TA: Anna Gruzman Section 3 E-mail: agruzman@ucsd.edu 1/24/10 1. What would cause an increase in the velocity of conduction for an action potential? 2. Write out the steps for neurotransmitter release at the synapse of a cell starting from the depolarization at the axon terminal. http://www.sumanasinc.com/webcontent/animations/content/synaptictransmission.html 3. EPSP: IPSP: Can EPSP or IPSP cause the postsynaptic neuron to produce an action potential? Does this always happen? 4. What do acetylcholinestrase, curare, and botulin toxixn all have in common? What are the similarities and differences in the mechanisms that allow them to achieve this?

Unformatted text preview: ionotropic receptors and the brain and the spinal chord have ionotropic inhibitor receptors. List the respective properties of each of the above receptors. Include the neurotransmitter and the ion(s) responsible for the excitation or inhibition: Receptor: Neurotransmitter: Hippocampus: Ionic Selectivity of the channel: EPSP or IPSP: i. ii. Receptor: Neurotransmitter: Brain: Ionic Selectivity of the channel: EPSP or IPSP: Receptor: Neurotransmitter: Spinal Chord: Ionic Selectivity of the channel: EPSP or IPSP: 7. Write out the steps of Long Term Potentiation starting with Glutamate binding to AMPA and NMDA Receptors. ( Refer to figure 8-32 in your book) 8.
