WebJun 13, 2024 · Spindle duration and frequency also correlates with intelligence (Bódizs et al. 2014). As learning involves both long-term potentiation (LTP) and long-term depression (LTD) of synapses, packets of synchronized neural activity such as up-states or cycles of sleep spindles make these oscillations an ideal candidate for ‘burning in’ new memories. WebMar 22, 2024 · Sleep has well defined brain states which are called Wake, Stage 1, Stage 2, Stage 3, Stage 4 and rapid-eye-movement (REM) sleep. In the more recent terminology Stage 3 and Stage 4 are combined as one stage and called slow-wave sleep (SWS). A more coarse classification consists of Wake, REM and non-REM, where non-REM combines Stage 1, … WebSleep spindles are bursts of rhythmic 10-15 Hz activity, lasting ∼0.5-2 s, that occur during Stage 2 sleep.

Sleep Spindles – As a Biomarker of Brain Function and Plasticity

WebSleep spindles are high-frequency oscillatory activity generated by interplay of the thalamic reticular nucleus and other thalamic nuclei during stage 2 NREM sleep. The functional role of sleep spindles remains unclear, although research strongly supports that sleep spindles actively mediate declarative memory consolidation. Webrange of sleep spindles has further been divided by researchers into slow spindles (11–13.5 Hz) and fast spindles (13.6–16 Hz). 6. Although . it is generally accepted and shown in different studies that sleep spindles occur primarily in stage 2 sleep, some studies have also found that sleep spindles are also present in rapid eye movement
