|
There are two varieties of channels that control the voltage within a neuron. What are they?
|
Potassium (K) and Sodium (Na)
|
|
|
Which of the two channels are persistent? What does this mean?
|
Potassium is Persistent.
This means there is only one closed state. |
|
|
How many sub-gates are there in a Potassium gate?
|
4
|
|
|
How does this affect the conductance of the gate?
|
gK = ¬(gK) * n^4
where n is Pr(sub-gate being open) |
|
|
What is the equation that governs the flow of current through the potassium gate?
|
IK = gK * (V - EK)
this is reversed from the Integrate and Fire model as the concentration of K within the cell is greater than the concentration outside. EK is usually -70mV but can be determined by the Nernst Equation |
