Question 1

Describe the changing of the resting potential by a weak stimulus

Answer 1

Threshold is needed to be reached to produce pulses along the axon (without attenuation)

Upon stimulation of the axon analog circuit, there is a change in potential difference across the capacitors.

The further from the stimulus, the slower the changes

Question 2

Give the Equation to calculate the difference between the final and resting potential.

Answer 2

V(x) = V_de^-x/λ

• x = Distance from stimulus*
• λ = Space parameter*
