Objective
The current study aims to investigate functional brain network representations during the early period of epileptogenesis.
Methods
Eighteen rats with the intrahippocampal kainate model of mesial temporal lobe epilepsy were used for this experiment. Functional magnetic resonance imaging (fMRI) measurements were made 1 week after status epilepticus, followed by 2–4‐month electrophysiological...
The effect of femtosecond laser irradiation in air and in O 2 and CF 4 gas flows on the wettability of electrospun poly(ɛ-caprolactone) fiber tissue scaffolds was studied. Laser power, focus spot size, raster scan spacing and gas atmosphere were varied in experiments. SEM imaging showed the average fiber diameter and surface porosity sizes were both altered by ablation. The micro-scale...
This paper used the finite element method to analyze the cerebrovascular bifurcation. By comparison, we constructed two intracranial artery bifurcation vessel models with different angles, and considered different model how to influence vascular blood flow based on the basic principles of hemodynamics. Through experiment, we mainly computed the value of blood velocity and wall pressure, and compared...
Based on the intracranial artery bifurcation vessel model with different shape, using the finite element method and the basic principles of hemodynamics, we considered the geometry of the vessel how to influence vascular blood flow. Through experiment, we mainly analyzed the value of blood velocity and wall pressure, and compared the difference of hemodynamic parameters in Y-shaped and T-shaped tube...
A novel optical voltage sensor for ultra-high voltage measurement is proposed in this paper. The sensor is based on the converse piezoelectric effect of quartz. The piezoelectric deformation of the quartz crystal induced by an applied alternating voltage is sensed by an electrophotonic detector. To measure the small piezoelectric deformation, an optical-beam-deflection method is presented and the...
