How do we balance external attention to the outside world and internal attention to our thoughts & memories?

We review evidence that external and internal attention can compete, unfold concurrently, or cooperate!

Loved working on this with @samversc.bsky.social & @tobiasegner.bsky.social!

We've posted a new fMRI study of semantic relations (has-part, is-a, made-of, etc.), a key aspect of language. We find that relations are represented in the same brain regions as are other semantic concepts, though voxels tend to be selective for only one relation or another.

What episodic memory reveals about the default mode network osf.io/preprints/ps...

Adaptive episodic memory: how multiple memory representations drive behavior in humans and nonhumans | Physiological Reviews | American Physiological Society Episodic memory is a declarative long-term memory of a specific past experience. As such, it is multifaceted, encompassing both the objective and subjective components of that experience. These components can be flexibly represented at different levels of granularity, from precise, context-specific details to generalized, gistlike representations. In this review, we suggest that 1) multiple representations of an episodic memory at different levels of granularity are simultaneously encoded into a memory trace and 2) the relative weighting of these representations determines the extent to which a memory is reconstructed or reproduced at retrieval. We propose that this representational flexibility drives adaptive behavior by prioritizing reconstruction or reproduction depending on the age of the memory, its relationship to prior knowledge, current attentional goals or task demands, and individual differences. Drawing on research in humans and nonhuman animals, we show a close correspondence between psychological and neural representations of a memory across encoding, consolidation, and retrieval. Specifically, we discuss how hippocampal activity in humans and engram formation and activation in rodents support the reproduction of detailed memory representations, whereas schema formation across species, mediated by the medial prefrontal cortex, facilitates reconstruction and generalization to guide behavior. Finally, we consider how species- and individual-level differences shape episodic memory representations. By integrating findings across species, we illustrate how the correspondence between neural and psychological representations enables multiple memory representations to balance stability and flexibility, ultimately driving adaptive behavior.

How do memories guide behaviour?

Multiple memory representations, from detailed to gist-like, let us flexibly reconstruct or reproduce past experiences to behave adaptively across species.

We test the link between serial dependence (as an index of continuity) and event boundaries (indexing segmentation). A few key findings in the thread:

1/7 Can infants recognise the world around them? 👶🧠 As part of the FOUNDCOG project, we scanned 134 awake infants using fMRI. Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

Passage of time in the brain, in the mind, both?

Nine subcortical/cerebellar atlases included in the subcortex_visualization Python package (and subcortexVisualizationR package in R). The atlases are depicted in two-dimensional vector graphic format.

The extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

Functional Magnetic Resonance Imaging in Awake Infants: Insights From More Than 750 Scanning Sessions Functional magnetic resonance imaging (fMRI) in awake infants has the potential to reveal how the early developing brain gives rise to cognition and behavior. However, awake infant fMRI poses signifi....

Awake infant fMRI offers a rare window into early brain and cognitive development. In a new paper out now in Infancy, we leverage data from hundreds of infant scans from the Saxe and Turk-Browne Labs to reveal what factors drive scanning success — and how future studies can maximize data retention!

Great work by Roni Tibon (not on BlueSky) - surprising that negligible difference in fMRI correlates of semantic vs episodic retrieval?

We can use past experience to make predictions about the future. How do predictions affect our memory for the present? My own work (tinyurl.com/42kyukch) suggests that predictions compete with memory. But other recent work (tinyurl.com/2ekd4wr6) found the opposite--cooperation! What's going on here?

My lab is recruiting a postdoc and a full-time research technician to work on an NIH-funded project studying age-related changes in memory for naturalistic events. Behavior, fMRI, and blood-based biomarkers. 3+ years funding guaranteed.

Can reward improve memory for what came before it? 🌟

Words change: “broadcast” once meant scattering seeds; “tweet” was just a bird sound. Do older adults keep earlier meanings, or update as language evolves?

How do changes in context influence how we organize our memories in time?

Faster contextual changes are associated with faster drift in hippocampal activity and reduced temporal clustering in recalled memories.
