The Sleep-Promoting Ventrolateral Preoptic Nucleus: What Have We Learned over the Past 25 Years?

International Journal of Molecular Sciences, 2022
For over a century, the role of the preoptic hypothalamus and adjacent basal forebrain in sleep–wake regulation has been recognized. However, for years, the identity and location of sleep- and wake-promoting neurons in this region remained largely ...

Emotional‐cognitive differences during pregnancy: Adaptations for motherhood

Infant Mental Health Journal: Infancy and Early Childhood, EarlyView.
Abstract Emerging research suggests that unique adaptations in emotional cognition prepare pregnant women for motherhood. This study compared emotional‐cognitive responses to infant stimuli in 44 pregnant and 34 non‐pregnant Danish participants and explored associations with postpartum outcomes in pregnant participants.

Kisspeptin Activates Ankrd 26 Gene Expression in Migrating Embryonic GnRH Neurons

Frontiers in Endocrinology, 2016
Kisspeptin, a newly discovered neuropeptide regulates gonadotropin-releasing hormone (GnRH). Kisspeptins are a large RF-amide family of peptides. The kisspeptin coded by kiss1 gene is a 145-amino acid- protein that is cleaved to C-terminal peptide ...

Homeostatic regulation of REM sleep by the preoptic area of the hypothalamus

, 2023
ABSTRACTRapid-eye-movement sleep (REMs) is characterized by activated electroencephalogram (EEG) and muscle atonia, accompanied by vivid dreams. REMs is homeostatically regulated, ensuring that any loss of REMs is compensated by a subsequent increase in its amount.

Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

Estradiol in the Preoptic Area Regulates the Dopaminergic Response to Cocaine in the Nucleus Accumbens

Neuropsychopharmacology, 2015
The sex-steroid hormone estradiol (E2) enhances the psychoactive effects of cocaine, as evidenced by clinical and preclinical studies. The medial preoptic area (mPOA), a region in the hypothalamus, is a primary neural locus for neuroendocrine integration,

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]

, 2013
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...

Advent of NK3R Antagonists for the Treatment of Menopausal Hot Flushes: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT The menopause transition is marked by symptoms predominantly attributed to declining oestrogen levels. Approximately 80% of women experience associated symptoms, and 25% experience severe symptoms. The commonest are vasomotor symptoms (VMS), collectively referring to hot flushes and/or night sweats.

Identification of hypothermia-inducing neurons in the preoptic area and activation of them by isoflurane anesthesia and central injection of adenosine

Journal of Physiological Sciences
Hibernation and torpor are not passive responses caused by external temperature drops and fasting but are active brain functions that lower body temperature.

Estrogen mediates sex differences in preoptic neuropeptide and pituitary hormone production in medaka

Communications Biology, 2021
Junpei Yamashita et al. use a medaka model to evaluate how neurons in the preoptic area that express the neuropeptides, PACAP and VIP, regulate pituitary hormones. Their results suggest that estrogen helps maintain sex-dependent activity of these neurons,
