Routing is one of the basic parts of a message passing multiprocessor system. The routing procedure has a great impact on the efficiency of a system. Neural algorithms that are currently in use for computer networks require a large number of neurons. If a specific topology of a multiprocessor network is considered, the number of neurons can be reduced. In this paper a new recurrent neural ne...

introduction: many studies have shown that amygdala kindling produces synaptic potentiation by induction of changes in the neuronal electrophysiological properties and inward currents both in epileptic focus and in the areas which are in connection with the epileptic focus and have important role in seizure development and progression such as hippocampal ca1 region. however, cellular mechanisms...

In this paper, I propose an efficient method of identifying important neurons that are related to object’s concepts by mainly considering the relationship between these and their object concept or class. first quantify activation values among neurons, based on which histograms each neuron generated. Then, obtained clustered identify neurons’ importance. A network-wide holistic approach is also ...

HIGHLIGHTS The input GHI variable increased the prediction accuracy of ANN models in 10%. meteorological variables do not influence errors statistically. ANNs with 10 neurons demonstrated lower than those 30 and 60 neurons. one hidden layer showed similar or higher two layers.

Leucokinins (LKs) constitute a family of neuropeptides identified in numerous insects and many other invertebrates. LKs act on G-protein-coupled receptors that display only distant relations to known receptors. In adult Drosophila, 26 neurons/neurosecretory cells three main types express LK. The four brain interneurons are two types, these implicated several important functions the fly’s behavi...

Background and Objective: Parkinson's disease (PD) is characterized by a progressive loss of dopaminergic neurons in substantia nigra. In recent years, there have been interests in the role of the free radical damage in PD. Cinnamon and its derivative, cinnamaldehyde acts as powerful antioxidant and anti-inflammatory agents. This research focused on the effects of cinnamon extract and cinnamald...

Objective(s): Despite effective anticancer effects, the use of doxorubicin (DOX) is hindered due to its cardio and neurotoxicity. The neuroprotective effect of adrenomedullin (AM) was shown in several studies. The present study aimed to evaluate the possible protective effects of AM against DOX-induced toxicity in dorsal root ganglia (DRGs) neurons. M...

Introduction: Memantine (MEM) is a noncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonist clinically used for the treatment of Alzheimer disease (AD) in mild to severe conditions. The present study was conducted to investigate the effects of memantine on the spontaneous firing frequency of CA1 pyramidal neurons in rats caused by an electrical lesion of Nucleus Basalis Magnocellularis (...

Shamsi zadeh MSc Received: 17/09/06 Sent for Revision: 13/03/07 Received Revised Manuscript: 13/06/07 Accepted: 27/06/07 Background and Objective: Seretonergic pathway is one of the neu...

Objective(s): The stimulation of neural stem cells (NSCs) differentiation into neurons has attracted great attention in management of neurodegenerative disease and traumatic brain injury. It has been reported that selegiline could enhance the morphologic differentiation of embryonic stem cells. Therefore this study aimed to investigate the effects of selegiline on NSCs differentiation with focu...
