Interconnectivity

class cell_connection

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.

using cell_connection_endpoint = cell_member_type

Connection end-points are represented by pairs (cell index, source/target index on cell).

cell_connection_endpoint source

Source end point.

cell_connection_endpoint dest

Destination end point.

float weight

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).

float delay

Delay of the connection (milliseconds).

class gap_junction_connection

Describes a gap junction between two gap junction sites. Gap junction sites are represented by :cpp:type:cell_member_type.

cell_member_type local

gap junction site: one half of the gap junction connection.

cell_member_type peer

gap junction site: other half of the gap junction connection.

float ggap

gap junction conductance in μS.
