A Golgi study of the plasticity of dendritic spines in the hypothalamic ventromedial nucleus during the estrous cycle of female rats

A Golgi study of the plasticity of dendritic spines in the hypothalamic ventromedial nucleus during the estrous cycle of female rats

Highlights • Hypothalamic ventromedial nucleus (VMN) showed plasticity over estrous cycle. • Spine density in HVM interneurons was less in metaestrus than in the other stages. • Thin and mushroom spines were less in metaestrus than in the other stages. • Thin and stubby spines increased in estrus co...

Zusammenfassung:Highlights • Hypothalamic ventromedial nucleus (VMN) showed plasticity over estrous cycle. • Spine density in HVM interneurons was less in metaestrus than in the other stages. • Thin and mushroom spines were less in metaestrus than in the other stages. • Thin and stubby spines increased in estrus compared with the other stages.
