The human brain is very fragile. It has a consistency somewhat like jello: soft and squishy.
On average, your spinal cord stops growing at _____ what age? [Hint lower than 5]

What animal sleeps 90% of the day?

True or False? Your Brain cannot feel pain.
True:
Your brain is the boss of processing pain from the rest of your body, but it actually has NO PAIN RECEPTORS of its own.
Can exercise make you smarter? Why?
YES. Like running or playing basketball, is great for your body and can even help improve your mood. Scientists have recently learned that for a period of time after you've exercised, your body produces a chemical that makes your brain more receptive to learning. So if you're stuck on a homework problem, go out and play a game of soccer, then try the problem again. You just might discover that you're able to solve it.
Name three ways to protect your Brain?
Wear a helmet, don't FALL, wear your seat belt, exercise (this helps with blood flow to your Brain)...

A regular sleep schedule. Follow your natural circadian rhythm. Have a wind-down routine (bath, reading, listening to music). Keep your bedroom dark and avoid bright light, especially blue light, in the evening. Make your bed comfortable and inviting. Use a noise-blocking machine to minimize distracting noise. Use a natural light timer to wake your body in the morning.
How fast do "messages zip through your brain and body"? _____ Miles per hour.
"Messages" speeds about 150 miles per hour (faster than a bullet train)! Some signals as fast 240 miles per hour.
What is the brain's ability to learn NEW things, and change our habits? [Hint re-wire the brain]
___________plasticity
Neuroplasticity.
It is driven by learning, new experiences, and recovery from injury, allowing the brain to adapt to changing environments and unlearn negative habits.

False. The brain can learn how to do new things at any age!
How many thoughts per day do we have?
70,000 thoughts on average. These thoughts are tied to our emotions, memories and movement.
How many "STAGES" of sleep do we go through when we are sleeping?
There are four sleep stages, including one for rapid eye movement (REM) sleep which is when we dream and three that form non-REM (NREM) sleep.
Stage 1 also called N1, normally lasts just 1-7 minutes.
Stage 2. During stage 2, the body enters a more subdued state including a drop in temperature, relaxed muscles, and slowed breathing and heart rate. At the same time, brain waves show a new pattern and eye movement stops.
Stage 3: sleep is also known as N3 or deep sleep, and it is harder to wake someone up if they are in this phase. Muscle tone, pulse, and breathing rate decrease in N3 sleep as the body relaxes even further.
REM. During REM sleep, brain activity picks up, nearing levels seen when you are awake. DREAM TIME
Neurons in the brain generate a small amount of ________ when sending messages back and forth.
Power/electricity. The human brain can generate about 23 watts of power (enough to power a lightbulb).
How many "seconds" does your short-term memory last?
20 to 30 seconds.
True or False? Our brains are shrinking over time.
True.
Modern human brains are smaller than they were 10,000-20,000 years ago, possibly due to efficiency adaptations. But size doesn’t determine intelligence
What percentage of the brain is made of water? [Hint above 50%]
75% of the brain is made up of water. As little as 2% can make your feel foggy with thinking.
True or False? Your Brain is more active at night.
Your brain is more active at night. Its busy processing the day, taking a brain wash to get rid of unsued information. When we dream our brain is just as active when we are awake.
On average how many neurons are in our brain?
FINAL JEOPARDY: How many years would it take to count the neurons (nerve cells in the brain)?
86 Billion neurons in the human brain.
Every single minute, how much blood flows through you brain? ______ (hint ML)
750 ML flows through your brain each minute. One and a half bottles of water.
Why do our brains allow us to feel fear? Why would feeling scared be helpful?
