Topic: olfactory experience

The interplay between olfaction and higher cognitive processing has been documented in the adult brain, yet its development is poorly understood. In mice, shortly after birth, endogenous and stimulus-evoked activity in the olfactory bulb (OB) boosts the oscillatory entrainment of the downstream lateral entorhinal cortex (LEC) and hippocampus (HP). The tight anatomical connections between olfactory system and higher-order neuronal circuits might implicate the functional impact of olfactory outputs on cognitive functions along brain development. However, it is unclear whether early OB activity h
