The description of a LIF cell is used to control the leaky integrate-and-fire dynamics:
Initial value of membrane potential.
Membrane potential decaying constant.
The morphology of a LIF cell is automatically modelled as a single compartment; each cell has one built-in source and one built-in target which need to be given labels when the cell is created. The labels are used to form connections to and from the cell. LIF cells do not support adding additional sources or targets to the description. They do not support gap junctions. They do not support adding density or point mechanisms.
