1. Role of α2-adrenoceptors in the lateral parabrachial nucleus in the control of body fluid homeostasis
Central α2-adrenoceptors and the pontine lateral parabrachial nucleus (LPBN) are involved in the control of sodium and water intake. Bilateral injections of moxonidine (α2-adrenergic/imidazoline receptor agonist) or noradrenaline into the LPBN strongly increases 0.3 M NaCl intake induced by a combined treatment of furosemide plus captopril. Injection of mo

2. Changes in sodium appetite evoked by lesions of the commissural nucleus of the tractus solitarius
Ablation of the area postrema/caudal nucleus of the tractus solitarius (NTS) complex increases sodium intake, but the effect of selective lesions of the caudal NTS is not known. We measured depletion-induced sodium intake in rats with electrolytic lesions of the commissural NTS that spared the area postrema. One day after the lesion, rats were depleted of so

3. Mecanismos adrenérgicos do núcleo parabraquial lateral e da área Kölliker Fuse/A7 no controle da ingestão de água e sódio
The blockade of serotonergic receptors with methysergide or the activation of α2-adrenoceptors with moxonidine into the lateral parabrachial nucleus (LPBN) increases water and 0.3 M NaCl intake in rats treated with furosemide (FURO) combined with captopril (CAP). Besides LPBN, also the Kölliker-Fuse nucleus/A7 area (KF/A7 area) located at the rostral a

4. Núcleo central da amígdala e Núcleo parabraquial lateral no controle da ingestão de sódio
Previous studies have shown the importance of serotonergic GABAergic and aadrenergic mechanisms of the lateral parabraquial nucleus (LBPN) in the control of sodium intake. The importance of the central nucleus of the amygdala (CeA) for sodium intake induced by different protocols was also demonstrated. Considering the studies showing reciprocal connections b

5. Temporal evaluation of c-fos expression in amygdaloid and hypothalamic areas following experimental tooth movement in rats / Avaliação temporal da expressão da proteína FOS em áreas amigdalóides e hipotalâmicas após movimentação dentária experimental em ratos
In the accomplishment of the orthodontic treatment, it is described that the pain happens immediately after the application of orthodontic forces and disappears after few days. Regarding the neural pathways involved in the sensorial mediation of the orthodontic movement (OM) few are the studies that approach this theme, and in the last decades solid founds d

6. Lesions of the commissural subnucleus of the nucleus of the solitary tract increase isoproterenol-induced water intake
The nucleus of the solitary tract (NTS) is the primary site of the cardiovascular afferent information about arterial blood pressure and volume. The NTS projects to areas in the central nervous system involved in cardiovascular regulation and hydroelectrolyte balance, such as the anteroventral third ventricle region and the lateral parabrachial nucleus. The

7. Water deprivation and the double- depletion hypothesis: common neural mechanisms underlie thirst and salt appetite
Water deprivation-induced thirst is explained by the double-depletion hypothesis, which predicts that dehydration of the two major body fluid compartments, the extracellular and intracellular compartments, activates signals that combine centrally to induce water intake. However, sodium appetite is also elicited by water deprivation. In this brief review, we

8. Participação dos receptores adrenérgicos Alfa2 do núcleo parabraquial lateral no controle da ingestão de sódio.
Water and NaCl intake is strongly inhibited by the activation of α2-adrenergic receptors with clonidine or moxonidine (α2-adrenergic/imidazoline agonists) injected peripherally or into the forebrain and by serotonin and cholecystokinin into the lateral parabrachial nucleus (LPBN), a pontine structure. Serotonergic and cathecolaminergic neurons are

9. Efeitos da lesão do núcleo do trato solitário comissural sobre a ingestão de água e sólido.
The central nervous system (CNS) has an important function in the regulation of homeostatic mechanisms controlling the volemia and osmolality of the body fluid. The nucleus of the tract solitary (NTS) is the primary site of the cardiovascular afferents and peripheral osmoreceptors. From to NTS, the information about arterial blood pressure, extracellular flu

10. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

11. Afferent connections of the amygdalopiriform transition area (APir) of the rat. / Conexões aferentes da área de transição amígdalo-piriforme (APir) no rato.
The amygdalo-piriform transition area (APir) lies at the junction of the piriform, periamygdaloid and entorhinal cortices. The afferent connections of this olfactory district were studied with retrograde tracing methods using the cholera toxin B subunit and Fluoro-Gold as tracers. Our retrograde experiments showed that the main input sources to APir derive f

12. Brainstem control of response modes in neurons of the cat's lateral geniculate nucleus.
The visual pathway from retina through the lateral geniculate nucleus to visual cortex in the cat is comprised of several parallel neuronal streams that independently analyze different aspects of the visual scene. The best known of these are the X and Y pathways that relay through the geniculate A laminae. Recent receptive-field studies of retinal and genicu
