Document Summary
Explain what is meant by a silent synapse and how its presence might result in a postsynaptic explanation of an increase in quantal content. a. Silent synapses make it look like there"s an increase in quantal content that is only attributed to the presynapse. However, a silent synapse is when the presynaptic cell is affected by the activity of the postsynaptic cell. i. For example, it the postsynaptic cell is strongly depolarized, the depolarization will kick off mg2+ from nmda receptor and neighboring nmda receptors: depolarization of postsynaptic membrane opening of voltage gated. Ca2+ channels increase of intracellular ca2+ camkii activation removal of mg2+ from nmda receptors founds on intracellular vesicles removal of mg2+ from nmda receptors on the membrane of the postsynaptic cell. What types of cellular and molecular changes occur during late ltp: multiple spaced trials and block protein synthesis b.
