Function Documentation

connect_synaptic_element()

virtual void nest::Node::connect_synaptic_element ( std::string  , int    )

inlinevirtual

Parameters

type	std::string, name of the synaptic element to connect
n	int number of new connections of the given type

Reimplemented in nest::StructuralPlasticityNode.

decay_synaptic_elements_vacant()
