This was super fun! Thanks @alexandrapike.bsky.social for proposing and to @chloebrunskill.bsky.social and all speakers and attendees for making this day happen! 🥹

🥳

It is a great pleasure to share this new collaborative work on the Cognitive Neuroscience of Memory Representations with @fnim-lab.bsky.social @cvlneuro.bsky.social @psychologyuea.bsky.social

On the left: an illustration from Brooke's 1904 rendition of Goldilocks and the Three Bears, where Little bear discovers their favourite chair is broken 😲. On the right, a sketch of what a corresponding "situation model" might contain.

How might stories shed light on brain function? Check out this opinion piece by @alexbarnett.bsky.social and I about the DMN and "situation models" -- our understanding of the current "state of affairs" in a story (or even experience).

Was meant to be presenting at #BACN25 on Thursday. Unfortunately, COVID has decided otherwise. My poster will still make an appearance though. Even better? It’s presented by @aidanhorner.bsky.social instead! Go check it out on Thursday along with other lab posters on narratives, objects and schema.

Hi! Nice to virtually meet you! Here is the QR code to a PDF of the poster. Glad you found it interesting! If you have any questions or want more details, happy to chat about it! 🙂

Mixed-effects modellers, assemble!

Just dropped a (very niche) blog on the weird quirks that occur with uncorrelated random effects and the trifecta of packages: lme4, afex, and performance (in R).

So happy this is finally out! Despite Covid delays and thanks to persistence by @arimoccia.bsky.social + the helpful reviewers

Starting to uncover how memory cues and goals interact - with implications for how we understand memory reconstruction during retrieval

Thank you Giuli!! 🙏

Happy publication day to first author @ewanmurray.bsky.social! A lot of hard work by Ewan went into this, so it is great to see if fully published.

Results suggest at least two stages of selection within the retrieval cascade: 1) external cues modify which memories get reinstated & 2) further goal-driven processing amplifies targeted memories in line with goals. For simple model inspired by doi.org/10.1016/j.ti... 🧵8/9

Final result: people also reinstated neural patterns as they prepared to retrieve the upcoming trial (at least when cues were words). As predicted by the encoding specificity principle this preparatory goal-related reinstatement may be how selective retrieval is achieved🧵7/9

This differed with our original findings for the left parietal ERP. This ERP (Bottom Left) was more target-selective than reinstatement (Top Left) when cues matched targets more, but when cues matched non-targets more, only reinstatement was selective for non-targets (Right for comparison)🧵6/9

Decoding of scalp ERPs showed: reinstatement of study phase neural patterns was target-selective when the external cues matched targets = audio with word cues (Exp1) or pictures with picture cues (Exp2), but was reversed (non-target > target) when cue match was greater with non-targets🧵5/9

But the left parietal ERP may reflect the outcome of high-level cortical processing during recollection. As goal-driven reconstruction can transform initial pattern-completed neural representations, we reasoned that goals and cues might impact recollection at multiple stages🧵4/9

In earlier study, people had to retrieve target objects studied as audios or pictures (in #CABN see doi.org/10.3758/s134...). Retrieval success ERPs (left parietal effect) were target-selective (> non-targets) – but only when external cues matched the targeted information🧵3/9

When remembering, people reactivate neural patterns of original events. This neural reinstatement is initiated when the hippocampus pattern-completes studied events from retrieval cues. Given a cue, would goals modify reinstatement so it's selective for targeted memories?🧵2/9

How are relevant memories selected out of a large store of events? We measured🧠#EEG neural reinstatement to test how selective memory retrieval is achieved 🧵1/9

The Effects of External Cue Overlap and Internal Goals on Selective Memory Retrieval as Revealed by Electroencephalographic (EEG) Neural Pattern Reinstatement This EEG study used multivariate decoding in humans to investigate how memories are selected when retrieval goals vary. The results showed that EEG neural patterns reinstating studied information tra...
