Effects of bilateral lesion of the locus coeruleus on the sleep-wake cycle in the rat
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 we...
متن کاملlocus coeruleus lesions and pcos: role of the central and peripheral sympathetic nervous system in the ovarian function of rat
abstract background: “polycystic ovary syndrome (pcos) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction”. “autonomic and central nervous systems play important roles in the regulation of ovarian physiology”. the noradrenergic nucleus locus coeruleus (lc) plays a central role in the regulation of the sympathetic nervous system and synaptically connected to the ...
متن کاملDescending modulation of visceral nociceptive transmission from the locus coeruleus/subcoeruleus in the rat.
The purpose of the present investigation was to examine whether electrical stimulation in the locus coeruleus/subcoeruleus (LC/SC) could modulate visceral pain evoked by noxious colorectal distention (CRD). Experiments were performed on 40 pentobarbital anesthetized male Sprague-Dawley rats. Extracellular potentials of single L(6)-S(2) spinal neuron were recorded with a carbon filament electrod...
متن کاملThe Protective Effect of Vitamin E on Locus Coeruleus in Early Model of Parkinson\'s Disease in Rat: Immunoreactivity Evidence
Background: Free radical formation and oxidative stress might play an important role in the pathogenesis of Parkinson's disease (PD). In vitro data indicate that neuromelanin (NM) pigment is formed the excess cytosolic catecholamine that is not accumulated into synaptic vesicles via the vesicular monoamine transporter 2 (VMAT2). We designed this study to investigate the neuroprotective effects ...
متن کاملAdenosine decreases action potential duration by modulation of A-current in rat locus coeruleus neurons.
The possibility that adenosine modulates voltage-dependent conductances in locus coeruleus neurons was investigated in current-clamp and voltage-clamp experiments in a totally submerged rat brain slice preparation. Adenosine (100 microM) reduced the duration of control action potentials and action potentials prolonged by 1 mM barium. Adenosine (100 microM) also reduced the amplitude and slightl...
