Breathing! A simple way of taking air in and out by mouth or either nasal passage. It it is highly appreciable to breath by nose because of more efficient inhalation and ventilation that is facilitated by the nose. The nasal passage provide more filtered breathing because of inner nasal mucosa and ciliary lining.
But how about connection of nasal breathing to memory and cognition? Scientist at the North Western University, Illinois, United States have studied that nasal breathing tends be more efficient way rather than oral breathing because of breathtaking results it is showing.
The synchronization of brain waves is much more effective when you breath by your nose because of olfactory lobes in nasal passage. The nose provide a connection of oscillatory lobes of brain to the respiratory system. This connection leads its seat in hippocamous and amygdala. The hippocampus provide a platform for olfactory memory processes.
The oscillation in electrical signals and synchronization of brain waves created a rhythm that was broadly differentiated from the results obtained by mouth breathing.This research is opening new doors for future, where we may understand further more functions of brain and brain associated diseases.
