在构造格林函数并求解界面圆孔对SH波散射及其近场解答的基础上,继续研究该问题的散射远场,给出了散射波远场位移模式和散射截面的解答。
Recording and application of field potentials in amygdala;
杏仁核脑片场电位的记录及其应用
The electrical signals were recorded from the areas of the heart adhering to the 60 MEA electrodes, being called field potentials (FPs).
我们用微电极矩阵记录与60个电极相接触的心肌细胞的电活动(细胞外记录),称为场电位(field potentials,FPs),并与全细胞膜片钳记录的动作电位(action potentials,APs)(细胞内记录)进行比较,发现心房、心室处场电位形态类似于负向的细胞动作电位,场电位时程亦与动作电位时程类似。
The experimental results showed that during the recording of field potentials in the hippocampal CA1 region of anesthetized rats, upward and downward movements of the recording probe for a distance of 2.
实验结果表明,在麻醉大鼠海马CA1区场电位记录中,上下移动记录微电极200μm,对于正向和反向诱发电位的记录几乎没有影响,说明,线性微电极阵列对于神经细胞的损伤很小,检测性能稳定。
Objective:To study the field potentials(FPs) of rats cardiac tissues,and compare both FPs and impulse propagation in atrial and ventricular tissue slices.
目的:应用微电极阵列(MEAs)标测技术研究大鼠心脏组织场电位(FPs)特性,比较心房和心室组织片场电位特性及电激动的传导。
Methods The extracellular recording technique in vivo was used to record the CA3 region field potentials.
方法应用在体电生理细胞外记录技术记录大鼠海马CA3区场电位,用HPLC荧光检测技术测定海马组织氨基酸含量,观察CA3区局部微量给予ZD7288和CsCl后对低频(0·5 Hz)刺激穿通通路(perforant pathway,PP)诱发的海马CA3区群峰电位(population spike,PS)幅度及海马组织氨基酸含量的影响。
