abstract：:The respiratory-related evoked potential (RREP) is the electroencephalographic response to brief inspiratory occlusion. The P3 component of the response reflects the active cognitive processing of stimulus information. This study investigated the RREP in 16 subjects with asthma and 16 control subjects.
