Review for NeurIPS paper: Attention-Gated Brain Propagation: How the brain can implement reward-based error backpropagation

The reviewers agreed that this paper provides an important contribution to the biological learning literature, and agreed that it should be accepted. However, the reviewers were also in agreement that the authors must do the following for the camera-ready version of the paper: 1) Provide greater clarity that this is an extension of AGREL and does not involve any changes to the core AGREL algorithm, but rather, a means of gating the attention signals sent back through multiple layers.
