The Adjustment of Anterior Forebrain Pathway (AFP) to Birdsong Is Phased during Song Learning and Maintenance

Figure 10

Synaptic conductance matrix and its adjustment caused by AFP during song learning. (a) and (b) show synaptic conductance matrices before and after training with color depth representing conductance intensity. (c) and (d) show adjustment rate and adjustment amount of synaptic conductance between each HVC_RA neuron and each RA neuron after training. In each subgraph, the square in () represents the synaptic conductance from HVC_i to RA_j with its color indicating the value.
