Neu 311L Final Questions with Answers (100% Correct
Answers)
The Nernst equation predicts that Answer: as extracellular potassium
increases, RMP decreases
For a Pearson correlation, you should report these values Answer: p,r,n
Which is the correct order of events for blue light-induced EPSP's in
muscle 6 of a ChR: Answer: ChRs expressed in the glutamate neurons
open sodium flows into those glutamate neurons, calcium enters those
glutamate neurons, glutamate is released into the synapse, glutamate
binds to AMPA receptors expressed in muscle 6, sodium enters the
muscle cell.

This illustration depicts which side of the membrane as the intracellular
side (at rest)? Answer: the right side because the left side is positive
relative to the right side and shows more potassium on the right side
relative to the left side
In the graph if the membrane was only permeable to sodium, what
would the potential be if calculated by the Nernst equation? Answer:
above 0, positive
