    4 experiments and >440 participants later... my first postdoc project! We find that semantic knowledge can boost accuracy of new episodic memories, but the way that it is organized can also affect how those memories are distorted.

    Put Mixed Model series R material into bookdown format. If you don't feel like watching the videos, you can read about it instead! Will be expanding as new videos come out.

    Memories are organized by their spatial study context. These contextual features are being reinstated with distinct time courses in hippocampus and surrounding MTL, while theta power increase is common to these regions!

    How does the thalamus contribute to memory? Mediodorsal thalamus has a material-general role in familiarity; anterior thalamus has a material-general role in recollection Mediodorsal thalamus coupling w/ MTL cortex is related to familiarity confidence

    Check out our new work with , , and ! We show that hippocampal place cells remap in similar + predictable ways across rats. This challenges the standard view that place cell remapping is random. 🐀🧠🗺️ Preprint here:

    I spent four years learning to run efficient regression analyses in R. Now I've written them into some handy functions so you won't have to.

    We're excited to honor Endel Tulving by synthesizing all our findings on familiarity deficits in patient NB!

    And the other side of this dissociation illustrated in this review by and coincidentally published today: patient NB has perirhinal lesion sparing hippocampus, with impaired familiarity but spared episodic recollection.

    Boundary extension is not universal - contractions are actually more common for scenes. These transformations are predictable by image properties, and happen even in a perceptual task. New paper by me and now out in :

    Collaboration with and showing relationships between executive function and HPC-vmPFC development. Even if you are not into development, the implications for HPC circuitry are pretty cool.

    Object-oriented images cause boundary extension — but scene-oriented images cause boundary contraction. This happens even when participants are copying an image right in front of them This paper by & looks amazing!

    Good start to the year - another paper of my PhD has just been published! I am really excited and proud to share this work.🎉 If you are interested in sleep and aging research, check out how and I dissect some of the field's core challenges.

    Though-provoking study on pattern separation: Mnemonic discrimination is associated with familiarity rather than recollection.

    Interested in the relationship between schemas and the episodes that make them up? Check out our new preprint! We find that episodic retrieval relies more on schematic memory over time, even as the schemas themselves become less precisely remembered.

    New prepint! We found that similar memories repel away from one another over learning such that they are remembered as further apart than they were experienced. These distortions were associated with reduced interference suggesting an adaptive mechanism.

    What are the important components of episodic memory? & Andy Yonelinas propose that the precision of spatiotemporal binding helps clarify how we represent context and the role of the hippocampus in memory and other cognitive functions.
