There are a lot of experiments that need to be done to distinguish between the nasal component and the non-nasal component of these breathing related signals.

The practice of cyclic hyperventilation, which involves exhaling and holding one's breath for certain periods of time, has been found to potentially improve cognitive function by mimicking a state of heightened alertness.

Summary
The practice of cyclic hyperventilation, which involves exhaling and holding one's breath for certain periods of time, has been found to potentially improve cognitive function by mimicking a state of heightened alertness. However, the extreme levels of hypoxia achieved in clinical settings cannot be fully replicated through this practice.

Researchers have proposed that nasal breathing activates certain brain centers that mouth breathing does not, which might produce different levels of alertness or calmness, but also enhance memory and recall.

Summary
Researchers have proposed that nasal breathing activates certain brain centers that mouth breathing does not, which might produce different levels of alertness or calmness, but also enhance memory and recall. A study comparing nasal and mouth breathing showed that the hippocampus, an area involved in memory formation, was more active, resulting in better recall when people learned information while nasal breathing.
