GET QUOTEThe Triune Brain
Posted on August 28, 2008 - Filed Under Uncategorized
The brain is not only divided horizontally into left and right. It is effectively divided vertically as well. Dr Paul Maclean in 1973 coined the term triune brain to emphasise the three divisions.
(1) The Reptilian brain (or brainstem), which emerges directly from the spinal column and controls the very basic instinctive responses.

Left v Right in our culture
Posted on August 27, 2008 - Filed Under Uncategorized
The distinction between left and right is deep in the human psyche, and is constant amongst all cultures. It has much significance. Right is a synonym for correct. Righteousness is good. The angels sit on God’s right hand. Right in Latin is “dexter”, from which we get dexterity. Left in Latin is “sinistra” from which we get sinister. In French left is “gauche”. About ninety per cent of humans are right handed, and more girls than boys. Read more
Two Brains are Better than One!
Posted on August 26, 2008 - Filed Under Uncategorized
It would appear that the better connected the two halves of the brain, the greater the potential of the brain for learning and creativity. Recent research by Dr. Christine de Lacoste Utamsing at the University of Texas has found that the interconnecting area is always larger and probably richer in nerve fibres in women than in men. We don’t
know why yet, but it has fascinating implications. Read more
Left Brain/Right Brain
Posted on August 25, 2008 - Filed Under Uncategorized
That the brain is divided physically into a left and right half is not a new discovery. The Egyptians knew that the left side of the brain controlled and received sensations from the right side of the body and vice versa.
It is only in the last two dozen years, however, that the true implication of the left/right split has gradually become apparent, through the work of a number of researchers. The most famous are probably Dr. Roger Sperry and Dr. Robert Ornstein of the California Institute of Technology. Their work has won them a Nobel prize.

Educational Technology
“We are only now on the threshold of knowing the range of the educability of man - the perfectibility of man. We have never addressed ourselves to this problem before. ”

Sexual differences in Brain Development

Whilst physical development of the brain is largely complete by age five, there are further well established intervals of intellectual development at ages 6 to 8, 10 to 12 and 14 to 16. It seems that we should try to ensure that educational stimuli should be timed to coincide with these natural periods of development.

Neurons (2)
Posted on August 22, 2008 - Filed Under Uncategorized
About ten weeks before birth, each neuron starts to send out numerous thin fibres to make actual and potential connections with other neurons. The power of the brain is largely a function of the number of neurons and the richness of their connections. Since each neuron can itself make thousands of connections, the potential number of inter-connections in the brain runs into trillions. The key point to remember is that only some of these connections are made automatically. Read more

The average adult human brain consists of some 12,000 to 15,000 million nerve cells. (15,000,000,000).
That is about three times the entire population of the earth. The human nervous system, controlled by the brain, begins its development only 20 days after conception.
Five weeks from conception brain development starts in earnest and after eight weeks the first of two brain spurts begins. At this stage the brain represents half the total length of the foetus (although it is still only ‘/2 inch long!). This is when the neuroblasts begin to grow. Neuroblasts are embryonic cells that will in turn become neurons, or brain nerve cells. The speed at which neuroblasts are now developing is staggering. They are added at the rate of several thousand a minute. Read more
Your Incredible Brain
Posted on August 20, 2008 - Filed Under Uncategorized
The human brain appears over-endowed. It used to be an often quoted statistic that we only use 10% of our potential brain power. The more psychologists have learnt in the last ten years however, the less likely they are to dare to attempt to quantify our brain potential. The only consistent conclusion is that the proportion of our potential brain power that we use is probably nearer 4% than 10%.

Rhinoplasty Surgery
Posted on August 14, 2008 - Filed Under Uncategorized
Perhaps the most sought after and the most wanted part of the face that people want to “reconstruct” is the nose. Every year there is half a million people who are interested in improving the appearance of their nose. They seek a consultation with a Facial Plastic Surgeon. Some people are unhappy with the nose they were born with, and some with the way aging has changed their nose. For others, breathing may be a problem, or an injury may have distorted the nose. Just a slight alteration of the nose can greatly improve one’s appearance. Rhinoplasty (reshaping the nose), could improve one’s looks, self-confidence or as well as one’s health.
