1. Random Brain Facts

2.  We’ve learned more about the brain in last 20 yrs than all time previous to that  No two brains are identical  Brain matter is mostly water (78%), fat (10%), and protein (8%)  Living brain is so soft it can be cut w/ butter knife---Think Hannibal

3. Random Brain Facts  The adult human brain weighs about 3 pounds (1,300-1,400 gm) Elephant brains = 6,000gm Cat brains = 30 gm  The Brain is ~2% of body weight, but consumes ~20% of body’s energy!  Bigger brains are not necessarily better!  Einstein’s was average size

4. Random Brain Facts  Human brain has over100,000,000,000 neurons  If all neurons were stretched end to end, it would reach to moon and back  Every second, brain receives 100 million messages from the senses  ¾ of body’s neurons are in brain  On the day you are born, all brain cells are in place!! They’re just immature – still developing  Explains why we don’t have memories until 3-4 years old

5. Random Brain Facts  Changing brain:  50,000 neurons are being formed every second during fetal brain development!!!  The Brain is the ultimate “use it or lose it” machine!  Computer/TV has huge impact on brain  Recommend no TV/internet 0-2 yrs

6. Random Brain Facts  Brain disorders cost Americans more than $600 billion a year  Alcohol use in teens is devastating to the pre-frontal cortex!!

7. Bad brain jokes  What does a brain do when it sees a friend across the street? Gives a brain wave  What did the hippocampus say during its retirement speech? Thanks for the memories  What did the right hemisphere say to the left hemisphere when they couldn’t agree on anything? “let’s split”

8. Bad brain jokes  When does a brain get afraid? When it loses its nerve  Why didn’t the brain want to take a bath? It didn’t want to be brainwashed  Why was the neuron sent to the principal’s office? It had trouble controlling its impulses

9. The Brain  By the end of the lesson you should be able to  Describe the structure and function of the brain  State the function and location of all major lobes.  State the location of sensory and motor strip

10. The Brain  “the most complex living structure on the universe” Society for Neuroscience  makes us who we are!!!
