2 What Is Neuroscience? Function of the Brain and Nervous System

3 What Is Neuroscience? Neuroanatomy: Structure is Key to Function

4 What Is Neuroscience? Function of Neurons   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

5 What Is Neuroscience? Diseases of the Nervous System Alzheimer’s Parkinson’s Stroke Epilepsy Paralysis Obesity?

6 What Is Neuroscience?   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

7 What Is Neuroscience? How Drugs Work   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

8 What Is Neuroscience? Genes And Behavior

9 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

10 What Is Neuroscience? Evolutionary and Comparative Perspective

11 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
