Your brain is you!
Everything you think, feel, see, hear, and do is mediated by your brain. It holds your memories, creates your dreams, lets you learn, controls your muscles, and tells your body when to eat and sleep. It's where your consciousness comes from! Pretty cool, huh? Neuroscience is the study of the brain and its interactions with the body. We (Stefanie and Erin) are neuroscience graduate students at Emory University. This website is a way for us to answer all of your neuroscience questions. You can also read questions asked by others.
Here's how it works:
Email your questions to braininfo@gmail.com. You can include your name, grade and school if you want. We'll put your question on this website along with an answer. If you really stump us, we might ask a professor! Check back often for new questions.
- An adult brain weighs about 3 pounds.
- Your brain is 78% water - similar to the consistency of Jello or yogurt.
- When you're born, your brain is about 10% of your body weight.
- By the time you are grown up, it's only 2%. It doesn't shrink - your body grows!
- There are about 100 BILLION neurons in an adult brain! That's about 20 times more than the number of people on the planet!
- Babies have even more neurons - about 200 BILLION!
- Each adult neuron makes 1,000 - 10,000 SYNAPSES, or connections, with other neurons.
