The learning dynamics of the CN to AN feedback. This signal is mediated by a layer of feedback neuron selective to CN and external input activity. The synapses connecting the feedback neurons to the AN are modified with the same learning dynamics as the one used for the AN synapses (see Fusi et al. (2007) and the description of the AN dynamics in the Methods).
