3) Where is TTX obtained from?
4) What was the effect of Lidocaine?
5) Relate 4 above to Lidocaine's clinical use
Activity 5: Measuring Refractory Periods of Neurons:
this simulation you will gradually decrease the time between successive stimuli until:
d. A stronger stimulus is required to generate a 2nd AP (relative refractory period) of
b. A second AP cannot be produced at all (absolute refractory period).
Use your data from Chart 5 to answer the questions below:
1) What interval between stimuli initially prevented a second AP?
2) Was this the relative or absolute refractory period?
3) What was the minimum interval for relative refractory period (hint: minimum interval where you could still
generate a second AP with a stronger stimulus?
4) What interval completely prevented a second AP?
5) Is this relative or absolute RP?
ME
Activity 6: The "Language" of the nervous system: Frequency of Aps.
Use your data from Chart 6 to answer the questions below:
1) What is the effect of increasing stimulus intensity on AP frequency?
प्र (
2) What are 2 ways we can overcome the relative refractory period to produce a second AP2
Actvity 7: AP Conduction Velocity
Use your data from Chart 7 to answer the questions below:
1) Which fiber had the fastest velocity?
2) What 2 factors influence conduction velocity?
