LOS ANGELES: The human brain comprises nearly 100 billion cells called neurones that are linked to one another by neural pathways with an estimated 100 trillion connections.
It is the most complex organ in the body, controlling every bodily function.
Although all human brains have the same anatomy and functions, the precise pattern of connections and interactions vary with individuals, which is the source of the variation in human behaviour.
The brain makes us what we are and who we are, defining our individuality and common humanity.
The study of the brain and mind is the last frontier in medical science. There has been much progress in the last few decades. For example, the brain’s capacity to reorganise pathways, create new ones, and in some instances, even create new neurones, has replaced previous knowledge that the formation of new neurones cease shortly after birth.
