Experiment 2
Pulse Propagation
Purpose: The objective is to estimate the speed of a pulse in a given dendritic tube.
A dendritic tube can be modeled as follows.
x1 1 2 seg1
x2 2 3 seg1
x3 3 4 seg1
x4 4 5 seg1
x5 5 6 seg1
x6 6 7 seg1
x7 7 8 seg1
x8 8 9 seg1
x9 9 10 seg1
x10 10 11 seg1
Simulation results are in Fig. A.12 .
• What is the speed of propagation in cm/s?
• Is there a back propagation from the end? How can you know?
• How much must segment capacitance be increased to increase delay (slow
down) by 20 %?
