Sensory Stimulation Triggers Spindles During Sleep Stage 2

Sleep 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 ...

Microsleeps are Associated with Stage-2 Sleep Spindles from Hippocampal-Temporal Network

Behavioral microsleeps are associated with complete disruption of responsiveness for [Formula: see text][Formula: see text]s to 15[Formula: see text]s. They can result in injury or death, especially in transport and military sectors. In this study, EEGs were obtained from five nonsleep-deprived healthy male subjects performing a 1[Formula: see text]h 2D tracking task. Microsleeps were detected ...

Characterization of Sleep Spindles

Local Field Potential (LFP) measurements from sleep data is important in Neurological studies because experiments have shown a correlation between sleep and memory consolidation [1]. The most prominent of the coherent signals within LFP sleep data are spindles, which occur most often when a person is dozing off, durring Stage 2 of Non-Rapid-Eye-Movement (NREM) sleep [2]. Determining the specifi...

Stimulation of muscle spindles

Magnetoencephalography demonstrates multiple asynchronous generators during human sleep spindles.

Sleep spindles are approximately 1 s bursts of 10-16 Hz activity that occur during stage 2 sleep. Spindles are highly synchronous across the cortex and thalamus in animals, and across the scalp in humans, implying correspondingly widespread and synchronized cortical generators. However, prior studies have noted occasional dissociations of the magnetoencephalogram (MEG) from the EEG during spind...
