Human brain processes every sensation, including pain, that you experience every day, but did you know that the brain itself has no pain receptors. Of course, there are lots of tissues as well as bone and other types of tissue that edge your brain, so if you thud your head, or experience any other sort of injury, you will most certainly still feel it.
Higher IQ More Dream
It's a proven fact that the higher your IQ (Intelligence Quotient) the more you dream. Scientists studying the phenomenon of dreams have discovered that while everyone dreams, the frequency of dreams is remarkably higher than above average intelligence. Of course, if you never seem to dream, don't take that as a sign of a lack of intelligence. Research has also shown that in many instances, your dreams last only a few seconds, hardly long enough to even register. Then again, most of us don't remember any of our dreams, and it's usually only for a few seconds, when we have been awoken in the middle of a dream, that we even remember them at all.
memory
Each time humans blink, their brain kicks in and keeps things enlightened so the whole world doesn’t go dark each time they blink, which is about 20,000 times a day. You can recall about seven facts at any one time in short term memory, but over the long term your brain has to forget things to make room for new memories.
male female brain
Human brain has a complex connection between each nerve. If every person on the planet simultaneously made 200,000 phone calls, there would be the same total number of connections as in a single human brain in a day. It is only just bigger than your two fists. On average, the male brain (approx 1.4kg) is slightly bigger than the female brain (approx 1.26kg).
speed
There are 100,000 miles of blood vessels in the brain. Information can be processed as slowly as 0.5 meters/sec or as fast as 120 meters/sec (about 268 miles/hr). The average number of thoughts that anyone experience each day is 70,000. While awake, human brain generates between 10 and 23 watts of power which could be enough energy to power a light bulb. The human brain uses 20% of the total oxygen as well as uses 20% of the blood circulating in human body. If human brain loses blood for 8 to 10 seconds, a person will lose consciousness. The human brain can live for 4 to 6 minutes without oxygen, and then it begins to die. No oxygen for 5 to 10 minutes means the permanent brain destruction. Human brain is about 2% of your total body weight but uses 20% of your body's energy
More active at night
Strange as it may seem, human brain actually shows more activity at night than during the day. Despite all the thinking, and complex calculations you do every day, your brain actually shows more activity at night. In fact, when you shut down at night, to go to sleep, your brain wakes up.
facts about dreams
Most people dream about an hour or two at night and have an average of 4-7 dreams each night. Brain waves are more active while dreaming than when awake. Five minutes after a dream, half of the dream is forgotten. Ten minutes after a dream, over 90% is forgotten. If someone awakes during a dream, it is much more likely to remember the dream than if one slept until a full night's sleep. Since dreams are more than just visual images, so blind people do dream.
two sides of brain
Each half of the brain controls the other half of your body. In right-handed individuals (which comprise 91% of people): the right side of the brain controls: musical talent, fantasy, imagination, dreams, drawing, and painting. The left side of the brain controls: mathematical ability, ability to solve logic problems, controls language skills, remembers names, dates, and facts.
brain deveolpment
The neocortex makes up about 76% of the human brain and is responsible for language and consciousness and it is much larger than in other animals. The cerebral cortex grows thicker as humans learn to use it. Reading aloud and talking often to a young child promotes brain development. The study indicates that learning new things helps the human brain to change very quickly. The capacity for such emotions as joy, happiness, fear, and shyness are already developed at birth. The lips and cheeks can experience touch at about 8 weeks and the rest of the body around 12 weeks.
most complex machine
The brain is the most complex machine in the universe. It has over 100,000,000,000 nerve cells each with up to 150,000 connections. Each cell is connected to 25,000 others. Brain contains 100 billion neurons, 100 thousand miles of blood vessels and it is made of 75% water.
