Author response: Dual pathway architecture in songbirds enables robust sensorimotor learning

Year: 2026

Type: peer-review

Abstract: This study modeled vocal learning in zebra finches with a network of three components: a pathway with delayed/slow Hebbian learning that mimics the HVC-RA projection, a pathway with reinforcement learning that mimics the HVC-BG-RA projection, and a motor unit that mimics the syrinx and produces song output.The model convincingly reproduces key features of song learning and is a valuable step towards understanding how vocal learning is substantiated in the song system.The generic and simplified nature of the model limits its generalization to other forms of motor learning.Further examination of model assumptions and presentation of testable predictions would increase the impact of the study.
