@evanrussek @NeilBurgess10 By showing the evolution of the representational basis for rollouts (MTL to PFC), we address the fundamental question of what systems consolidation is actually for. Not simply how representations change, but directly, how they contribute to subsequent flexible behaviour.

@evanrussek @NeilBurgess10 Using this method we can not only decode the contents of rollouts through the transition structure, but also, across trials within participants, decode the speed of sequential simulation. Faster reaction times are related to faster rollouts - i.e. thinking fast means acting fast.

@evanrussek @NeilBurgess10 Our straightforward MEG analysis, without free parameters, reveals sequential neural dynamics during decision-making. This method contrasts previous approaches in that it does not make a priori assumptions about the representational basis of rollouts (visual, linguistic, etc).

@evanrussek @NeilBurgess10 MB planning strongly related to RTs increasing with planning depth - the first direct evidence for MB rollouts. Critically, consolidation (1 week later) improves MB planning and enhances markers of step-by-step simulation in prefrontal cortex, indicating systems consolidation.

@evanrussek @NeilBurgess10 We created a novel high-powered behavioral task that distinguishes sequential MB from non-sequential SR planning, and new MEG analysis methods to clearly demonstrate MB rollouts centered in the MTL (evolving at up to 1 second per transition) during sequential planning.

@evanrussek @NeilBurgess10 Though widely hypothesised, scant evidence ties model-based (MB) planning to online sequential rollouts in the brain. Separately, little is known about how memory consolidation transforms neural representations to support adaptive planning via improved simulations of the future.

Hi everyone! If you are in London this week, do come by and check out our audio-visual installation about Replay. Working on this with @olivierhenaff at @FlorenceTrust made lockdowns bearable, and I'm very excited to share the results of that process.

"Computer simulations indicate the UK is in the early stages of its epidemic which is expected to rise sharply in four weeks and peak in 10 and 14 weeks' time.".

RT @YunzheNeuro: Super thrilled to share our years of work on human replay with the world, now out in Cell @CellCellPress, .
