MVC - Synaptic Integration

Question 1

What is the language of neurons?

Answer 1

Electrical signalling

• Connectivity (modality)
• Patterns of activity (intensity)

Chemical signalling

Question 2

What results in an electrical current?

Answer 2

When allowed to move between compartments, the flow of electrical ion charges down their electrochemical gradient produces an electrical current

Question 3

What is resistance?

Answer 3

The restriction to ion flow

Question 4

What is Capacitance?

Answer 4

The ability of a system to store an electric charge

Question 5

What is Ohms Law?

Answer 5

The electrical circuit will consist of three related electrical variables called: Voltage, ( V, in volts ), Current, ( I, in amperes ) and Resistance, (R, in ohms Ω ) or conductance (G, in siemens)

V = IR

Question 6

How does the voltage effect of a membrane current change with distance from the injection site?

Answer 6

Voltage effect decreases with distance

Question 7

Why does the voltage effect of a membrane current take time?

Answer 7

Due to membrane capacitance

Question 8

How does membrane potential differences arise?

Answer 8

From the separation of ions inside/outside cell

Question 9

What was used to determine the ionic basis of the action potential?

Answer 9

Voltage Clamps

Question 10

Rewatch recording for sure
