Describes a connection between two cells: a pre-synaptic source and a post-synaptic destination. The source is typically a threshold detector on a cell or a spike source. The destination is a synapse on the post-synaptic cell.
Source end point, represented by a
cell_global_label_typewhich packages a cell gid, label of a group of sources on the cell, and source selection policy.
Destination end point on the cell, represented by a
cell_local_label_typewhich packages a label of a group of targets on the cell and a selection policy. The target cell’s gid is implicitly known.
The weight delivered to the target synapse. The weight is dimensionless, and its interpretation is specific to the synapse type of the target. For example, the expsyn synapse interprets it as a conductance with units μS (micro-Siemens).
Delay of the connection (milliseconds).

Describes a gap junction between two gap junction sites. The
localsite does not include the gid of a cell, this is because a
gap_junction_connectionis bound to the local cell which means that the gid is implicitly known.
A bidirectional gap-junction between two cells
gap_junction_connectionobjects to be constructed: one where
peersite; and another where
ggapis equal in both connections, a symmetric gap-junction is formed, other wise the gap-junction is asymmetric.
Peer gap junction site, represented by a
cell_local_label_typewhich packages a cell gid, a label of a group of gap junction sites on the cell, and a site selection policy.
Local gap junction site on the cell, represented by a
cell_local_label_typewhich packages a label of a group of gap junction sites on the cell and a selection policy. The gid of the local site’s cell is implicitly known.
