This work addressed the study of subnucleus reticularis dorsalis (SRD) neurons in relation to their supraspinal input and the spinal terminating sites of their descending axons. SRD extracellular unitary recordings from anesthetized cats aimed to specifically test, 1) the rostrocaudal segmental level reached by axons of spinally projecting (SPr) neurons collateralizing or not to or through the ...

We compared in albino and pigmented rats the early effect of unilateral labyrinthectomy (UL) on the concentrations of monoamines (norepinephrine, dopamine, serotonin) and their respective metabolites--3-methoxy,4-hydroxyphenylglycol (MHPG), 3,4-dihydroxy-phenylacetic acid (DOPAC), and 5-hydroxyindoleacetic acid (5HIAA)--in medial vestibular nuclei (MVN), locus coeruleus, raphe dorsalis, and coc...

IMPORTANCE Animal data suggest that chronic stress is associated with a reduction in norepinephrine transporter (NET) availability in the locus coeruleus. However, it is unclear whether such models are relevant to posttraumatic stress disorder (PTSD), which has been linked to noradrenergic dysfunction in humans. OBJECTIVES To use positron emission tomography and the radioligand [11C]methylreb...

introduction: the septal region is part of the telencephalon and is a component of the limbic system. the lateral septal area (ls); largest nuclear mass in this region, plays a pivotal role in various physiological processes, such as aggression, emotion, thermoregulation, water and food intake and sexual behaviour. to support the functional analysis of this brain area in the rat, the sources of...

The medullary centers of blood pressure regulation have been in the field vision both physiologists and doctors for a very long period time. This is mainly due to abundance structures interstructural interactions brain stem, involved maintaining pressure. Advances research technology open new opportunities these days look at this problem from different angle. Moreover, will make it possible und...

Functional neuroimaging of small brainstem structures in humans is gaining interest due to their potential importance aging and many clinical conditions. Researchers have used different methods measure activity the locus coeruleus (LC), main noradrenergic nucleus brain. However, extent which these LC localization yield similar results unclear. In present article, we compared four approaches est...

introduction: noradrenergic cells in lc participate in the process of cortical activation and behavioral arousal. the evidence suggests that locus ceoruleus (lc) plays an important role in the sleep-wake cycle. the aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the lc. materials and methods: male wistar rats wei...
