1
Q

Rising phase

A

Characterized by a rapid depolarization of the membrane.

2
Q

Overshoot

A

The part of the action potential where the inside of the neuron is positively charged with respect to the outside.

3
Q

Falling phase

A

Rapid repolarization until the membrane is more negative than the resting potential.

4
Q

Undershoot

A

(After-hyperpolarization) Gradual restoration of the resting potential.

5
Q

the net movement of ions across the membrane is…

A

…an electrical current (I).

6
Q

What is g?

A

Conductance.

7
Q

Equation for current.

A

I = g(V-E)

- V-E is driving force

8
Q

Voltage Clamp

A

Clamps the membrane potential of axon at any value.
