Metabolic effects of galanin injections into the paraventricular nucleus of the hypothalamus
Peptides, 1992The metabolic effects of single injections of galanin into the paraventricular nucleus of the hypothalamus (PVN) were investigated in an open-circuit calorimeter. Wistar rats were tested, with no food available during the tests. In the dose range of 0.03-0.3 nmol, galanin produced a very short-latency (approximately 2 minutes) and short-lasting ...

Experimental Neurology, 1973
Abstract Paraventricular cells in the rabbit were studied in response to stimulation in the hypothalamohypophyseal tract and the afferent pathway from the mammary gland. Three conditions were used in different preparations: urethane-anesthesia, unanesthetized and unanesthetized following the administration of monoamine depletors ...

Adrenergic control of glycemia in the paraventricular nucleus of the hypothalamus in pigeons
Neuroreport, 2002The effects of local injections of adrenaline into the paraventricular nucleus (PVN) and into other anterior hypothalamic areas on blood glucose levels were investigated in conscious pigeons (Columba livia). Adrenaline evoked a reliable and potent increase in blood glucose levels when injected into the PVN; no glycemic change was observed after vehicle

Orexin action on oxytocin neurons in the paraventricular nucleus of the hypothalamus
NeuroReport, 2017Oxytocin neurons in the paraventricular nucleus (PVN) of the hypothalamus play an important role in food intake regulation. It has been shown that the secretion of oxytocin from the hypothalamus shows a diurnal circadian rhythmic pattern and disturbance of this pattern leads to the development of obesity.

The descending afferent connections of the paraventricular nucleus of the hypothalamus (PVN)
Brain Research Bulletin, 1981The distribution of afferents to the paraventricular nucleus of the hypothalamus (PVN) was studied following iontophoresis of horseradish peroxidase (HRP) into the nucleus. This report describes the descending connections to this structure. The PVN receives a substantial input from limbic system structures, especially from the lateral septal nucleus ...

Behavioral effects of diltiazem injected into the paraventricular nucleus of the hypothalamus
Pharmacology Biochemistry and Behavior, 1989The calcium channel inhibitor diltiazem is widely used as a medication for cardiovascular diseases. Some side effects have been reported after its administration, including changes in activity (apathy or hyperactivity) and feeding behavior (anorexia). Previous experiments have found that local administration of various peptides into the paraventricular

Nuclear inclusions in paraventricular nucleus neurons of the rat hypothalamus
Cell And Tissue Research, 1979This paper deals with the ultrastructure of two types of intranuclear inclusions, "microfilamentous spindle-shaped" and "crystalloid", present in paraventricular nucleus neurons of adult normal rats. These inclusions appear occasionally in some non-secretory neurons of the parvocellular system, but have never been seen in neurosecretory cells of the ...

Central control of penile erection: Role of the paraventricular nucleus of the hypothalamus
Progress in Neurobiology, 2005The paraventricular nucleus of the hypothalamus is an integration centre between the central and peripheral autonomic nervous systems. It is involved in numerous functions from feeding, metabolic balance, blood pressure and heart rate, to erectile function and sexual behaviour. In particular, a group of oxytocinergic neurons originating in this nucleus

The present experiments were designed to investigate the effect of local calcium application on the paraventricular nucleus (PVN) on arginine-vasopressin (AVP) release and blood pressure. A microinjection of 2 microliter of calcium gluconate 10% in the PVN elevated AVP levels to 71.6 +/- 8.7 pg/ml compared to 3.3 +/- 0.6 pg/ml in control rats receiving

Metabolic modulation by amino acid stimulation of the paraventricular nucleus of the hypothalamus
Pharmacology Biochemistry and Behavior, 1993The role of the paraventricular nucleus of the hypothalamus (PVN) in the regulation of energy expenditure and energy substrate utilization was investigated after the injection of the excitatory amino acid D,L-homocysteic acid (DLH) or its vehicle. Male Wistar rats with chronic PVN cannulae were tested for 1 h with no food available in an open-circuit ...
