Facts About Brain
- Our brain is the part of the body which derives input from our senses. While we hear, smell, talk and taste... it was actually our brain that's working. Besides, human brain also capable of thought and language.
- Brain also controls the involuntary actions like breathing and digestion. Various other activities like sneezing and blinking were also controlled by the brain. Besides, the Hypothalamus of the brain is responsible in regulating the body temperature and hunger.
- The average weight of a human brain is just more than a kilo (1,400 grams). But it needs at least 20 percent of the oxygen and blood in the body to perform its complex functions. That`s the reason why our brain gets damaged permanently if it is deprived of oxygen for more than 5 minutes.
- Brain appears to be grey in color. It is because of the brain nerves called Neurons! These neurons are responsible for gathering and transmitting the brain signals. These neurons are connected with each other through 'synapses'. Though it acts as the central nervous system, the brain lacks the nerves that produce pain. A brain can't experience pain even if it is cut!
- Our brain consists of three parts: The Cerebral cortex is responsible for perceiving senses, making moments and thinking in our own way. The Cerebellum coordinates the moments of the body and retains the balance of the body. The Brain stem joins the brain with the spinal cord. - Every time we form a memory, a new connection is formed between the neurons. While working, a brain produces enough energy to light a 20 watt bulb!
- It's a myth that we use only 10 percent of our brains capacity. Every part of the brain is put to use at some time or other. It is also a myth that the brain is divided into left and right parts. In fact, the parts of the brain work together!
- More than 50,000 thoughts are generated in our brain per day. According to an estimate, our brain can store almost 2.5 petabytes (equal to a million gigabytes) of memory! That's as powerful as a super computer.
- Memory can be classified into short-term and long-term memories. We forget things that are not given importance. Forgetting in fact is useful for the brain to delete unused information, so as to make way to the new memories.
