To meet this requirement, and other metabolic needs of the neurons, approximately 20 per cent of the blood flow is directed to the brain. Lack of adequate supply of blood to the brain can result in cerebral strokes or haemorrhages.

Scientists have reversed ageing in mice

Scientists have partially reversed the ageing process in mice using genetic engineering. These mice showed signs of new growth of the brain and testes, improved fertility, and the return of a lost cognitive function. Scientists from Harvard and the University of New South Wales are working on the various aspects of the study. They are of the opinion that a major breakthrough in the research will help develop drugs that will restore youthfulness in human cells.
