Creators Suetsugi Masatomo

The distinct theta rhythm in the frontal midline area during performance of mental tasks has been called Fmθ. We have reported that some characteristics of theta rhythm during sleep are similar to those of Fmθ during mental tasks. In the present study, polysomnographic examinations were undertaken to clarify the relationship between theta rhythm during sleep and sleep spindle. The subjects consisted of two groups of 8 male students each, one of which showed Fmθ (Fmθ appearance group), and the other of which failed to show Fmθ (non-Fmθ appearance group) in 3 consecutive days of the pilot study. Polysomnograms were recorded for 4 consecutive nights from each subject. Theta rhythm during sleep appeared even in the non-appearance group
