  1. NEURONS & SYNAPSESBy Shannon Hernandez & Mike Shaw of CSNE (ADAPTED FROM “THE TEENAGE BRAIN IN SEARCH OF ITSELF…” WEBQUEST BY ROSEMARY MCCLAIN OF LONDONDERRY HIGH SCHOOL, NH)

  2. PART I: “THE BRAIN & ITS PARTS” Click on the link & read “The Central Nervous System”: Eric Chudler Link Answer the following questions in your notebook: • How many parts make-up the central nervous system? • How many nerve cells are in the brain? • Are there any other special cells in the brain? • List them.

  3. NEXT… “DRAW A BRAIN” Click on the link: “Structures & Areas of the Human Brain& Areas of the Human Brain” In your notebook: • Get the diagram from Ms. Hawks of the brain with the spinal cord. • Write a description to list what each part does. • Show your partner & have them sign-off you did this.

  4. PART II: “PICTURING NEURONS” Click on the link & observe the images of neuron diagrams by Cajal. CajalNeuron Images Click on the link & observe other images of neurons: Neuron images Answer the following questions in your notebook: • Do all neurons look the same? Explain and include a sketch of each from Cajal’s Neurons and choose 3 from the Neuron Images. • What are some differences mentioned in Cajal’s images?

  5. NEXT…“UNDERSTANDING THE NEURON” Click on the link & read about neurons. “Neuroscience for Kids” Answer the following questions in your notebook: • What is a neuron? What is it’s function? • How are neurons similar & different from other cells within the body (make a Venn Diagram to help)? • How many neurons are in the human brain? • Neurons can be classified in two main ways. Describe in detail, providing examples, these two main ways. • Explain the differences between axons & dendrites.

  6. NEXT… “NEURON MODEL” Click on the link:“Neuron Diagram” Answer the following questions in your notebook: 1.Draw a typical neuron. 2.Label the parts. 3.Write a description to list what each part does.

  7. LET’S PLAY… “BUILDING A NEURON” Click on the link & play the game: “Build a Neuron” Screen shot with snipping tool your score & email to Ms. Hawks at ahawks@wcpss.net for credit

  8. PART III: “HOW NEURONS COMMUNICATE” Click on the link & read about synapses: “Neurons Communicate” • Where does information cross and what takes place at this location? • What helps neurons carry out specific functions? Click on the link & watch the video: “Synaptic Function” • What are the “flashes” identified as? • What does a neuron use to communicate?

  9. “NEUROTRANSMITTERS” Click on the link and watch the video: “Crossing the Divide” • What takes place at the synapse? • Where does all of the “action” take place? • What type of neurotransmitter is used along the reward pathway? Click on the link & read: “Types of Neurotransmitters” • Create a chart that lists all the types of transmitters and their function.
