主　　题：Near-infrared spectroscopy hemoglobin brain smoking 

摘      要：We used a mobile wireless near-infrared sensor for the noninvasive recording of cerebral hemoglobin concentration changes during cigarette *** measurement included 5 min of rest,5 min of smoking imitation,and 5 min of actual *** observed significant effects of the tobacco smoking on temporal changes in the human brain at time scales ranging from 200 ms to about 1 *** most reproducible effects were an increase of the heartbeat rate and a decrease in the heartbeat power spectral density during *** but highly individual changes due to smoking were observed in temporal patterns of hemodynamic fluctuations in 5–50 s time *** have also found statistically significant slow increases in both oxy-and deoxy-hemoglobin concentrations during smoking.
