Cerebral capacity - strength of mankind

Human beings are given a great gift - cerebral capacity. However, the question is, how has it evolved?

Cerebral capacity is the ability of a species to use its brain power. It is one of the most debated topics among scientists.

For many years people have believed that human beings can use only 10 per cent of their brain. Due to lack of evidence to support this, many scientists have debunked this theory as a myth.

But the saying, ‘use it or lose it’ seems to apply to the nervous system. During development many new synapses are formed. Studies show that some synapses are eliminated later on in development. The nervous system undergoes a “fine tuning” phase of synaptic development and elimination. Research has shown that if the input to a particular neural system is eliminated, then neurons in this system stop function properly. This is quite apparent in the visual system - complete loss of vision can occur if visual information is prevented from stimulating the eyes (and brain) early in development.

Though this observation may not seem important, our outlook about our brain will change after taking a closer look at the potential it has.

Our brain has great power, we just fail to realise it.
