To Determine the Length Constant, or Space Constant, You Can

question 13

Multiple Choice

To determine the length constant, or space constant, you can inject current (without activating an action potential) and plot (Vr is the resting membrane potential; electrotonus is the steady-state voltage)

• A) Ln (V - V_r) vs x during conditions of electrotonus
• B) Ln (V - V_r) vs t during conditions of electrotonus
• C) Ln (V - V_r) vs t during the rise phase or decline phase of electrotonus
• D) Ln (V - V_r) vs t only during the decline phase of electrotonus
• E) Ln (V - V_r) vs t only during the rise phase of electrotonus
