The average adult human brain weighs 1.3kg (2.8lb). That's twice the weight of a giraffe's brain and three times the weight of a cow's brain. A newborn human baby has a brain that weighs about 350 grams (.8lb), which happens to be the same size as an orangutan's brain.
The size of the brain has very little to do with how smart the animal is. For example, an elephant has a 6kg (13lb) brain, but everyone knows that an elephant is not 5 times smarter than a human. The large size of the elephant's brain is probably how it got a reputation for having such a good memory.
It is a myth that humans only use a fraction of their brains. Even though scientists are still trying to unravel the mysteries of the human mind, every part of the brain is known to have a function. From an evolutionary point of view, larger brains would not have developed if there had not been an advantage to do so.
The origins of this myth are unknown, but it might have originated from a researcher named Karl Spencer Lashley who lived about a hundred years ago. He removed parts of the brains of rats and showed that they could still perform certain tests. The problem with these results are that the rats were only tested on tasks that required the parts of the brain that had not been removed. If the rats had been given other tests, they would have certainly failed.
The amygdala is a small part of the brain, adjacent to the hippocampus, that is believed to react most directly to emotions. From studies using brain scans, it has been shown that events that stimulate the amygdala are remembered better over time. This may be why emotionally significant events are remembered better than emotionally insignificant events.
Because the amygdala is involved heavily with emotions, it is believed to play a role in conditions such as anxiety, depression, post-traumatic stress disorder and phobias.
The human mind thrives on novelty. Without new experiences our brains get bored and lazy. One way to introduce novelty into your life is to read something that isn't your normal fare. Pick up a magazine that you have never read, or look through a section of the newspaper that you normally skip. Go to a library and pick a random book from a random shelf.
This is a great way to learn new and interesting things. You never know when you might discover a new interest or learn something that relates to something that you are currently working on.
