2. Long-term Potentiation is a process that strengthens the transmission of a single synapse in a circuit. This is achieved when pre-synaptic cells and post-synaptic cells fire action potentials at the same time. Usually multiple pre-synaptic cells synapse onto one post-synaptic cell, increasing the probability of inducing an action potential in the postsynaptic cell. b. If you were to use an antagonist that selectively blocked NMDA receptors, what would happen to LTP? Draw the voltage response shortly after LTP conditioning. Explain your answer. (Assume the antagonist was present before and during LTP conditioning, but you remove it before performing the experiment).

Which of the following is a result of long-term potentiation? The set of receptors on the presynaptic membrane change, resulting in a decrease in the size of the postsynaptic potentials at the synapse. As a result of summation, new synapses form on neurons most involved in storing a memory. The number of types and the relative amounts of neurotransmitters greatly increase at a synapse involved in memory formation. The set of receptors on the postsynaptic membrane change, resulting in a stable increase in the size of the postsynaptic potentials at the synapse.

6. What is the long-term potentiation? What is the role of Ca2+ in long-term potentiation? Review the following figure and explain in your own language. (10 Pts) presynaptic cell glutamate released by activated presynaptic nerve terminal opens AMPA-receptor channels, allowing Na+ influx that depolarizes the postsynaptic membrane depolarization removes Mg2+ block from NMDA-receptor channel, which (with glutamate bound) allows Ca2+ to enter the postsynaptic cell glutamate polarized membrane postsynaptic cell Mg2+ AMPA receptor NMDA receptor depolarized membrane increased Ca2+ in the cytosol induces postsynaptic cell to insert new AMPA receptors in the plasma membrane, increasing the cell's sensitivity to glutamate Figure 11-44 Molecular Biology of the Cell 6e (© Garland Science 2015)
