eLife Assessment
This is a valuable analysis of STORM data that characterizes the clustering of active zones in retinogeniculate terminals across ages and in the absence of retinal waves. The design makes it possible to relate fixed time point structural data to a known outcome of activity-dependent remodeling. The latest revision has tempered the causal claims made in previous versions. The result provides solid structural support for the hypotheses regarding how activity influences the clustering of these synapses.
