Use what you know about the physiology of neurons to
answer the following questions. Treat questions a - c as unrelated
to each other.
a. Imagine that a toxin creates pores that are permeable
to Ca2+. Describe its immediate effect on the resting potential of
the neuron: identify which ions diffuse across the membrane, which
direction they diffuse (and why), and whether this brings the
neuron closer to or further from threshold
potential.
b. Imagine that a toxin makes K+ leak channels more
permeable to K+ ions. Describe its immediate effect on the resting
potential: identify which ions diffuse across the membrane,
which direction they diffuse (and why), and whether this
depolarizes or hyperpolarizes the neuron.
