Detailed Description

A device allows to receive reward traces from another process.

This device allows to receive a real-valued piecewise constant trace from another process using the MUSIC interprocess communication API. A typical application for this node is to receive a reward signal and communicate it to synapses that are trained using reward-modulated plasticity. The number of traces that are received by this device is given by the width of the MUSIC port. The received traces can be read out using the TracingNode::get_trace() member function.
