It is a generally accepted fact that brain is the most complex organ of the body. Even in today’s date, when technology has made such rapid progress in almost every field known to man, the brain still remains a less understood member yet the most interesting member of the family.
Even as you read this article, tests and experiments are being conducted in various corners of the world as an attempt to know more about it. It is so special that it has an entire subject dedicated to, namely Psychology.
Varied kinds of researches have been and are being carried out in the field of Cognitive Sciences, and new facts about this fascinating part of our anatomy keep on unraveling.
The brain is made up of mostly protein and fat and is jelly-like to look at. It weighs 1.4 kilos. The cells present in the brain are called neurons whose job is to transmit information from the body to the brain. For this dendrites and axons are used which are collectively called the nerve-fibers.
The brain has many sections. They are:
It is the largest portion of the brain and is divided into four lobes which are:
- Occipital Lobe: Registers visual information
- Temporal Lobes: The brain has two of these. They process auditory information and are also influence emotions, learning languages, pronouncing words and learning in general.
- Frontal Lobes: It is involved in more complicated tasks and functions. Some of them are:
- Voluntary movement of the body.
- Sentence formulation.
- Determining personality traits.
- Parietal Lobe: Processes the sensations that we feel.
Positioned behind the cerebrum, the cerebellum is attached to the brain stem. Some of its functions are:
- Interpreting information sent by the sense organs of the body.
- Regulating motor function of the body.
- Balancing the body.
It is divided into different sections. They are:
- Medulla Oblongata
Some of its functions include:
- Regulating respiration.
- Regulating blood pressure.
- Regulating certain reflexes and the changes occurring in the body when faced with a ‘fight or flight’ situation.
It is located above the brain stem, inside the cerebrum. It is divided into three parts:
It looks after:
- The sleep cycle.
- Sensory function.
- Control of food intake.
The brain is protected by:
- The skull
- Membranes called meninges.
- It is also enveloped by a fluid.
Brain, though shrouded in mystery, has over time revealed many interesting facts about itself. Some of them are:
- A person can permanently damage his or her brain if he or she is deprived of oxygen for ten minutes or more.
- The brain uses 20 percent of the total oxygen that we inhale while breathing.
- The weight of the brain is 2 percent of our total body weight.
- When we are awake, we can light a small light bulb by the amount of electricity that our brain generates.
- 60 percent of our brain is made up of fat.
- If you are dieting, you might just compel your brain to eat itself. They do it as the last ditch effort to prevent starvation. Pretty savage.
- When a person is having an orgasm, his or her brain releases so much dopamine that the brain scans starts resembling the brain of a person on heroin.
- There is a common misconception that consumption of alcohol makes us forget events. However, this isn’t true, because when a person is drunk, the brain temporarily loses its ability to make new memories. So, how can one forget something, which he never remembered in the first place?
- Another misconception about the brains- either the left works or the right works. However, the truth is both parts of the brain work together.
- The chances of having a brain tumor increase considerably with long-term exposure to mobile phones.
- Aren’t rejections acutely painful? They sure are, because rejections are treated by the brains as physical pain.
- How long does it take for the alcohol to affect your brain? Just 6 minutes. So now you know the exact time when the alcohol starts talking instead of you.
- The structure of our brain changes every time we learn something new. Alpha Levo IQ supports brain growth.
- Our memory and personality will not be affected if half of our brain is removed properly.
- Life without music would be meaningless. But did you know that music brings about actions in the same part of our brain which produces dopamine, the ‘pleasure chemical’ which is released while eating and having sex?
- The time of our lives when we have the maximum number of brain cells is the time when we are newborn babies.
- The human brain is home to a trillion glial cells and neurons which run to a hundred billion.
- Per minute, the brain uses one-fifth of a calorie.
- People, with autism definitely have a different behavior pattern. But their brains are virtually the same as those who do not have autism.
- Ever thought that you really think a lot? Well, yes you do. We all have close to 70,000 thoughts per day. It is like our brain is constantly thinking!
- When one sweats for ninety minutes, the brain temporary shrinks. It is almost as if the person has aged a year in just ninety minutes. That is the extent of the shrinkage.
- The heads of babies are bigger so as to accommodate the growing brain.
- Men’s brains are 10 percent larger than female brains.
- Are you progressively finding it difficult to concentrate in class or at work? Don’t worry; it is not your fault. Our attention spans are getting shorter. In a matter of 15 years, our attention span has shrunk from 12 seconds to 8 seconds.
- The brains of children growing up in violent homes are same as the soldiers who have engaged in combat.
