The authors regret to report an error in the second line of Fig. 5d. In Fig. 5d, the formula for the eligibility trace on the synapse from HVC to area X MSNs (EHVC-X) was incorrect. The eligibility trace is initiated by the joint activation of inputs from LMAN (L) and from HVC (H). The corrected formula is provided in the revised figure below.
