So happy to finally see this out in @currentbiology.bsky.social! We found that disrupted replay structure in an AD model was linked to reduced place cell stability and more repetitive behaviour on a radial maze 🧠 @abrate.bsky.social @caswell.bsky.social #neurosky

Disrupted hippocampal replay is associated with reduced offline map stabilization in an Alzheimer’s mouse model
Shipley et al. show that spatial memory deficits in an Alzheimer’s mouse model are associated with place cell instability and degraded reactivations in rest. Although reactivation rates are preserved,...

Memory dysfunction in Alzheimer’s disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice led by Dr Sarah Shipley @shipleysj.bsky.social and Prof Caswell Barry @caswell.bsky.social @ucllifesciences.bsky.social

OK If we are moving to Bluesky I am rescuing my favourite ever twitter thread (Jan 2019).

Excited to share that our preprint is out!
doi.org/10.1101/2024...

The structure of place cell reactivations was disordered in AD mice compared to WT! This was predictive of reduced place cell stability and memory performance on a radial-arm maze task.

Here are a few details:

Disordered Hippocampal Reactivations Predict Spatial Memory Deficits in a Mouse Model of Alzheimer's Disease
Alzheimer's disease (AD) is characterised by progressive memory decline associated with hippocampal degeneration. However, the specific physiological mechanisms underlying hippocampal dysfunction in A...

Our latest preprint has landed www.biorxiv.org/content/10.1...
Fantastic work from @laurenb29.bsky.social and Will de Cothi showing how many of the cell types associated with subiculum (e.g. boundary vector cells, corner cells) can be understood as successor features. TLDR: SUB not CA1 is the SR
Unifying Subicular Function: A Predictive Map Approach
The successor representation has emerged as a powerful model for understanding mammalian navigation and memory; explaining the spatial coding properties of hippocampal place cells and entorhinal grid ...

Huge congrats to @karyna-mi.bsky.social for her paper published today in Science! She found that the hippocampus is really important for a key strategy we use to make decisions called hidden state inference! 🧪 🧠https://www.science.org/doi/10.1126/science.adq5874 1/7
Hidden state inference requires abstract contextual representations in the ventral hippocampus
The ability to use subjective, latent contextual representations to influence decision-making is crucial for everyday life. The hippocampus is hypothesized to bind together otherwise abstract combinat...

What are the brain’s “real” tuning curves?

Our new preprint "SIMPL: Scalable and hassle-free optimisation of neural representations from behaviour” argues that existing techniques for latent variable discovery are lacking.

We suggest a much simpl-er way to do things.
