“Grow” your intelligence

By working your brain, you change it physically. You can improve your mental performance, and develop your capacity to perform well in intelligence tests, by keeping your brain active. One way of doing this is to make sure you incorporate puzzles and thinking challenges into your routine.

Scientists studying rats and mice have found that when their research subjects are put in a more cognitively stimulating environment—for example, one with more wheels and ladders—their brain cells grow more connective branches (dendrites). The stimulation primes their brain to make new connections. In rats and mice (and in human beings) a brain with more connections thinks faster and more effectively.

Neuronal plasticity Brain scientists also report amazing examples of groups of people who have reshaped their brains by repeating a particular activity over a long period. They call the brain’s capacity to change “neuronal plasticity.”

A taxi driver never forgets … Drivers of the celebrated black cabs in London must memorize routes across the city in order to pass an exam colloquially known as “the Knowledge.” This requires them to study hard and commit to memory a very large number of routes. A study in 2000 at University College, London, showed that memorizing all these routes had physically enlarged the part of the hippocampus in the brain that governs use of data concerning movement through space. The taxi drivers had literally grown part of their intelligence.

Pay attention, please … Most people who practice meditation are engaged in training their attention while they are meditating. A study at Massachusetts General Hospital in 2005 investigated the brains of individuals who regularly practiced Buddhist “Insight” meditation, in which meditators focus their attention on breathing and sensory stimuli. The study found that Insight meditators had thicker tissue than non-meditators in the area of the brain (part of the prefrontal cortex) that governs attention and the processing of sensory information.
