Obesogenic Diet Impairs Social Memory Through Alterations of Hippocampal CA2 Excitability and Oxytocin Signaling

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.

Morphological differences along the radial gradient of hippocampal area CA2 pyramidal neuron dendrites

The paper examines dendritic morphology of CA2 and CA1 pyramidal neurons, finding gradual morphological changes along the radial axis that suggest a continuum rather than distinct subtypes.

Local circuit allowing hypothalamic control of hippocampal area CA2 activity and consequences for CA1

This study identifies how hypothalamic SuM input modulates hippocampal CA2 circuitry, enhancing firing precision and influencing CA1 activity through synchronized inhibition.

Actomyosin-mediated nanostructural remodeling of the presynaptic vesicle pool by cannabinoids induces long-term depression

This study shows that cannabinoids induce long-term depression by remodeling presynaptic vesicle pools through actomyosin contractility.
