  1. 🧠 New preprint by Zhong et al. proposes a #synaptic mechanism for #chunking in #WorkingMemory.

    Using short-term #plasticity and synaptic augmentation, their model shows how items can be temporarily suppressed and later retrieved as chunks, increasing effective capacity w/o increasing simultaneous activity.

  2. 📖 Vaidya et al. investigate how #hippocampal #CA1 #PlaceCells form expanding #memory representations over days. Using longitudinal in vivo recordings, they show that stable #PlaceFields progressively emerge as active cells increase their likelihood of remaining active across sessions. This gradual stabilization hinges on #behavioral‑timescale #SynapticPlasticity, offering a new model of how CA1 memories solidify w/o #CatastrophicOverwriting.

  3. Recently, we discussed this insightful paper by Squadrani et al (2024) in our #JournalClub. It explores how #astrocytes enhance #SynapticPlasticity during #ReversalLearning by modulating D-serine levels, providing a #biophysical basis for dynamic #LTP thresholds. The findings suggest astrocytic signaling is crucial for #AdaptiveLearning, linking #glial activity to #behavioral flexibility. Here’s a summary from our JC:
