BR_me_ 4.8_Neurotransmitters IA Final Script AMNH. Nov 20, 2010 Karen de Seve Ana Camila Benitez -Martinez NEUROTRANSMITTERS INTERACTIVE FINAL SCRIPT Main idea: Neurotransmitters are brain chemicals that control the action between nerve cells – and therefore they control everything our bodies do. Visitor experience: Users will experience the action as if they are inside the brain of the main character. Users will control the action by making choices at key points in the scenario, thus controlling brain function. At certain points, users can choose to find out more information about the role of a particular neurotransmitter via a pop-up box. Learning objective: Visitors will understand that brain chemicals control our emotions and actions based on the events (incoming stimuli) that we experience each moment of each day. 1.- INTERACTIVE VIDEO CHAPTERS BRAIN PANEL MID SCREEN BODY PANEL NT.0 ATTRACT LOOP PRESS ANY BUTTON TO BEGIN NT.1A.1 INTRODUCTION Ever wonder how your brain controls the way you feel? Happy, sad, hungry or tired, it’s all because of changes in chemicals— called neurotransmitters—inside your brain. Press the (book icon) button to find out more about highlighted terms. Watch what happens when you make different choices. Neurotransmitter levels will rise or drop… IN THE BRAIN … and the brain will tell the body what to do. Ready to try it? A Yes, let’s start B No, repeat video 1/7 IN THE BODY BR_me_ 4.8_Neurotransmitters IA Final Script AMNH. Nov 20, 2010 Karen de Seve Ana Camila Benitez -Martinez NT 2A.1 SMELL IN THE BRAIN IN THE BODY Imagine you are relaxing and reading a book. Many nerve cells are signaling each other in the brain. SCENT detected Mmmmm. I smell cookies baking. ALERT: Smell signals received I want a cookie, but Mom said to wait for dinner. WANTING STOMACH growls ALERT: Brain activity changing CONFLICT DOPAMINE rises HEART RATE speeds up What should I do? A Obey Mom and wait B Get a cookie anyway NT 3A.1 RESIST IN THE BRAIN IN THE BODY ALERT: “Stop” signal activated Brain tells body not to go for the cookie. FRUSTRATED DOPAMINE drops HEART RATE speeds up BREATHING QUICKENS That was a tough choice! I’ll play outside to forget about the cookie. 2/7 BR_me_ 4.8_Neurotransmitters IA Final Script AMNH.

MOTIVATED HEART RATE speeds up STOMACH growls I can’t wait to taste that cookie! NT 3B.2 WARNING IN THE BRAIN Don’t eat the cookies! ALERT: Memory activated Brain remembers warning from Mom.

DOPAMINE drops FRUSTRATED HEART RATE speeds up BREATHING quickens Mom won’t catch me, but still, I’ll play outside to forget about the cookie. NT 4B.1 BUSTED IN THE BRAIN IN THE BODY Mmmmm. This cookie looks yummy! DANGER!! DOPAMINE drops STRESS HORMONES rise SCARED HEART RATE speeds up BREATHING quickens Oh no! I’m busted! Uh oh! What do I do? A Run away!

Nov 20, 2010 Karen de Seve Ana Camila Benitez -Martinez 2.- POP-UP SCREENS POP-UP NT Neurotransmitters Neurons communicate using chemical messengers called NEUROTRANSMITTERS. A neuron sends an electrical signal that triggers the release of a neurotransmitter. Like a lock and key, the chemical attaches to a special receptor on another neuron. The message is sent. Some neurotransmitters tell the next neuron whether to fire or not, while others may influence how the neuron responds to other signals. The brain reacts in different ways depending on the neurotransmitter and the brain region signaled. POP-UP_DOPAMINE Dopamine, among other things, is a key messenger in the brain’s “seeking system,” which generates desire. When dopamine is released, it helps motivate you to find the things you need. Once you achieve your goal, dopamine is released again to strengthen the memory of what caused the good feeling. POP-UP_ENDORPHINS Endorphins are brain chemicals released by the pituitary gland, the hypothalamus and many other neurons throughout the brain to help reduce pain and stress. Endorphins also activate your pleasure centers when you accomplish a goal, when you exercise and even when you eat chocolate! POP-UP_OCYTOCIN Oxytocin plays a key role in the bonding process. New moms and people in love generally have high levels of this neurotransmitter in their brains. Scientists think that oxytocin may decrease during a period of separation but increase again during a reunion. Oxytocin is released by the pituitary gland. POP-UP_STRESS Stress hormones include cortisol and epinephrine. These brain chemicals are released when something makes you worried, angry or agitated. Their function is to get your body and mind ready to defend yourself if necessary, or to run away. 7/7
