How Kids Can Learn So Much So Quickly by Dr Jack Lewis
Neuroplasticity – the ability of the brain to adapt to the specific demands of the environments in which a person spends their waking hours. It occurs via reinforcement of connections between some brain cells (neurons) and weakening those between others. Neuroplasticity is at an all time high during childhood. This is primarily why kids seem to be able to absorb information like a sponge and pick up new skills so effortlessly.
Children’s brains are in a special, highly-adaptive state, enabling them to pick up new abilities very easily and develop a large repertoire of them very rapidly in preparation for adult life. That’s not to say that you cannot teach an old dog new tricks – it’s just that older brains have to put in more time and effort to pick up new skills. As with all things, the more you do something the easier it becomes. It may sound odd but, in a manner of speaking, you need to learn to learn, and then it comes easy. Older people tend to not bother trying to learn as intensively as during childhood, so when they do try, as they are out of the habit of learning, it all seems much harder. The trick is to never stop learning. Get back in the habit of learning, as you were naturally inclined to be during childhood, and learning becomes much easier, because your brain goes back into the “learning mode” i.e. your brain’s neuroplasticity increases.
The more a specific mental function is practiced, whether performing coordinated body movements, reading, engaging in conversation, experimenting with imagination, music, gadgets, whatever, the quicker, more accurately and more easily it can be performed the next time round. From day-to-day these improvements are usually not very noticable. But across a timeframe of weeks or months these tiny, incremental progressions add up into great leaps forward.
Any particular mental function involves a different set of brain areas that must communicate with each other via rapid fire electrical messages. Connections between brain areas that regularly work together to perform a specific mental function are strengthened, whilst others that are rarely used are eventually chopped away. That is one of the most surprising findings about brain development. You would think that the more you learn the more brain cells are created and the brain gets larger. In actual fact the complete opposite is true. Over the course of adolescence, as the ability to write, calculate, communicate, use tools, acquire knowledge and many other skills improve, a whopping great 33% of the brain’s neurons are trimmed away. And that’s a fact. Adolescence is all about pruning away brain cells that aren’t providing a useful function in order to free up precious resources and make way for extra connections to be made between brain cells that ARE often used.
The upshot is that the more complex, rich and varied a person’s experiences over the course of their childhood, the more complex, rich and varied the connections between its brain cells; ultimately translating into a broader repertoire of capabilities. The importance of a parent’s influence on the development of a child’s brain cannot be over-emphasised. Parents either do or do not provide a stimulating environment in which to stretch and challenge their child’s brain. They may or may not efficiently guide, nurture and encourage the development of skills, new experiences and abilities. This does not have to incur expense. Encouraging a young brain to explore and engage with their environment, to communicate openly and to feel free to ask as many questions as they want is key to enabling a brain to develop.

MORE Brain Training offers a few new games, many of which are similar to the old ones, some are plain dull, but a handful are really quite novel and clever. Overall I would say it is a bit tougher on the old synapses than the predecessor (that's a good thing)

Exercise is good for health, we all know that. That said it is also clear that the whole world is utterly fixated on the benefits to the body. The considerable potential benefits of physical exercise for the brain are invariably overlooked. As proof of these benefits continues to trickle in and the exact mechanisms by which exercise improves brain function gradually makes itself apparent, I'm guessing we'll find ourselves increasingly inclined to take regular exercise for our brain's sake.

There is an awful lot of great information out there on the internet. But, as we have all no doubt experienced, there is also a load of old rubbish to wade through before you find those nuggets of wisdom. When I comment on twitter, anything labelled with #neuroformed (short for neuroscience-informed) is, in my opinion, a grain of brain-related wheat - a news article, abstract, insight or quote - that I've chosen to give my seal of approval to, flagging it as interesting, relevant and worth a few moments of your attention
