Patterns of hypothalamic GnIH change over the reproductive period in starlings and rats

Highlights • Patterns of GnIH were characterized over the breeding period in starlings and rats. • GnIH cell abundance changed at important transitions of the parental care stage. • Cell abundance increased when birds began to incubate eggs and when chicks hatched. • Cell abundance decreased 1 day p...

Zusammenfassung:Highlights • Patterns of GnIH were characterized over the breeding period in starlings and rats. • GnIH cell abundance changed at important transitions of the parental care stage. • Cell abundance increased when birds began to incubate eggs and when chicks hatched. • Cell abundance decreased 1 day postpartum in rats. • In both, offspring removal increases GnIH cell abundance.
