Presentation Transcript

  1. Neurons, Neurotransmitters, and Neurotransmission Unit 2

  2. Structure and Function of a Neuron

  3. Neuron Analogy Review Dendrite Axon Myelin Sheath Terminal buttons Synapse Resting potential All-or-none Law Like a tree. Also, each branch is a telephone wire that carries incoming messages to you. Like a gun. Fires completely or not at all. Like the insulation that covers electrical wires. Like a silicon chip in a computer that receives and transmits information between input and output devices as well as between other chips. Like an electrical cable that carries information. Like a battery. Stable until electrical charge stimulates it. Like the nozzle at the end of a hose, from which water is squirted. Like a railroad junction, where tow trains may meet.

  4. Neural Communication

  5. Firing a Neuron is like Flushing a Toilet

  6. The Synapse: Communication between Neurons

  7. Reaction Time of Neural Transmission and Mental Processes

  8. Serotonin Neurotransmitters Norepinephrine S-N-A-G-G-E-D Create a mnemonic device p.57 Acetylcholine (ACh) GABA Glutamate Endorphins Dopamine

  16. Agonists- molecules that excite / mimic neurotransmitters • Cocaine -- dopamine • LSD and Ecstasy -- serotonin • Morphine, oxycodone, heroin (opiates) – endorphins • Antagonists- molecules that inhibit / block neurotransmitters • Botulin causes paralysis by blocking Ach release Agonist versus Antagonist Drugs
