REPRODUCING FIGURE 6B.
## REPRODUCING FIGURE 6B

- To reproduce Fig. 6B use GUI (Best fit model). Hit RUN button. Wait
until the model finishes three sets of simulations (BLACK, RED, and
GREEN).

BLACK = Control with all currents intact.
RED = Block of sodium current with TTX.
GREEN = Block of A-type current with 4-AP.

- Graph[0] plots the AP waveforms in the soma.

- Graph[1] plots the AP waveforms in the basal dendrite (indicated by
asterisk in Figure 6A).

(1)During the simulation Graph[2] is a space plot of AP waveforms
along all basal dendrites considered in the model (BLACK motion).

(2)At the end of the entire set of experiments (CTR, TTX and 4-AP)
Graph[2] plots peak AP amplitudes along all basal dendrites considered
in the model (multiple locations). Each line corresponds to one basal
dendrite. Each dendrite is analyzed in three conditions (CONTROL, TTX
and 4-AP) and therefore each dendrite is represented with three lines
at the end of simulations (BLACK, RED and GREEN).

- Note: Duration is set to 15 ms. This can be changed in a hoc file by
changing tstop variable.
