The brain is 2 to 3% of the body mass but uses 20% of its oxygen and blood flow.
The brain can only survive 4 to 6 minutes without oxygen.
The brain itself does not feel pain.
The brain has the consistency of soft tofu.
The brain is about 75% water.
1,000 to 10,000 synapses (did neuro-scientists really count them?).
The brain and the nervous system are intimately interconnected.
About 30,000 neurons would fit within a pin head.
The brain generates up to 25 watts of power, enough to illuminate a small light bulb.
There are more potential connections in the brain than there are known particles in the universe.
The brain produces a range of brain frequencies that reveal a surprising amount of information as to the physical and mental state of the person being measured.
A human brain weighs an average of 1,350 grams for adults and 375 grams for infants. How do we compare with the other species?
The brain records life experieces as memories. Memories form neuropathways that contain "content" and "feeling."
Perception deeply affects how neuropathways are formed. Experiences perceived as "negative" create negative charges or negative emotions. Experiences perceived as "positive" create positive charges or positive emotions. These emotions impact the body, mind and health.
The brain is exposed to a continuous stream of positive and negative factors and an ever-increasing number of brain stress factors that affect brain balance.
