Our brain is plastic, and it’s never too late to muscle our neurons and improve our cognitive performance.
Radoter is not so bad
True. Long-term memory is anchored all the more as we regularly relive our memories or repeat our learnings. This is how the points of contact between neurons, synapses, are consolidated. The more we take these synapses (evoking the memory), the more this “path” widens and becomes passable, facilitating circulation. Conversely, little used, they eventually disappear. “Synaptic plasticity” works both ways.
Memories have no smell
False. Our experiences are very much linked to our senses: we often associate sounds, tactile or gustatory sensations. But the smoke of Proust’s madeleine is more powerful than its taste! People with neurodegenerative diseases have been asked to find a memory related to a pack of tobacco. The study shows that being able to touch cigarettes and especially smell their smell made it possible to raise reminiscences better than the simple evocation of words associated with smoking.
Sleeping makes us forget
True and false. Sleep is crucial in the memorization process: it is the moment when the brain sorts the information to keep and that to erase (the details of a discussion, for example). It is during rest and especially periods of deep sleep that our personal experiences and recent memories are reactivated, consolidated, and stored in long-term memory.
One of the best memorization techniques dates back to antiquity
True. Called “the palace of memory”, it would have been invented by a Greek poet, popularized in Rome by Cicero, and validated by neuroscience very recently. It is a question of mentally “tidying up” what you want to memorize in a room that you can easily visualize. When we want to find this memory, the brain will return to the room with which its image is associated.
Memory: Sport preserves our memories
True. Physical activity protects all of our cognitive faculties and reduces the risk of dementia. And it’s always worth getting started! One study, conducted on elderly people with very mild cognitive impairment, showed that those who started aerobics three times a week felt real benefits (unlike those who only followed a healthy diet). Combining the two was even more profitable.
