Detailed Description

Example simulation illustrating the effect of delay connection.

The simulation sets up a single input neuron and connects it to a single output neuron via a SparseConnection (which only has the axonal delay from IFGroup) and via a DelayConnection which has both the axonal delay plus an added 10ms dendritic delay. The latter connection is GABAergic to make it easily differntiable in the membrane trace.
