Find Out How Your Brain Grows Old! Posted: 25 Apr 2012 11:39 AM PDT Hey people! Today, lets learn about how the human brain ages. We are all well aware of the fact that all parts of our body age with time and the brain is no exception. No, don’t worry I’m not giving a lecture on the human brain. But I think it is very interesting to know the stages in aging of the brain. To start with the development of the brain starts within four weeks of conception itself. So it’s a very crucial period for both the mother and her baby. This is why a shortened gestation period may cause some psychological or behavioral problems in the child as he or she grows. During this time the brain produces twice the number of neurons it will need but only those that reinforce with use remain. By the time a child enters his or 6th year the brain weighs 95 percent of its adult weight. Some people believe that our brain starts aging at the onset of puberty. In adolescence the brain is said to be fully grown but the process of “wiring” still continues at its pace. It will be interesting to know that between the ages of 20 and 90 the human brain looses up to 5 or 10 percent of its weight and the grooves of the brain also widen during this period. At the age of 20 our brain finally reaches adulthood. Now comes the deterioration part. The human brain starts deteriorating right from the age of 45. Most men and women during this period experience problems with memory, reasoning and comprehension. By the time you are 80 years old your brain shrinks in size because of loss of water. This leads to deterioration of cognitive abilities and verbal memory. The main factors that can help you prevent early aging of your brain are education, exercise and rest. Learning something everyday, indulging in good exercise and sleeping well will prevent your brain from aging fast. Good food habits are obviously a must. Factors like hypertension and stress are known to accelerate the Source: Infographics – This is How Your Brain Ages Hope you love to read these too |
Will India succeed in convincing the Security Council about Agni-V? Posted: 25 Apr 2012 11:01 AM PDT The tussle between the Indian government and the Security Council of the United Nations is further prolonged. India in her attempt to grab a permanent seat in the Security Council and be on par with the other nations is eager to launch Agni V which is part of the Agni series. On the other hand the UN Security Council does not approve of this as it predicts a rift between India and China posing as a threat to peace and security of both the countries. The problem actually arises because Agni is the most powerful missile which has the capacity to travel a distance of 500 KM and carry multiple nuclear warheads to reach targets in Asia, Australia, Africa and parts of Europe. Till date only permanent members of the UN Security Council could boast possession of such missiles. India being a non permanent member and possessing something more powerful is not acceptable to its rivals. Whether the Security Council approves of India's appeal or not still remains a mystery at this point. What happens next? Lets wait and watch! Here are the couple of videos about Agni-V: 3D Model: India DRDO Agni-V ICBM Watch: The Agni V Inter-Continental Ballistic Missile launch Meet the woman behind Agni-V success Hope you love to read these too |
