Nerve Centers Affecting the Function of the Cardiovascular System
Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2021 BACKGROUND AND OBJECTIVE: The activity of the cardiovascular system is carried out by the Autonomic Nervous System (ANS). ANS itself is controlled by multiple nerve centers.

Orexins in the paraventricular nucleus of the thalamus mediate anxiety-like responses in rats [PDF]
, 2010 Anatomical studies have shown that the paraventricular nucleus of the thalamus (PVT) innervates areas of the forebrain involved in the expression and regulation of emotional behaviors including fear and anxiety. In addition, the PVT is densely innervated

Circadian rhythm mechanism in the suprachiasmatic nucleus and its relation to the olfactory system
Frontiers in Neural CircuitsAnimals need sleep, and the suprachiasmatic nucleus, the center of the circadian rhythm, plays an important role in determining the timing of sleep. The main input to the suprachiasmatic nucleus is the retinohypothalamic tract, with additional inputs ...

Transcriptional regulation of corticotropin-releasing hormone gene in stress response
IBRO Reports, 2018 As a central player of the hypothalamic-pituitary-adrenal (HPA) axis, the corticotropin -releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) determine the state of HPA axis and play a key role in stress response.

Nature Communications, 2020 The TrkB receptor is known to regulate obesity via appetite control, but the underlying neural circuits are not known. Here, the authors show that selective modulation of TrkB+ neurons in the paraventricular hypothalamus regulates food intake via ...

Advanced Science, EarlyView.RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Environment and Behavior: Neurochemical Effects of Different Diets in the Calf Brain
Animals, 2019 Calves reared for the production of white veal are subjected to stressful events due to the type of liquid diet they receive. Stress responses are mediated by three main stress-responsive cerebral regions: the prefrontal cortex, the paraventricular ...

Bilateral descending hypothalamic projections to the spinal trigeminal nucleus caudalis in rats. [PDF]
PLoS ONE, 2013 Several lines of evidence suggest that the hypothalamus is involved in trigeminal pain processing. However, the organization of descending hypothalamic projections to the spinal trigeminal nucleus caudalis (Sp5C) remains poorly understood ...
