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?

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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
