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.

WebJul 13, 2024 · Abstract. Sleep is pivotal for memory consolidation. According to two-stage accounts, memory traces are gradually translocated from hippocampus to neocortex during non-rapid-eye-movement (NREM) sleep. Mechanistically, this information transfer is thought to rely on interactions between thalamocortical spindles and hippocampal ripples.
