Role of the Preoptic Area in Sleep and Thermoregulation [PDF]
Frontiers in Neuroscience, 2021 Sleep and body temperature are tightly interconnected in mammals: warming up our body helps to fall asleep and the body temperature in turn drops while falling asleep.

Astrocytes in the Ventrolateral Preoptic Area Promote Sleep [PDF]
The Journal of Neuroscience, 2020 Although ventrolateral preoptic (VLPO) nucleus is regarded as a center for sleep promotion, the exact mechanisms underlying the sleep regulation are unknown. Here, we used optogenetic tools to identify the key roles of VLPO astrocytes in sleep promotion.

Nature Communications, 2022 The mechanisms coordinating the sensing and seeking of social contacts are unclear. Here, the authors show that amylin-calcitonin receptor signalling in the media preoptic area mediates affiliative social behaviors in female mice.

Estrogen-sensitive medial preoptic area neurons coordinate torpor in mice
Nature Communications, 2020 Torpor is a state of reduced metabolism and body temperature that conserves energy when food is scarce. Here the authors show that estrogen-sensitive neurons in the hypothalamus regulate torpor in mice, maintaining torpor in both sexes but initiating ...

Post-ejaculatory inhibition of female sexual drive via heterogeneous neuronal ensembles in the medial preoptic area [PDF]
eLifeMale ejaculation acutely suppresses sexual motivation in male mice. In contrast, relatively little is known about how male ejaculation affects sexual motivation and sexual behavior in female mice.

Lateral preoptic area glutamate neurons relay nociceptive information to the ventral tegmental area [PDF]
Cell Reports, 2023 Summary: The ventral tegmental area (VTA) has been proposed to play a role in pain, but the brain structures modulating VTA activity in response to nociceptive stimuli remain unclear.

The Hypothalamic Preoptic Area and Body Weight Control [PDF]
Neuroendocrinology, 2017 The preoptic area (POA) of the hypothalamus is involved in many physiological and behavioral processes thanks to its interconnections to many brain areas and ability to respond to diverse humoral factors. One main function of the POA is to manage body temperature homeostasis, e.g.

Circadian Oscillations in the Murine Preoptic Area Are Reset by Temperature, but Not Light [PDF]
Frontiers in Physiology, 2022 Mammals maintain their internal body temperature within a physiologically optimal range. This involves the regulation of core body temperature in response to changing environmental temperatures and a natural circadian oscillation of internal temperatures.

Dopamine Activates Noradrenergic Receptors in the Preoptic Area [PDF]
The Journal of Neuroscience, 2002 Dopamine (DA) facilitates male sexual behavior and modulates aromatase activity in the quail preoptic area (POA). Aromatase neurons in the POA receive dopaminergic inputs, but the anatomical substrate that mediates the behavioral and endocrine effects of DA is poorly understood.

A calcitonin receptor-expressing subregion of the medial preoptic area is involved in alloparental tolerance in common marmosets [PDF]
Communications Biology, 2022 Like humans, marmoset caregivers exhibit individual parenting styles. Among these, infant tolerance is in part regulated by a subregion of the medial preoptic area enriched with calcitonin receptor-expressing neurons.
