggering  predictions of mainstream Darwinist science of a gene marker for almost every chronic disease have proven almost totally FALSE. Serious article here states the evidence that diseases are mainly not genetically caused and twin studies  which seem so iron clad and irrefutable don't transfer to non twin people. Major failures in our thinking are signalled. As usual mainstream science has  had a near religious faith in the genome project predicting chronic diseases. Because it's so obvious. Or so it seems. Dissident article here with numerous supporting serious authors (listed footnotes) makes the evidence based conclusion that most diseases do not  have a genetic basis.
