Mom's meals shape baby's sense of smell

Biologists at Colorado University have based their findings on an experiment on rodents. They claim to have found the reason and how it affects the physical development of the smelling system.

Exposure to certain odours triggers glomeruli — spherical structures in the olfactory bulb that relay smell messages from nasal cavity to brain — to grow rather than others. And among the most powerful odours that a foetus would experience is that of its own mother.
