Air hunger engages the insular cortex; leaves open its role in clinical dyspnea and need for patient studies.
Does evoking severe 'air hunger' activate specific cerebral cortex structures in healthy subjects?
The perception of severe 'air hunger' activates the insular cortex, a limbic structure involved in homeostasis and survival behaviors.
