Whilst there is no major reason - and certainly no need - for there to be a reduction in mental powers with ageing, there certainly is conclusive evidence that the provision of constant stimuli improves mental ability.

Almost certainly not. What does deteriorate is the body. Arteries become clogged as fat builds up inside the walls, and once they have passed fifty years of age, up to 50% of people suffer diminution of blood supply, i.e. oxygen feeding the brain. When these arteries are cleaned, patients show a significant reduction in nervousness, […]

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

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 […]

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 […]

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 […]

“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. ”

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.

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 […]

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 […]
