This study investigates how CeA neurons encode behavioral features during habit formation in rats performing a maze task, finding increased cFos expression and specific outcome-related activity.

The paper shows that left-right alternation in hippocampal theta sequences is driven by medial entorhinal cortex dynamics, not intentional planning.

The paper examines cross-species differences in cortical-hippocampal projections across six mammals, finding that direct unimodal input from sensory regions is selectively eliminated as brain size increases.

This study shows that an obesogenic diet impairs social memory in mice by altering hippocampal CA2 excitability and oxytocin signaling, with specific effects on endocannabinoid plasticity and social novelty discrimination.

This study shows that the left medial habenula (MHb) in mice has functional asymmetry in fear expression, mediated by GABAB receptors, and this asymmetry is influenced by internal organ laterality.

The paper shows that prefrontal-thalamic pathways encode goal states in a way that allows hippocampal maps to remain spatially aligned across different navigation episodes.

This study investigates the molecular mechanisms of temporal order memory in mice, finding dynamic ERK2-MKP3 signaling in the prefrontal cortex and revealing behavioral features of memory retrieval.

The paper shows that the mouse anterior cingulate cortex uses dynamic single-cell activity to maintain stable population codes for object locations across repeated experiences.

In mice learning two tasks, cerebellar granule cells kept the low-rank geometry of premotor cortical output within each task but rotated their population trajectories apart between tasks, while cortex generalized.

This study investigates how sensory noise affects grid-patterned firing and path integration in a continuous attractor network, finding that low levels of noise can enhance performance through stochastic resonance.

This study examines darting behavior in rats during the PMA task, finding that social context influences darting frequency, speed, and location, suggesting it is a learned navigation strategy.

This study shows that mice and artificial neural networks reuse modular neuronal subspaces to perform complex cognitive tasks.

The paper builds a learning model to show how diverse spatial properties in the postrhinal cortex emerge from visual input processing through the superior colliculus pathway.

The paper shows that precise CA1 input topography shapes subicular spatial coding and network dynamics, while preserving single-cell tuning and impairing boundary vector coding and long-term stability.
