Background and Objectives: Studies have documented the morhplogical, neurochemical and functional difference between the dorsal and ventral zones of hippocampus. The aim of this study was to assess the effects of chronic diabetes mellitus type1 on ventral and dorsal zones of hippocampus. Methods: Experimental diabetes was induced by stereptozotocin at a dose of 60 mg/kg. At the end of 8 wee...

In rats, some parvocellular paraventricular neurons project to spinal autonomic centers. Using the virus tracing technique, we have demonstrated that magnocellular neurons, but not supraoptic also preganglionic centers of mammary gland, gingiva, or lip. A part these has shown oxytocin immunoreactivity. present experiment, examined whether same neuron sends fibers retina eye projects posterior p...

A memristor is a nonlinear two-terminal electrical element that incorporates memory features and nanoscale properties, enabling us to design very high-density artificial neural networks. To enhance the property, we should use mathematical frameworks like fractional calculus, which capable of doing so. Here, first present fractional-order synapse-coupling Hopfield network on two neurons then ext...

• Orai1 was suggested to amplify dendritic spine Ca 2+ signals. However, Orai2 more abundant than in spines of hippocampal neurons. Roles and Orai3 neurons were not addressed. The contribution IP 3 -dependent release considered. channels reported as critical contributors the signal underlying synaptic plasticity associated with learning memory. We discuss results view conflicting other reports ...

introduction: although aging is the most important risk factor for alzheimer's disease (ad), there is evidence indicating that neuroinflammation may contribute to the development and progression of the disease. several studies indicated that minocycline may exert neuroprotective effects in rodent models of neurodegenerative diseases. nevertheless, there are also other studies implying that...

• Midbrain dopaminergic neuron transcription factors modulate the long-term survival and maintenance of these neurons. Understanding developmental pathways might lead to a better insight into their degeneration in Parkinson's disease. Phylogenetic profiling was used identify molecular interactions correlated with factors. Two distinct evolutionary pathways, pertaining early late novel links wer...

Abstract In the brain, information is encoded, transmitted and used to inform behaviour at level of timing action potentials distributed over population neurons. To implement neural-like systems in silico, emulate neural function, interface successfully with neuromorphic circuits need encode a way compatible that by populations neuron brain. facilitate cross-talk between engineering neuroscienc...

Background: Curcumin is the most active ingredient in turmeric root of Curcuma longa of the Zingiberaceae family and has a potent antioxidant activity. This study aimed at investigating the effects of curcumin with various doses on the density of dark neurons in the hippocampus of induced D-galactose aging mice model. This experimental study was conducted on 40 adult male BALB/c mice.  Materia...

Objective(s):This study was carried out to evaluate the effect of maternal morphine exposure during gestational and lactation period on pyramidal neurons of hippocampus in 18 and 32 day mice offspring. Materials and Methods: Thirty female mice were randomly allocated into cases and controls. In case group, animals received morphinesulfate 10 mg/kg.body weight intraperitoneally during 7 days bef...
