Down-regulation of insular cortex responses to dyspnea and pain in asthma.
RATIONALE: Dyspnea is the impairing cardinal symptom of asthma but its accurate perception is also crucial for timely initiation of treatment. However, the underlying brain mechanisms of perceived dyspnea in patients with asthma are unknown. OBJECTIVES: To study brain mechanisms of dyspnea in asthma. METHODS: By using functional magnetic resonance imaging we compared the neuronal responses to experimentally induced dyspnea in patients with asthma and healthy controls. These brain activations...Expand abstract
