To observe the effects of propofol and dexmedetomidine on expression cytochrome c oxidase in primary hippocampal neurons isolated from neonatal mice. C57 mice were sacrificed within 24 h birth tissue was collected. Primary cultured vitro then randomly divided into a control group (0 μM 0 dexmedetomidine), (20 dexmedetomidine) propofol+dexmedetomidine 10 dexmedetomidine). The incubated for 1 h. ...
The sources of ipsilateral projections from the hippocampal formation, the presubiculum, area 29a-c, and parasubiculum to medial, orbital, and lateral prefrontal cortices were studied with retrograde tracers in 27 rhesus monkeys. Labeled neurons within the hippocampal formation (CA1, CA1', prosubiculum, and subiculum) were found rostrally, although some were noted throughout the entire rostroca...
Purpose: To study the protective effect of oxytocin on hypoxic-ischemic brain neuron injury in neonatal rats, and mechanism action involved.Methods: Hippocampal slices from SD rats were cultured oxygen/glucose-deprived (OGD) solution, leading to establishment model hippocampal vitro. The assigned 3 groups: control (ACSF solution), (OGD solution + 1 μM oxytocin). vertebral neurons CA1 region HIB...
Background and Objective: Deleterious effect of neurotoxins on the brains of animals is an attractive research topic. In this research, the effect of microinjection of colchicine into the hippocampal CA1 was shown by examining the novelty seeking behavior. Also, the effect of pre-injection of galantamine, an effective agent in the treatment and prevention of Alzheimer's disease, for reversal of...
Projections from the hippocampal formation to the medial prefrontal cortex are well known. In this report we used two retrogradely transported tracers to show that a small but significant subpopulation of pyramidal neurons in area CA1 and subiculum of the hippocampal formation projects to the lateral prefrontal cortex. About half of these neurons also possess collateral projections to the media...
In adult mammals, neural progenitors located in the dentate gyrus retain their ability to generate neurons and glia throughout lifetime. In rodents, increased production of new granule neurons is associated with improved memory capacities, while decreased hippocampal neurogenesis results in impaired memory performance in several memory tasks. In mouse models of Alzheimer's disease, neurogenesis...
Seizure-induced damage elicits a loss of hippocampal neurons mediated to a great extent by the p75 neurotrophin receptor (NTR). Proneurotrophins, which are potent apoptosis-inducing ligands for p75(NTR), were increased in the hippocampus, particularly in astrocytes, by pilocarpine-induced seizures; and infusion of anti-pro-NGF dramatically attenuated neuronal loss after seizures. The p75(NTR) i...

In rodents, increased production of new granule neurons is associated with improved memory capacities, while decreased hippocampal neurogenesis results in impaired memory performance in several memory tasks.

Neuropeptide transmitters are synthesized throughout the CNS and play important modulatory roles. After synthesis in the neuronal cell body, it is generally assumed that peptides are transported to nonspecialized sites of release. However, apart from a few cases, this scenario has not been thoroughly examined. Using wild-type and NPY(GFP) transgenic mice, we have studied the subcellular distrib...
The dentate gyrus (DG) plays a crucial role in hippocampal-related memory. The most abundant cellular type in the DG, namely granule neurons, are developmentally generated around postnatal day P6 in mice. Moreover, a unique feature of the DG is the occurrence of adult hippocampal neurogenesis, a process that gives rise to newborn granule neurons throughout life. Adult-born and developmentally g...
