Infrequently, domains of identical or near-identical sequence recurred in blocks.
Sequences recur from piece to piece: a solo once set to Stravinsky's The Rite of Spring is reworked to David Bowie's Aladdin Sane.
However, some of the sequences recurred on subsequent trials, allowing us to assess implicit learning of the repeated sequence (Hebb effect).
Such place cell firing sequences recur during rapid eye movement sleep and slow wave sleep, and this process is thought to be involved in memory consolidation (Skaggs & McNaughton, 1996; Nadasdy et al., 1999; Louie & Wilson, 2001; Lee & Wilson, 2002).
In a dream sequence that recurs throughout the 1987 movie "La Bamba," two planes fly over a schoolyard where youths play basketball in slow motion.
Considering the above findings, one reason why the winner of the previous intermittent presentation sequence often recurs during the current intermittent presentation sequence could be that it has enjoyed much dominance in the past.
Other analyses have compared the repetition necessary to complete a difficult sequence to recurring dreams, in which one might be trying to work through trauma.
But the same DNA sequence could recur elsewhere in the genome, leading the molecular scissors to cut in the wrong place.
Such behavior, which is generated within the cortex, may provide a framework for neural computations [4], and could also coordinate some sleep rhythms into a coherent rhythmic sequence of recurring cortical and thalamocortical activities [3], [5], [6].
If the same sequence indeed recurred during spontaneous activity, these correlations would be higher.
