Excited to share our new publication on the influence of odor perception on memory. Congratulations to @joantarridav.bsky.social for initiating this fascinating line of research in our lab.

🚨 New preprint alert!

Excited to share our latest work on alpha/beta activity, eye movements, and memory.

Across 4 experiments combining scalp EEG/iEEG with eye tracking, we show that alpha/beta activity directly reflects eye movements, and only indirectly relates to memory.

👇 Highlights (1/7):

Are the brain's representational formats predetermined by its intrinsic architecture, or are they efficiently tuned to the statistical structure of the visual world? In our new study, we test these possibilities.

So proud of this fantastic and inspiring work, led by @jazzmaniatico.bsky.social.

1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

For anyone in the memory field, an incredible summary and tribute to Endel Tulving from Gus Craik. Read it for the writing alone.

New preprint! 🚨→ Determinants of Visual Ambiguity Resolution. A new work with @ortiztudela.bsky.social @jvoeller.bsky.social @martinhebart.bsky.social and @gonzalezgarcia.bsky.social

We created ~2k images and collected ~100k responses to study visual ambiguity.

Evolving Engrams Demand Changes in Effective Cues A longstanding principle in episodic memory research, known as the encoding specificity hypothesis, holds that an effective retrieval cue should closely match the original encoding conditions. This p...

New paper out! 🎉 “Evolving Engrams Demand Changes in Effective Cues” (Hippocampus). In this opinion piece, we discuss how retrieval processes can be enhanced and offer an alternative to one of the field’s few enduring principles: encoding specificity. onlinelibrary.wiley.com/doi/10.1002/...

Social Network Structure Shapes the Formation of True and False Memories at the Collective Level Societal structures and memory organization models share network-like features, offering insights into how information spreads and shapes collective memories. In this study, we manipulated the struct....

2/2 Using DRM lists, we examined how social structure affects memory in lab-created communities. Clustered groups reinforced true memories, while non-clustered ones increased false memories, shaping collective knowledge.

Now out in @cogscisociety.bsky.social: onlinelibrary.wiley.com/doi/10.1111/...

1/2 Just like social groups, human memory is organized in interconnected patterns. Activating one memory can trigger related ones, similar to how information spreads through a community. Could social sharing shape how memories are formed?

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences.

We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)

Deep learning models and brains share fascinating parallels in their ability to process and instantly integrate new knowledge.

Join us this year at ICON 2025 to discuss how sudden learning emerges across artificial and biological systems! 🧠🤖

Congratulations, Ben!!

Awake replay: off the clock but on the job Hippocampal replay is widely thought to support two key cognitive functions: online decision-making and offline memory consolidation. In this review, we take a closer look at the hypothesized link bet...

New opinion paper in @cp-trendsneuro.bsky.social with Dan Bendor, where we argue that rodent studies provide only marginal support for the idea that replay supports real-time decisions (e.g. planning). Fictive learning and memory tagging are more consistent w/evidence. www.cell.com/trends/neuro...
