All about synapses and connections in NEST

Connections between nodes define possible channels for interactions between them. A connection between two nodes is established, using the command Connect.

Each connection has two basic parameters, weight and delay. The weight determines the strength of the connection, the delay determines how long an event needs to travel from the sending to the receiving node. The delay must be a positive number greater or equal to the simulation stepsize and is given in ms.
