Associative and predictive hippocampal codes support memory-guided behaviors
Episodic memory involves learning and recalling associations between items and their
spatiotemporal context. Those memories can be further used to generate internal models of …

Adaptive stimulus selection for consolidation in the hippocampus
Associative memories guide behavioural adaptation by binding together outcome-predictive
sensory stimuli,. However, in a feature-rich environment, only a subset of stimuli may predict …

Phase information is conserved in sparse, synchronous population-rate-codes via phase-to-rate recoding
D Müller-Komorowska, B Kuru, H Beck… - Nature …, 2023 - nature.com
Neural computation is often traced in terms of either rate-or phase-codes. However, most
circuit operations will simultaneously affect information across both coding schemes. It …

Inhibitory plasticity supports replay generalization in the hippocampus
Memory consolidation assimilates recent experiences into long-term memory. This process
requires the replay of learned sequences, although the content of these sequences remains …
