In medaka fish, galanin-expressing neurons in the medial preoptic area occur nearly exclusively in males and mediate androgen-dependent male–male aggressive chases.

Preoptic neurotensinergic neurons co-release GABA and neurotensin, triggering a rapid initial inhibition followed by a sustained excitation, and mice lacking GABA release from these neurons exhibit altered thermoregulation.

Despite voluntary exercise being rewarding to mice, pregnancy hormones act in the maternal brain to markedly reduce the time females choose to engage in this activity.

Preoptic area neurons co-expressing GABA and kisspeptin are essential for the preovulatory surge mechanism but not for the pulsatile secretion of luteinizing hormone.

Preoptic area of the hypothalamus is important for the homeostatic regulation of rapid eye movement sleep.

Central SNS outflow sites originating from 87 brain nuclei and sub-nuclei in six brain divisions innervate bone.

A brain-wide map of neural activation reveals how sexual experience becomes a pair bond in the monogamous prairie vole.

The most comprehensive neuroanatomical atlas on the expression of three glycoprotein hormone receptors, namely, TSHRs, LHCGRs, and FSHRs, was mapped using RNAscope, a technology that allows the detection of mRNA at single-transcript level.

Warm-activated parabrachial neurons contain overlapping dynorphin and enkephalin expressing subpopulations, project to preoptic hypothalamus, and mediate behavioral and physiological thermal defenses behaviors.
