A lot of changes took place in body while the development of humans
started.The important and farmost thing to consider is the development
of brain.if this is not taken place there would be no difference
between we and animals.According to charles Darwin theory the parts that are
used mostly in our body will grow stronger generations to
generations,that we R not used for generations will be reduced
gradually.the same theory applies to Brain also.when man started
living in lands and fields leaving trees,he started walking with two
back arms(bipedal walking).gradually those arms shaped to legs form,in which the total
body pressure can be bared.thus some energy saved.the tails reduced
because of not useing them.thinking leads brain to take extra
energy,thus a lot of oxygen through blood carried over to the
brain.getting extra content lead the brain to grow strong and made
path to grow bigger.Our brain has 3crores of neurons,and 5 to 10 times to
that brain cells.every thing of our will be commanded by the
brain.from 35 years of age for every day 1000 brain cell will be died
every day,and will not be produced again.thus man loses his memory day
to day in old age.not only that hearing power,tasting,and control over
some body parts and so many.our brain takes 20% of our body oxygens and calories,and for every 70
seconds 1 liter of blood flows in.if few minutes of blood circulation
stopped to brain fatal happens.it may be either paralosis or death.
how much amount of our brain we are using?is it complete?can we
develop our brain?We used to hear that only 10 to 20% of our brain we are using,and
remaining 80-90% are wasting.Recent research proved that wrong,every
part of brain will be activated atleast some of the times.now a days we R Cing a lot of advertisements stateing that we improve ur brains memory power through some excersizes.how can be it possible?
the brain can be divided into some parts according to tasks it perform.the left part of the brain controls our thoughts and makes them resonable,and language.the right one decides
creativity.and so many other parts will be activated for different
tasks.in recent researchs revealed that the persons who knows more
than their mother tounge,and persons who learns music are more
cleverer than others.It happend just because by doing all these things it will
be practiced to bring several brain parts to activation.while solving
a problem all these parts are come to activation in time.we can
compare this with difference between using 256 RAM and 512 RAM in
computers.this is the cause for some to be intelligent,and some one
normal.so normal can also become intelligent by developing his skills
in extra regions.in some times the person whom we thinks to be normal
gives extraordinary ideas,this is because the several brain parts
activation taken place just for some time.u can prctice to bring those
always activate by some concentration excersizes.
some truths about brain

*All our commands,and info from or to brain will happen as small
electric signals of very low frequency.when a thunder bolt hit a human
a high frequency will flow all over body.the brain cannot analyze that
much fast frequency so there is no question of knowing pain or any
thing else.all this happens in flip of seconds.that means death with
no pain.
* every parts suffered pain will be analyzed by the brain,but the
brain couldnt identify even if it cuts into two.thats why most of the
operations to brain happens in mans consious stage.
* now a days so many gadgets are available in market to do our daily
wise calculations.but it will give no excersize to brain.that means we
are keeping our brain in latent position.so,beware of using those, the
consequences are intangible but very effective.
finally the theme that I wrote this big hammering artical
is whether the brain can be a super computer?
Ofcourse it is not possible.because the capability of computer depends
up on its data flow frequency.that means the greater its power the
greater its frequency, intact the data flow will be fast.
our brain cells can only consume and analyze a little frequecy
has to say very low electric signals.in the case of high power just C
the case of hitting by thunder bolt.
The greater ability we have and supercomputers not is
learning through experience,intution.
so Brain and super computer Both have their own limitations.
