Frequency-specific theta states in the hippocampus are linked to reconfiguration of population activity with respect to behavioural context

The paper identifies two theta oscillation states in rats during an odor-memory task and links them to changes in hippocampal population activity related to trial outcomes.

Dissecting unsupervised learning through hidden Markov modelling in electrophysiological data

The paper evaluates how different assumptions in hidden Markov models affect state decomposition in electrophysiological data using synthetic and real data.

Differential activity patterns in the upper and lower blade of the dentate gyrus

The paper compares activity patterns in the upper and lower blades of the dentate gyrus during a decision-making task, finding distinct roles for each blade in encoding emotional and actual responses.

Novelty gates memory formation through ventro-dorsal hippocampal interaction

This study identifies a ventral hippocampal pathway that gates novelty-driven memory formation by activating dorsal hippocampal granule cells.
