Short term memory is one of the problem which face more people.We normally prefer the long term memory so as to remember learned things.During eighteenth century Joseph Addison as a writer said that “Man is distinguished from all other creatures by the faculty of laughter,” he was not only correct but also, perhaps unwittingly, drawing attention to a vital characteristic of our species.

There are several ways of improving brain capacity.Some of them are,Sleep, music and diet.For example, did you know that children laugh some 300 times a day, whereas we miserable adults are closer to 50 if we’re lucky?

Laughter is important because when we laugh we reduce our stress levels. Laughter leads to a decrease in the amount of cortisol flowing through our system. That is why it is always helpful when someone diffuses a difficult situation by making us laugh. Research has shown that laughter also improves the immune system and leads to better problem solving. So it’s better to listen or view things which may lead us to lough for the betterment of our brain development.

In addition, music is another source of comfort. There are quite a few misleading claims currently being made for the effect of music on the brain, mainly by those with a proprietary product to sell to parents wanting the best for their growing child! Unfortunately, just as there is no magic formula for a brain-expanding diet, you cannot become more naturally intelligent simply by listening to certain kinds of music. Nor will listening to music guarantee a good memory.

But, research has shown that music, as well as being extremely enjoyable, can help in a number of ways. Like reducing stress levels, aid relaxation, and influence our mood. In addition our heart beat will reduce in speed if we are listening to music with a slow, stately beat. Repetitive music can help induce a state of trance. And the soothing undulation of a lullaby has for generations sent us to sleep as infants!.

Also Georgi Lozanov suggests that different kinds of music affect us differently. Classical and romantic music is an ideal accompaniment to taking in new information, while baroque is better for processing or reviewing information. Many people find that music inspires them to be more creative. A growing number of people assert that they remember things better to music, but I have not yet seen any conclusive evidence and prefer to remain open-mindedly agnostic about it. Common sense would suggest that, in some situations, music will be competing for the learner’s attention, while in others it may helpfully complement it. It would also seem to be the case that different personalities respond differently to music.

Also sleep is another way of feeding our mind. We are supposed to know that our brain needs more sleep than we currently tend to have. Although individual needs differ, and generally as we get older we need less sleep, most of us function best on eight hours per day. There are well known exceptions, of course, like Margaret Thatcher, who apparently only needed a few hours.

However, for most people, if we don’t get enough sleep, then, not surprisingly, our brain functions at well below its capacity if we do not have enough sleep. That is why sleep deprivation is an effective way of breaking down people’s resistance. During the day, your mind is constantly taking in new experiences.

Our brain needs deep sleep, sometimes called REM sleep (rapid eye movement), when we are also often dreaming. It is at these times that your brain is processing the experiences of the day. Studies in animals have shown that the neurotransmitter acetylcholine is being produced in REM sleep, a chemical essential for healthy neural networks and therefore for memory. Consequently, deep sleep has been shown to aid the process of forming memories. When your brain is asleep, its speed slows right down for most of the time, producing what are called theta and delta waves.

Recently it has been suggested that, during REM sleep, your brain also transmits at an extremely fast rate, about 40 cycles per second, and these have been called gamma waves. It is no accident that you say you will “sleep on it.” A number of researchers have noticed that if you review something before you go to sleep and again when you wake up, you tend to remember more of it.

In fact, when we are asleep, we go through a number of cycles, each taking about one and a half hours, each moving from a lighter sleep into a deeper sleep and back again. Going through a number of these complete cycles is critical for our mental health. Darkness is important for encouraging the pineal gland to produce the neurotransmitter melatonin, an essential chemical for ensuring that our body clock functions effectively.

A dramatic example of how our brains are affected by upset time rhythms is experienced whenever we fly across major time zones.It is has been confirmed that there really are some people who favor the mornings and some the evenings. There are also distinctly better times of the day for doing things. In the mornings, most people take in new information best, while the afternoons  except immediately after lunch are better for reviewing and processing.

However, there are significant individual variations from this general pattern. Days are, broadly speaking, times for taking in experiences, nights for processing them. In addition, at a micro level within the day, Georgi Lozanov has suggested that we need to aim for periods of high energy, then relaxation, then energy, then relaxation, and so on. Most of this is common sense. But somehow, perhaps because we lead such busy lives, the powerful role of sleep is often forgotten, as are the natural cycles that necessitate processing time as well as task time.
