The paper investigates the developmental emergence of internal and external hippocampal representations in mice, finding that internal sequences appear at postnatal day 24, following cue-based representations.

The paper introduces Track2p, a cell-tracking method for longitudinal analysis of neuronal activity in developing mouse brains, revealing a developmental transition in activity statistics.

The paper identifies intraglomerular neuronal ensembles in the olfactory bulb that encode both odor identity and concentration.

The paper shows that sensory deprivation causes GABAergic interneurons to die while dopaminergic neurons adapt by reducing tyrosine hydroxylase expression in mice.

The paper investigates how intrinsic neuronal activity during migration affects the recruitment of specific interneuron subtypes in the postnatal mouse olfactory bulb, finding that activity is critical for granule cell precursor migration and positioning but not for periglomerular neuron precursors.

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.
