The Brain Manual

- The step-by-step guide for men to achieving and maintaining mental well-being.

by Dr Ian Banks


Break a leg, burn your hand or cut your finger and the injury is obvious. They're the equivalent of a flat tyre - an easily observed fault. Problems under the bonnet are trickier to deal with. So it is with the human body - the workings inside the head are often beyond comprehension.

Fortunately, you don't have to be a brain surgeon or a rocket scientist to undertake simple maintenance of your mental faculties. But you do need a manual to follow - the new Brain Manual from Haynes.

Written by Dr Ian Banks, author of the NHS Direct Health Care Guide, a frequent broadcaster, President of the European Men's Health Forum and a practising casualty doctor, the Brain Manual emphasises positive steps to improved mental well-being.

There are tips for healthy eating and an explanation of the biophilia effect (why getting close to nature makes us feel better). Relationships and stress are covered as is the effect of ageing on the brain. Brain malfunctions and disorders are explained - with information about how to avoid them or how to cope with their effects.

Functional problems, such as the effects of a stroke, are also included. And there's a useful guide to the likely effects of alcohol and other recreational drugs.

Of course, many people prefer to ignore what is happening ?under the bonnet' but they are dismissing a serious problem. Nearly 13 million working days were lost to stress-related illness in 2004. Some of the causes of stress are not obvious - deaths from heart attack or stroke increase significantly on the day of a big football match for instance.

Some of the many "fact or fiction?" questions answered in :

All brains start life as girl brains.
True! The default brain in the developing foetus is female.

People can hear colour.
Strange as this may sound, it is fact. Approximately 1 in 25,000 people have this condition called synaesthesia - meaning joined sensation.

Humans only use 10% of their brains.
This is a popular myth but false.

Testing Boosts Memory

By Jennifer Cutraro

Students who break into a cold sweat at the thought of a pop quiz might feel better once they learn about a side effect of test-taking: The practice appears to enhance memory, possibly even more than studying. What's more, according to a new study, testing also helps students remember material that wasn't on the exam in the first place.

Over the past several years, cognitive scientists have documented a phenomenon called the "testing effect," in which taking a test, rather than studying, boosts an individual's ability to remember the material later on. The research led psychology doctoral student Jason Chan and his colleagues at Washington University in St. Louis, Missouri, to wonder whether testing also affects memory for untested materials.

To test the theory, the team had 84 undergraduate students read a passage about toucans, a topic the researchers believed would be unfamiliar to psychology undergraduates. After reading the passage, one-third of the students were dismissed, one-third were asked to read an additional set of study materials that covered the same information as the original passage, and one-third were asked to take a brief short-answer test on the original material. The next day, all participants returned to take a final short-answer test, which included questions from the previous day's brief test as well as new questions.
