Ketanserin effects on rat behavioral responses: Modifications by the estrous cycle, ovariectomy and estradiol replacement
(1997)
The present investigation was designed to explore the influence of estrous cycle phase, ovariectomy, and estradiol replacement on the behavioral effects of the 5-HT2 receptor antagonist, ketanserin. The parameters under ...
Serotonergic outcome, stress and sexual steroid hormones, and growth in a South American cichlid fish fed with an l-tryptophan enriched diet
(Academic Press Inc Elsevier Science, 2015-11)
Reared animals for edible or ornamental purposes are frequently exposed to high aggression and stressful situations. These factors generally arise from conspecifics in densely breeding conditions. In vertebrates, serotonin ...
An Early Disturbance in Serotonergic Neurotransmission Contributes to the Onset of Parkinsonian Phenotypes in Drosophila melanogaster
(MDPI, 2022)
Parkinson's disease (PD) is a neurodegenerative disease characterized by motor symptoms and dopaminergic cell loss. A pre-symptomatic phase characterized by non-motor symptoms precedes the onset of motor alterations. Two ...
Body Sodium Overload Modulates the Firing Rate and Fos Immunoreactivity of Serotonergic Cells of Dorsal Raphe Nucleus
(Public Library of Science, 2013-09)
In order to determine whether serotonergic (5HT) dorsal raphe nucleus (DRN) cells are involved in body sodium status regulation, the effect of a s.c. infusion of either 2 M or 0.15 M NaCl on 5HT DRN neuron firing was studied ...
Opioidergic, GABAergic and serotonergic neurotransmission in the dorsal raphe nucleus modulates tonic immobility in guinea pigs
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-01)
Tonic immobility (TI) is an innate defensive behavior that can be elicited by physical restriction and postural inversion and is characterized by a profound and temporary state of akinesis. Our previous studies demonstrated ...
Human Raphe Magnus Nucleus: A morphometric Golgi-Cox study with emphasis on sex differences
(2001)
The number and proportion of neurons according to their type and size in the Raphe Magnus Nucleus stained by the Golgi-Cox and Nissl methods were compared in male and female infants. Four female/male pairs aged from 2 to ...
Sexual dimorphism in number and proportion of neurons in the human median raphe nucleus
(ELSEVIER, 2000)
The number and proportion of neurons in the median raphe nuclei stained by the Golgy-Cox and Nissl methods was compared in males and females infants. When subjects are matched by age and cause of death the number and ...
Effect of central acute administration of cadmium on drinking behavior
(1996)
The effect of acute third ventricle cadmium administration on the drinking behavior of adult male rats under different situations was studied. Injections of cadmium chloride (0.07, 0.7, and 7.0 ng/rat) significantly ...
