This paper introduces a computational model of integrated information in bidirectional neuron–astrocyte communication. Dynamical analysis and transfer process are studied when stimulation metabotropic glutamate is loaded into neuron astrocyte coupled model, respectively. The results show that the loading stimulus coupling strength cause neuronal hyper-excitation, which some way linked to epilep...

A new neuron network model, as an assistance of image perception, is proposed in this paper. It is based on the retina. And it is shown that this neuron network model can both describe the transfer property of retina well and neglect subordinate details when processing an image. Specially, we also describe how to implement this model and make some experiments on it. Key-Words: Image Perception,...

objective(s):silver nanoparticles (ag-nps) are used widely in bedding, water purification, tooth paste and toys. these nanoparticles can enter into the body and move into the hippocampus. the aim of this study was to investigate the neurotoxicity of silver nanoparticles in the adult rat hippocampus. materials and methods:12 male wistar rats were randomly divided into two experimental and contro...

In terms of the Informax principle, and the input–output relationship of the integrate-and-(re (IF) model, IF neuron learning rules are developed and applied to blind separation tasks. c © 2002 Published by Elsevier Science B.V.

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...
