Heart contains a variety of neurons known to influence cardiac functions. Little is known about the neurochemistry of these neurons. In this study, neurochemistry of intra cardiac neurons of the intrinsic cardiac ganglia was investigated. The technique used allows studying the morphology of the ganglionated nerve plexus found within the atria and great cardiac vessels as well as of individual n...

Glutamate induces excitotoxic damage to hippocampal pyramidal neurons in Status Epilepticus (SE) and epilepsy. In this study, we investigated time course of dysregulation of calcium homeostasis at various intervals after an episode of SE in acutely isolated CA1hippocampal pyramidal. For this purpose, male Sprague-Dawley rats (200 g) were subjected to pilocarpine-induced SE. The SE was blocked a...

introduction cholinergic system is one of the important systems of mammalian cns. cholinergic neurons distributed in brain and spinal cord and contributed to principal functions like: consciousness, learning and memory, and motor control. in this study we investigated the differentiation potentiality of mouse embryonic stem cells toward cholinergic neurons. the aim of this study was to evaluate...

the effects of formalin as a peripheral noxious stimulus on the activity of lateral paragigantocellularis nucleus (lpgi) neurons were examined. spontaneous activity oflpgi neurons was recorded after confirmation of their responsiveness to acute pain, and thereafter formalin (50 µl, 2.5%) was injected in the contralateral hindpaw. the response of the lpgi neurons was monitored for 60 min. a biph...

introduction: the present study evaluated morphological changes of ca1 hippocampal neurons following transient bilateral common carotid and permanent left middle cerebral arteries occlusion, also the neuroprotective effects of aspirin i.p injection was inducing assessed after ischemia in male rat. material and methods: in this experiment, 4 groups of animals were used including; control, sham, ...

introduction: neurotrophins, as a family of proteins, are responsible for induction of the survival, development, and function of neurons. also, neurotropic factors are growth factors like neurotrophins that help neurons survive. moreover, neurotrophins differentiate between progenitor cells so that neurons are formed. despite the fact that the majority of mammalian brain neurons are produced p...

This study has examined the functional importance of nucleus accumbens (NAc)-ventral tegmental area (VTA) interactions. As it is known, this interaction is important in associative reward processes. Under urethane anesthesia, extracellular single unit recordings of the shell sub-region of the nucleus accumbens (NAcSh) neurons were employed to determine the functional contributions of the VTA to...

Objective(s): To reach an evidence-based knowledge in the context of the temporal-spatial pattern of neuronal death and find appropriate time of intervention in order to preserve spared neurons and promote regeneration after traumatic spinal cord injury (TSCI). Materials and Methods: The study design was based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided...
