Effects of visual deprivation on the induction of epileptiform activity were studied in layer II/III of mature rat primary visual cortex. Field potentials were evoked by stimulation of layer IV in slices from control and dark-reared (OR) rats. Picrotoxin (PTX)-induced epileptic activity was characterized by spontaneous and evoked epileptic field potentials (EFPs). The results showed that OR s...

introduction: the hippocampus was recognized as an important focus of epileptic seizures. a long-term potentiation (ltp) like that of epileptiform activities is considered as synaptic which has been observed for the first time in hippocampal formation. the purpose of the present study was investigating the synaptic plasticity induced by tetanic stimulation at ca1 area of the rat hippocampal sli...

This paper presents and evaluates a fast graphics hardwarebased voxelization method to spatial analysis, which generates object-coded volume data utilizing the Performer scene-graph. Two color-coding algorithms are introduced. The first one resolves one object per voxel for a large number of objects. The second algorithm extends the first to identify multiple objects in one voxel, by using blen...

In this study, we propose a model which may assist in diagnosis of (AD) using T1 weighted MRI brain images. The proposed model involves construction of statistical features from multiple trans-axial slices from hippocampus and amygdala regions, which play a significant role in AD diagnosis. Features from multiple slices are then averaged, which resulted into a smaller set of relevant features. ...

objective: the main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. methods: drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [hg], infrared radiation at power levels of 100, 150 and 200 w in the three repetition. resu...
