Men, women process feelings differently

Gorkha Post




Swiss researchers have revealed an alternative of how men and women’s brain work differently as it has long been said that both brains is wired in a different way.

A large- scale study by a research team at the University of Basel focused on deciding the gender-dependent relationship between feelings, memory performance and brain activity.

With the help of 3,398 test subjects from four sub-trials, the researchers were able to demonstrate that females rated emotional image content – particularly negative content – as more emotionally stimulating than their male partners did.

In the case of natural images, however, there were no gender-related differences in emotional appraisal. In a consequent memory test, female participants could freely recall fundamentally a larger number of pictures than the male participants.

Surprisingly however, women had a specific preference over men when reviewing positive pictures. “This would suggest that gender-dependent differences in emotional processing and memory are due to different mechanisms,” says study leader Dr Annette Milnik.

Using fMRI information from 696 test subjects, the researchers were also able to show that stronger appraisal of negative emotional image content by the female participants is connected to expanded brain action in motoric regions. The result would support the common belief that women were more sincerely expressive than men, clarified Dr Klara Spalek, lead author of the study.

This study is important, because many neuropsychiatric diseases also show gender-related differences.

The results will be published in the latest issue of the Journal of Neuroscience.

Urinary, respiratory tract infections may double stroke risk

NEW YORK — People who are suffering from urinary or respiratory tract infections may face nearly double the risk of heart attacks and strokes than obesity, researchers have warned.

The study — led by a researcher of Indian origin — found that if the frequency of these common infections causing hospitalisation continues for a longer period it may even lead to death.

Patients diagnosed with any one of these common infections were three times more likely to die than those without prior infection after developing heart disease, and almost twice as likely to die if they had a stroke.

“Our figures suggest that those who are admitted to hospital with a respiratory or urinary tract infection are 40 per cent more likely to suffer a subsequent heart attack, and 2.5 times more likely to have a stroke, than patients who have had no such infection, and are considerably less likely to survive from these conditions,” Rahul Potluri, researcher at Britain’s Aston University, said in a statement.

The effects of the common infections were of similar magnitude among the people suffering from diabetes, hypertension, and cholesterol, researchers said.

“It is notable that infection appears to confer as much, if not more, of a risk for future heart disease and stroke as very well established risk factors such as high blood pressure and diabetes,” Potluri added.

Researchers conducted the study over 34,027 patients who had been admitted with a urinary or respiratory tract infection with an age and sex-matched control group without infection.

Factors such as age, gender, ethnicity, obesity and tobacco use, as well as medical conditions including excess cholesterol, high blood pressure, diabetes and kidney disease, heart failure and atrial fibrillation were also taken into account.
