The sedative effect of dexmedetomidine is probably mediated by the activation of presynaptic a-2 adrenoreceptors in the locus coeruleus, leading to inhibition of release of norepinephrine, along with it, inhibition of adenylate cyclase may lead to hypnotic response.
Our results suggest that targeting locus coeruleus system hyperactivity with new pharmacological or psychotherapeutic interventions are approaches worthy of further investigation, said Dr.
En etapa III, Se produce un aumento de los ovillos neurofibrilares, se encuentran en toda la region frontal superior, frontal dorsolateral, inferior orbital, septal, insular, polo temporal, medio superior y cortezas parietales y temporales inferiores, en el hipocampo, corteza entorrinal, la amigdala, nucleo basal de Meynert y locus coeruleus.
5,6) Whereas in AD the most striking neuronal loss and gliosis is in the entorhinal cortex and hippocampus, nucleus basalis, locus coeruleus, and neocortex, neuronal loss and gliosis in FTLD generally parallels the gross atrophy.
Estos receptores, especificamente los TAR-1, TAR-2 y TAR-5, estan presentes en la amigdala y los TAR-1 y TAR-2 se expresan, ademas, en areas que median el umbral del dolor como el locus coeruleus, el nucleo dorsal del rafe y el area tegmental ventral [20].
Ce neuromodulateur est libere au niveau du tronc cerebral dans une region appelee le locus coeruleus (LC).
Effect of locus coeruleus stimulation on the development of kindled seizures.
Serotoninergic cell bodies located in the raphe nucleus in the brainstem, and noradrenergic neurones located in the locus coeruleus (also in the brainstem) send projections to various parts of the brain involved in the control of mood, appetite, sexual activity, attention and concentration.
Because the major source of noradrenaline is neurons in an area of the brain called the locus coeruleus, the UIC researchers hypothesized that damage to the LC was responsible for lowered levels of noradrenaline in the brains of MS patients.
The mechanism of action of VNS remains uncertain, but the possibilities include arousal of the reticular formation; stimulation of locus coeruleus and noradrenaline pathways; changes in a neurotransmitter, amino acid, or neuropeptide; or indirect thalamus stimulation, Dr.
45) The locus coeruleus is the sole source of noradrenergic innervation to the cortex.
El origen del sistema serotoninergico cerebral son las neuronas de los nucleos de rafe, cuyas proyecciones llegan a casi todas las demas regiones encefalicas, siendo locus coeruleus, hipocampo, amigdala y cortex frontal quiza las mas importantes en su papel regulador de la ansiedad (dos Santos, de Andrade & Zangrossi, 2008; Holmes, 2008; Molodtsova, 2008; Pum, Huston & Muller, 2009).
