Yes, that’s the right intuition! In the model, the proportion of remote replay in those conditions depends on suppression strength. If you turn suppression off, remote replay still occurs at a modest level and should be matched between Alt and R/L, assuming experience is matched.
Great point! In the model, wake has much higher learning rates than rest/sleep, so that’s where biggest discrepancies across items arise, making balancing most needed after wake. We don’t propose suppression only acts on wake activity in the brain. An extension is to also adapt during sleep/rest.
My lab is hiring!
We have an opening for a full-time RA to focus on computational modeling and fMRI analysis. Programming skills are required. Psych/cog/neuro experience not necessary but a big plus. A great fit for someone who wants lab experience before grad school.

I'm recruiting a lab manager for my soon-to-be-launched lab at Ohio State! If you know of any recent grads who may be interested both in helping to build the lab and in developing skills in the cognitive neuroscience of memory, please share!

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
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.
