Topic: cognitive processing

Cognitive processing requires directed interactions between several brain areas of the limbic system, such as the hippocampus (HP) and lateral entorhinal cortex (LEC). They are modulated by multiple sensory systems. During development, the olfactory system might have a particular impact on these areas in mice that at birth are blind, deaf, do not whisker and have poor motor abilities. We previously showed that neonatal olfactory activation boosts the oscillatory entrainment of LEC via mono-and polysynaptic projections from the olfactory bulb (OB). However, the long-lasting impact of olfactory
