In the Panacea Project many kundalini yoga breathing exercises are used in a trauma-sensitive way. Alternate nostril breathing is a key part of the course. A study was done to test the effect of alternate nostril breathing on the P3 (P300) brain wave. This wave is an event related potential (ERP) component induced by the decision making process. It is not linked to any physical stimulus but a persons actual reaction to stimulus. 

The below study measured alternate nostril breathing against a normal breath awareness class for auditory evoked potentials.

Results showed there was a significant increase in the P300 amplitudes at the frontal, vertex and parietal parts of the brains with a decrease in peak latency at the frontal area. The study of the breath awareness class only brought about changes in the vertex. What does this mean?

In short, we can confidently say that alternate nostril breathing positively impacts the cognitive processes needed for sustained attention much better than a simple breath awareness class.
