Presentation Transcript

  1. Unit 3-A (B):Neural Communicationand Neurotransmitters Mr. McCormick A.P. Psychology

  2. Do-Now(In Journal) • What is a neuron? • Provide an example of information that each of the following neurons may transmit: • Sensory Neurons • Motor Neurons • Interneurons • What causes neurons to fire?

  3. Neural Communication What part of theneuronreceives messages from other cells? What part of the neuronsends messages to other cells?

  4. Neural Communication • Neurons interact so closely that, even with a microscope, it is difficult to determine where one neuron ends and another begins • Synapse: • The junction between the axon tip of the sending neuron and the dendrite of the receiving neuron • Synaptic gap (less than one-millionth of an inch wide)

  5. Neural Communication • Neurotransmitters: • Chemical messengers that cross the synaptic gaps between neurons • Bind to receptor sites on receiving neurons • Influences whether receiving neuron will generate a neural impulse • Endorphins: • “Morphine-within” • Natural opiate-like neurotransmitter linked to pain control and pleasure • Reuptake: • A neurotransmitter’s reabsorption by the sending neuron

  6. Neural Communication What are some activities that may cause the body to produceendorphins?

  7. Neural Communication

  8. Neurotransmitters and their Functions

  9. Neurotransmitter Pathways

  10. Neurotransmitter Skits • Directions: • In groups of 4-5 students, create a skit using any 4-5 of the characters below, to demonstrate the functions of the Neurotransmittersthat you have learned about in this unit. • Design a scenario and write a script(minimum: 20 lines), in which the characters’ personalities and interactions with one another reflect the roles of the associated neurotransmitter. • Each group will be required to performtheir skits, and must submit one written scriptper group.

  11. Neurotransmitter Skits • Cast: • Alice Choline • Donna Dopamine • Sarah Tonin • Nora Pinephrine • Gabe Gaba • Gary Glutamate • Eric Endorphins • Other (The Brain, Prozac, etc.)

  12. Homework • Unit 3-A FRQ: • Unit 3-A Quiz: “The Neuron”
