This valuable study elucidates the essential role of the chromatin regulator KDM6B in the establishment and maintenance of neural stem cells (NSCs) in the mouse hippocampus. While the evidence supporting the authors' claims is largely solid, a more comprehensive investigation into the cellular and molecular events underlying the loss of hippocampal NSCs would have further strengthened the study. Nonetheless, the findings will be of interest to biologists studying neural development and NSCs.

eLife assessment

This valuable study provides evidence that during learning of a simple detection task, the change in the rate of spike bursts is a signal that is distinct from the change in firing rate, and suggests that the change in bursting is more correlated with learning than other measures of change in activity. However, the evidence for the claim that bursting contributes to learning and attention is currently incomplete, because the authors did not take into account the potentially differential effects of learning-related changes in movement on bursting compared to non-burst spike events, and there is no meaningful way to measure attention in their task. Also, the study used an artificial microstimulation as the stimulus, which limits the generalization of these results to normal sensory-motor learning.
