There are approximately 100 billion neurons in the human brain
The human brain has 100 trillion synaptic connections
There are about 3 million miles of axons in the human brain
There are over 1,000 disorders of the brain and nervous system

At least 30 million neurons in the entire visual cortex are activated by the single image of a house or face
For centuries, people thought that the heart, not the brain, was important for memory. The expression "memorize by heart" is derived from this old belief
Perception, Learning, Memory

Botox temporarily paralyzes muscles by interfering with acetylcholine, which transmits nerve signals to muscles. Sales of the wrinkle-softening toxin Botox totaled $309.5 million in 2001
In 2002, the US government spent close to $19 billion treating and preventing drug abuse

What Is Neuroscience?What Is Neuroscience?Development The weight of the human brain triples during the first
year of life, going from 300 grams to 900 grams When children are six years old, they can understand
approximately 13,000 words; high school graduates know at least 60,000 words

What Is Neuroscience?
Sex Differences The number of neurons in the
neocortex of females is 19.3 billion; in males, the number of neurons in the neocortex is 22.8 billion
The brain of the great physicist Albert Einstein weighed 1,230 grams. This is far below the average brain weight of 1,400 grams
In 2000, 495 doctorates were awarded in neuroscience; 39.4% of these new PhDs were women
