Electroencephalogram characteristics of autonomic arousals during sleep in healthy men

2006 Clinical Neurophysiology  
We evaluated the temporal relation between heart rate (HR) changes, an index of autonomic activation, and EEG in seven healthy subjects during sleep.  ...  Methods-We identified bouts of tachycardia-bradycardia and performed spectral analysis of EEG during these. We also identified cortical arousals by the appearance of EEG alpha activity.  ...  Despite these limitations, however, the data presented here do suggest that assessment of HR changes during sleep might be a useful tool in assessing arousals during sleep.  ...

Complexity of EEG (omega), a global measure reflecting degree of spatial synchronization, was computed for whole night recordings of sleep EEG of 10 healthy volunteers, 9 males and 1 female (age 21-53)  ...  In healthy subjects the complexity was higher over the right hemisphere during waking, and the difference shifted to higher complexity over the left hemisphere in slow wave sleep (F = 5.15, df1 = 4, df2  ...  These two measures assess the properties of EEG in traditional dimensions; they are multichannel analogs of Hjorth's descriptors of activity and mobility, respectively.  ...
