You are studying the function of a newly-identified neuron in the auditory system of the barn owl. To help plan
You are studying the function of a newly-identified neuron in the auditory system of the barn owl. To help plan your experiments, your colleague proposes a number of hypotheses/predictions. Given what you know about action potential generation and propagation, identify which of these statements is/are TRUE. Select ALL that are TRUE.Question 1 options:a. Increasing the number of “leak” (or background) potassium channels in this neuron’s axon will decrease the membrane resistance and thus increase the length constant of this axon.b. If the action potentials in this neuron are generated by a classic mechanism involving voltage-dependent Na and K channels, then increasing the intracellular concentration of Na should have no effect on the action potential thresholdc. If the threshold for action potential generation is increased by a specific drug, the speed of action potential propagation along this axon should be slower.d. If myelination of this axon is degraded, then the length constant of this neuron should be decreased (shortened).e. Depending on the specific ion channels that are expressed by this neuron, it may be possible to generate an action potential with a hyperpolarizing current stimulusf. If you apply a drug that decreases the relative refractory period, then this neuron should be able to generate and propagate action potentials at higher frequencies.
