Development of brain function in humans
Development of Brain Functioning in Foetus and Newborn
Rose describes how the human brain develops before and after birth, saying "Early
brain development in the foetus and newborn is itself associated first with a massive
proliferation of cells, and then by a steady drop in numbers, but the space once
occupied by the lost cells is taken up by an increase in the branching and synaptic
connections made by those that remain."
Role of REM Sleep in Infants
Lavie pointed out that in animals which are born fairly mature, such as sheep,
REM sleep is low and near adult level. In species which are born immature, "such
as rats, cats, and humans, initial amounts of paradoxical (REM) sleep are very large.
In kittens, during the first ten days of life paradoxical (REM) sleep occupies 90
percent of their time." {10}
We already saw that Jouvet hypothesised that one of the roles of REM sleep in
animals was to train the neural networks which are related to instinctive behaviour.
We also saw that during the first few days after birth the actual amount of REM
sleep in babies is very great and Lavie concluded that "it plays a vital role in
the maturing stage of the nervous system" and that "it is possible that REM sleep
is particularly important for procedural types of learning in which humans acquire
motor and perceptual skills. Since during the first few months of life infants are
busy acquiring new motor and perceptual skills, these findings may also explain
the abundance of REM sleep at that particular time in our life". {10}
Stevens says "REM sleep is thought to play an important role in developing
the infant brain and in activating those neural programmes responsible for basic
and characteristic patterns of behaviour, such as maternal bonding, environmental
exploration and play."
He added that common childhood fears "of the dark, of strangers, of rapidly approaching
objects, are all ... early warning devices put there by evolution because of the
constant dangers in the ancestral environment".
Children do not distinguish between dreams and waking life until they are three
or four years old, but can usually understand the difference when between five and
eight years old.
Changes in Sleep-wakefulness Rhythm during First Year of Infant`s Life
A baby wakes and sleeps roughly every four hours in its first month. This changes
gradually until at about six months "the baby begins sleeping almost through the
night and the sleep-wakefulness rhythm stabilises at twenty-four hours". And so
during the first year "a single and continuous sleep period and a period of continuous
wakefulness begin to emerge, and at the same time a pattern of coordination between
the sleep-wakefulness rhythm and the demands of the external environment slowly
begins to develop".
Memorize tracery games
Free memory improvement trainings. You are about to embark on a mystical journey
that will show you the magical way to acquire a better memory.
There are numerous memory courses out there that promise to improve memory.
These may work for some kinds of memory retention. All eidetic memory consists
of is the ability to return to the moment of experience in the mind and everything
that was experienced will flood into the present immediately. You don’t have to
contrive certain associate events, you just have to return in mind to the experience
and all that was involved comes back in total. It is a visual experience because
I see everything as it was.
If you contemplate that concept you realize that if you can learn to be consciously
present in each moment, you will be able to recall anything you chose by simply
returning to that moment in thought. Perhaps it is the retrieval process
we need to focus on not how to retain certain memories. We must select from the
continual onslaught of information and impression bombardment what we chose to integrate
with our conscious thought. This is why I feel that focused intent is the key to
memory retention and retrieval. Though a good sound and healthy brain is necessary
for this to function properly. If you consider how much information is impinging
your brain at any one moment it is staggering.
What this has to do with creativity is that a truly creative person is never
handicapped by losing the wisdom of prior experience. What the truly creative mind
does is access that certain idea which has already been offered to consciousness.
Then become relaxed, open and free to allow anything new that memory has yet to
resolve. All problems are solvable if you are patient and know that the solution
lies in your intent to find it and your willingness to be open to it.
