Presentation Transcript

  1. What Is Neuroscience? Function of the Brain and Nervous System

  2. What Is Neuroscience? Neuroanatomy: Structure is Key to Function

  3. 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

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

  5. 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

  6. 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

  7. What Is Neuroscience? Genes And Behavior

  8. 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

  9. What Is Neuroscience? Evolutionary and Comparative Perspective

  10. 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
