Homework Answers
1. Select the last two sweeps recorded from the Display Sweeps list. Superimpose these sweeps on each other by checking the Stacked box.
2.Select Title and T2-T1 from the Table Functions list.
3. Click the 2-Cursor icon in the LabScribe toolbar. Drag the cursors to the peaks of the two compound action potentials. The value for T2-T1 in the table at the top of the ScopeView window is the time it took the action potential to travel the distance between the two positions of the negative recording electrodes.
4. Read off the T2-T1 value- 4.5m/s.
5. Calculate the conduction velocity (in m/s). Distance between the electrodes/4.5m/s.

4. This figure (part a) shows a segment of the ventral nerve cord of the crayfish (which is analogous to our spinal cord). The lateral giant nerve fiber runs down this nerve cord and passes a signal to the motor giant neuron, which triggers muscle contraction in a tail flip escape response. Look at the neural recording that is shown (part b). It shows the presynaptic action potential of the lateral giant neuron and the postsynaptic action potential of the...

Q3. (1 mark) If an axon had a conduction velocity of 115 m/sec what two structural features would it have if it was viewed using a transmission electron microscope? Q4. (1 mark) If an axon had a conduction velocity of 115 m/s how long would it take for an action potential to travel along this axon if it was 1520 mm long? Show your calculation.
