A Way to Measure Pain!

Using brain scans, a team at the Oxford University has carried out a series of studies which have shown distinct differences between the brains of people in pain and others who are not.

“Pain seems to increase the blood flow to certain parts of the brain roughly in proportion to the amount of pain felt, and we can measure that activation in a brain scan,” the team’s leader Prof Irene Tracey said.

What the scientists have found is that the brain possesses what they call a “pain matrix”, with such feelings typically activating more than a dozen parts of the brain, ‘The Sunday Times‘ reported.

This is in contrast to other senses such as vision or hearing, where stimuli are generally fed to just one part of the brain for interpretation.

DNA -‘Creates that Initial Spark Between Two People’

Love at first sight? But, what creates that initial spark between two people? Well, it’s body odour, created by the genes involved in the  immune system, and more specifically the DNA, say experts.

According to Tamara Brown, a Croatian geneticist based in Zurich, a section of the DNA called human leukocyte antigen plays a key role in searching for “true love” and the key lies in “secret signals” one picks up from another’s body odour.

“It’s chemistry of attraction. Somebody might not be Brad Pitt-good-looking, but there’s just something about them and you can’t put your finger on it,” Dr Brown was quoted by ‘The Sunday Times‘ as saying.

In fact, the catalyst for her study was the “T-shirt experiment”, a Swiss study at the University of Bern carried out in the mid-1990s that screened the DNA of male and female volunteers, then asked the women to smell T-shirts the men had worn for two nights and rate them for “attractiveness”.

The women, it turned out, preferred the smell of men with genes that were different from their own in this HLA section. All the women, except for those on the contraceptive pill, seems to affect their sense of smell.
