UA mechanical properties and neural control are altered, imposing a mechanical load on inspiration. UA collapse does not occur during wakefulness, hence arousal-dependent compensation. Experimental inspiratory loading in normal subjects elicits respiratory-related cortical activity during wakefulness. The objective of this study is to test whether awake OSAS patients would exhibit a similar cortical activity. Whether or not such cortical compensatory mechanisms have cognitive consequences would be also analyze.",[73],"Obstructive Sleep Apnea Syndrome","2025-11-28",{"date":76,"type":77},"2025-12-02","ACTUAL",{"date":79,"type":77},"2023-03-02",{"date":81,"type":67},"2027-07-02",{"name":5,"class":6},1]
