Power spectral analysis of EEG activity during sleep in cigarette smokers.

abstract：BACKGROUND:National spirometric surveillance data in the United States were last collected during 1988-1994. The objective of this study was to provide current estimates for obstructive and restrictive impairment of lung function and to examine changes since 1988-1994. METHODS:We used data from 14,360 participants age...
