active) electrical properties of neurons. Here we will describe only the passive (vs. We will show that neurons are electrical device and learn what enables neurons to become “electrifying”. Your brain uses about 20% of your oxygen and caloric intake.In this module we will discuss the "Electrifying brain – passive electrical signals". When in love, the brain releases the same cocktail of neurotransmitters and hormones that are released by amphetamines, leading to increased heart rate, loss of appetite and sleep, and intense feelings of excitement. The Nervous system transmits messages to the brain at the speed of 180 miles per hour. The left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body. The average length of the human brain is about 167 mm and its average height is 93mm. The average human head weighs about 10 pounds. On an average, 100,000 to 1,000,000 chemical reactions takes place in our brain. On an average the weight of an adult female brain is about 1275 grams. Neurons continue to grow throughout human life. Nerve impulses to and from the brain travel as fast as 170 miles per hour. It is estimated that there are over 1, 000,000,000,000,000 connections in the human brain. Information travels at different speeds within different types of neurons. In a lifetime, your brain’s long-term memory can hold as many as 1 quadrillion (1 million billion) separate bits of information. The total surface area of the human brain is about 25,000 square cms. The width of an average human brain is 140 mm. When we touch something, we send a message to our brain at 124 mph.Ĭold weather improves human memory and concentration. If you spread it out, your brain would be about the size of a pillowcase. The human Brain uses 20% of our body energy and makes up only 2% of our body weight. The Human brain stops growing at the age of 18. The human brain is very soft like butter. The Human brain is the most powerful computer which has the processing speed of 3000+ Ghz The human brain is made up of more than 10 billion nerve cells and over 50 billion other cells and weighs less than three pounds. The human brain is capable of creating more ideas equivalent to that of the atoms of the universe. The Human brain constitutes 60% of white matter and 40% of grey matter. Or any other encyclopedia for that matter. The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. The human brain can read up to 1,000 words per minute. The average human brain weighs about 3 pounds. Men listen with the left side of the brain and women use both sides of the brain. The adult human brain is about 2% of total body weight. Our Brain has over 100 billion nerve cells. Only four percent of the brains cells work and the remaining cells are kept in reserve. Your brain generates as much energy as a small light bulb even when you’re sleeping.Īs we get older, the brain loses almost one gram per year. The brain operates on the same amount of power as 10-watt light bulb. The brain is much more active at night than during the day. The brain continues to send out electric wave signals until approximately 37 hours after death. The base of the spinal cord has a cluster of nerves, which are most sensitive. The right side of the human brain is responsible for self-recognition.Īny damage to brain cells cannot be repaired completely. In other words, some people can taste words or hear colors. An average adult male brain weighs about 1375 grams.Ī neglected child brain can be substantially smaller than that of a healthy child.Ī condition called synesthesia can cause senses to overlap.
