Sleep Spindles as an Electrographic Element: Description and Automatic Detection Methods
Sleep spindle is a peculiar oscillatory brain pattern which has been associated with a number of sleep (isolation from exteroceptive stimuli, memory consolidation) and individual characteristics (intellectual quotient). Oddly enough, the definition of a spindle is both incomplete and restrictive. In consequence, there is no consensus about how to detect spindles. Visual scoring is cumbersome an...
متن کاملShort Time Fourier Transform and Automatic Visual Scoring for the Detection of Sleep Spindles
Sleep spindles are the most interesting hallmark of stage 2 sleep EEG. Their accurate identification in a polysomnographic signal is essential for sleep professionals to help them mark Stage 2 sleep. Visual spindle scoring however is a tedious workload. In this paper two different approaches are used for the automatic detection of sleep spindles: Short Time Fourier Transform and Automatic Visua...
متن کاملSleep Spindles
The development of EEC sleep-spindles in prematurely-born and full-term infants was studied to test an hypothesized impact of experience (longer extrauterine existence) upon innate maturational factors (EEG development). The age of otiset of sleep spindles and achievement of mature spindle quality occurs approximately 4 weeks earlier in prematurely-born infants than in full-term infants. Sleep ...
متن کاملSleep Spindles Detection: a Mixed Method using STFT and WMSD
Sleep spindles are a hallmark of stage 2 sleep and are promising indicators of neurodegenerative disorders such as schizophrenia and dementia. In this paper two sleep spindle detectors are presented. The first is based on the Short Time Fourier Transform (STFT), the second is a novel algorithm and is based in the wave morphology of sleep spindles. Finally, a combination of the previous is propo...
متن کاملSleep Spindles – As a Biomarker of Brain Function and Plasticity
Spindles appear in the EEG as sinusoidal waves with frequency in the range 11 to 16 Hz. Together with K-complexes they are the hallmarks of NREM sleep and their appearance is taken as evidence of the onset of light sleep. Their specific distribution and exact frequency, changes in early and late sleep during the night. Sleep spindles are also known as “sigma waves” a term initially recommended ...
