|1||Given a change in a parameter that influences net driving force, equilibrium potential, or resting membrane potential, predict how this influences net driving force, equilibrium potential, resting membrane potential, or current across the membrane.||A drug is applied to a neuron that temporarily blocks a substantial portion (~65%) of the resting K+ ion channels in the neuron's membrane preventing any ions from moving through these channels. |
|2||Predict the type of ion channel in a given functional region of a neuron for a novel scenario.||What type of gated ion channel would you most likely expect to find at the input region of the motor neuron (arrow) in the figure above?||Considering the 4 types of gating stimuli, which type of gated ion channel would you expect to be characteristic of the input region of this sensory afferent?|
|3||Calculate time and length constants, input resistance and input capacitance from graphical data (for ex., I–V data) or numerical values||Calculate the input resistance for this neuron, based on these I–V data.|
Calculate the conductance(s) for this ion channel (based on the I–V data shown).
|Calculate the conductance(s) for this ion channel (based on the I–V data shown).|
|4||Differentiate between electrical, chemical, and net driving forces, and, given a set of data, predict the direction or relative magnitude of the current flow (net or ionic) due to these forces and its effect on the membrane potential.||If the membrane potential is −60 mV and the equilibrium potential for chloride is −80 mV in a typical cell, what are the directions of the electrical, chemical, and net driving forces acting on chloride?||What are the directions of the chemical, electrical, and net driving forces acting on K+ in a typical neuron when the membrane potential is 55 mV?|
