Cerebrospinal fluid (CSF)-contacting neurons form a part of the circumventricular organs of the central nervous system. Represented by different cytologic types and located in different regions, they constitute a CSF-contacting ...

Cannabinoid receptors are sparsely distributed in the hypothalamic nuclei, although they seem to be located on key neurons because their activation produces important neuroendocrine effects. In the present study, we have ...

The expression of cholecystokinin (CCK) mRNA in neuroendocrine corticotropin-releasing hormone (CRH) neurons of the hypothalamic paraventricular nucleus (PVN) of male rats was examined 8 h following an acute immune challenge ...

The secretion of prolactin (PRL) is stimulated by thyrotropin-releasing hormone (TRH), and inhibited by dopamine (DA). However, we have recently demonstrated that salsolinol (SAL), a DA-derived endogenous compound, is able ...

The aim of this study is to characterize calbindin-positive photoreceptors and their opsin content in the retina of nocturnal prosimians (Microcebus murinus), New World monkeys (Callithrix jacchus), Old World monkeys (Macaca ...

PURPOSE: Rats are the most commonly used animal model for studies of acute lower limb ischemia-reperfusion. The ischemia induced by arterial clamping may cause milder damage than the application of a tourniquet if the ...

The breeding of birds is expected to solve problems of nourishment for the growing human population. The function of the pineal organ synchronizing sexual activity and environmental light periods is important for ...

By means of double-label immunocytochemistry, authors studied the presence of estrogen receptor alpha (ER-alpha) protein in vesicular glutamate transporter 2 (VGluT2) protein-immunoreactive neurons in the female rat ...

Secretin shows a wide distribution in the brain. Functional significance of central secretin is stressed since it has been associated with autism and schizophrenia. The presence of the secretin receptor was previously ...
