Predict Question 2 If you apply a moderate stimulus to the sensory receptor a larger, depolarizing response will occur at R1, and an action potential will be generated at R2 and maybe at R4. a small, depolarizing response will ( ) occur at R1 and R2, and action potentials will occur at R3 and R4. action potentials will be generated at all four locations. small, depolarizing responses will occur at all four locations
