Compare and contrast graded potentials and action potentials. What are the functions of graded potentials if they do not result in an action potential? comments : please give me the best answer to increased my knowledge so i will have a better understanding of the question asked
Based on the graph, how soon could another action potential be easily initiated (at the end of the relative refractory period) after the first stimulus? (Base your answer to this question on the graph below depicting an action potential.) less than 0.5 msec 1 msec 2 msec 3 msec 4 msec
In the laboratory, researchers can apply an electrical stimulus at any point along the axon, making action potentials travel in both directions from the point of stimulation. An action potential moving in the usual direction, away from the axon hillock, is said to be traveling in the orthodromic direction. An action potential traveling toward the axon hillock is traveling in the antidromic direction. If we started an orthodromic action potential at the axon hillock and an antidromic action potential at the opposite end of the axon, what would happen when they met at the center? Why?
Once an EPSP is produced in a dendrite, how does it stimulate the production of an action potential at the axon hillock?
