Excited to share a new preprint w/ @annaschapiro.bsky.social! Why are there gradients of plasticity and sparsity along the neocortex–hippocampus hierarchy? We show that brain-like organization of these properties emerges in ANNs that meta-learn layer-wise plasticity and sparsity. bit.ly/4kB1yg5

A gradient of complementary learning systems emerges through meta-learning

Long-term learning and memory in the primate brain rely on a series of hierarchically organized subsystems extending from early sensory neocortical areas to the hippocampus. The components differ in t...

Incredibly excited and grateful to share that I’ll be starting a lab at The Ohio State University this(!) fall! My lab will study human learning and memory, with related interests in sleep, stress, and time perception. More info soon, but do get in touch if you’re interested in joining!

preprint alert 🚨
1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

Amazing & comprehensive work by @brynnsherman.bsky.social demonstrating how sleep reactivation supports the integration of new info into existing knowledge. So excited to see this out!!

Brynn Sherman @brynnsherman.bsky.social · Jun 10

New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism.

New preprint! Statistical structure skews object memory toward predictable successors. Model simulations show how this bias can arise from the backward expansion of hippocampal representations.
