Has the concept of systems consolidation outlived its usefulness? Should we talk about memory system *reorganization* rather than *consolidation*?

Intriguing argument by Moscovitch & Gilboa

Has the concept of systems consolidation outlived its usefulness? Identification and evaluation of premises underlying systems consolidation

Systems consolidation has mostly been treated as a neural construct defined by the time-dependent change in memory representation from the hippocampus (HPC) to other structures, primarily the neocortex. Here, we identify and evaluate the explicit and ...

How do we balance paying attention to the external world around us vs. our internal thoughts and memories?

The hippocampus shows differential coupling with the cholinergic basal forebrain and the dorsal attention network for externally cued vs. memory-guided attention.

So proud of grad student Craig Poskanzer for leading this project!

Our study showing long-term changes in synaptic ultrastructure after exposure to general anesthesia in infancy is (finally) out in full form: https://www.cell.com/iscience/fulltext/S2589-0042(22)01958-7

Finally, with fMRI we showed that replaying memory cues increased the differentiation of activity patterns in the hippocampus, and that the degree of hippocampal differentiation was associated with greater episodic recall.

Stay tuned for more HippoCamera research! We’re running lots of studies to see whether and how HippoCamera can benefit other populations. More about the project here: https://hippocamera.com/.

Please get in touch if you’d like to use HippoCamera in your own research! (4/4)

HippoCamera

Preserving Lasting Memories For Life Events

@honey In addition to these memory gains, a text-based natural language analysis showed that memories replayed with HippoCamera were recalled with more positive emotional sentiment, relative to baseline events. (3/4)

@honey Across two experiments, we found large benefits in older adults' recollection of event-specific details, ranging from 56% to 84%, relative to a within-subject baseline condition. This memory benefit was still evident 3 months after discontinuing HippoCamera use. (2/4)

I’m very proud to share: A smartphone intervention that enhances real-world memory and promotes differentiation of hippocampal activity in older adults.

Over the last 8 years, we developed @HippoCamera as an easy-to-use smartphone app that embodies principles from memory science to record and replay brief but powerful memory cues of everyday events.

New preprint with @charanranganath - - Integration of event experiences to build relational knowledge in the human brain, https://www.biorxiv.org/content/10.1101/2022.11.17.516960v1

How does the brain build event concepts from experiences? We show that episodic and semantic memory areas both participate, at different times.

For the past few weeks I've been working on building a service that connects online experiments to the OSF, so that data are automatically sent to the OSF and you don't need a server to run experiments.

It's almost ready, and I'm looking for a few people who would be willing to try it out for real and provide feedback. Volunteers must be willing to tolerate bugs and such. If this goes smoothly then it should be ready for a wider launch in January.

If you're interested get in touch!

Now that I'm moved to neuromatch.social, a new #introduction.

I’m a professor at UPenn who studies memory. I work at the nexus of brain research and computation. I’m also writing a book: When it comes to understanding the brain, what are we trying to achieve? What’s our plan to get there? What challenges do we face?

Writing has deepened my appreciation for community-based progress. I'm excited to be here to participate in, and benefit from, collective intelligence.

I'm also committed to restraining myself from the power of 10K characters. But I will Edit - that is the superpower that we all deserve.
