The paper introduces a method to profile miRNA expression in specific cell types and compartments in the mouse brain using transgenic mice and validates its effectiveness through bioinformatic analysis.

The paper introduces AGO-APP to isolate active miRNAs from Drosophila neural cells, identifies a miRNA module controlling neuroblast to neuron transition, and shows their cooperative function.

The paper identifies Vax1's role in regulating neuronal subtype production in the olfactory bulb by repressing Pax6 via miR-7, influencing positional identity of neural stem cells.

This study uses 2-photon imaging to show that neuronal integration in the adult olfactory bulb occurs without cell loss and without a critical period, challenging the turnover model.
