These are some experiments to try using the Tritonia Tutorial.  In each
case, you should satisfy yourself that you understand what is happening in
the various plots.

What effect do you expect the IA current in the VSI to have on the timing of
the bursts?  Test your hypothesis by setting the maximum conductance for
this channel to zero.

What effect do the time constants for the excitatory synapse from C2 to
VSI have upon the timing of the bursts?  What about those for the connection
from DSI to C2?

What effect does the decay rate of the Na-ramp channel (default value 15
sec) have on the number of bursts produced?

Explore the effect of the VSI-VSI recurrent excitatory connection on the
number of bursts by adjusting either the synaptic strength or the weight
of this connection.

Experiments have shown that tonic depolarization of the C2 cell by constant
current injection will result in the generation of a swim pattern (Getting
1977).  See if you can produce this behavior in the simulation, as well.
