脑电磁图(magnetoencephalograph):起源于脑的同一电流既可产生脑电图,也可在头部产生磁场,称为神经磁场,这种磁场的测量称为脑电磁图。膜电位(membrace potential):细胞膜内外的电位差或跨越细胞膜的电位差,在未受刺激时,细胞内各处几乎是等电位的,细胞外也是等电位的,因此膜电位的值实际上和细胞内及细胞外的电位差相同。当这种差存在时,就说细胞膜处于极化状态。微电极(micro-electrode):通常用直径小于0.01毫米的两个电极放在一个细针头或玻璃管内,此二电极间的距离小于0.1毫
Magnetoencephalograph: The same current originating in the brain produces either an EEG or a magnetic field at the head called a neuromagnetic field. This measurement of a magnetic field is called the electroencephalogram. Membrane potential: the potential difference between the inside and outside of the cell membrane or across the cell membrane, when not stimulated, the cells throughout the almost equipotential, the extracellular is also equipotential, so the value of the membrane potential and The same potential difference between intracellular and extracellular. When this difference exists, the cell membrane is said to be polarized. Micro-electrode (micro-electrode): usually two electrodes with a diameter of less than 0.01 mm in a thin needle or glass tube, the distance between the two electrodes is less than 0.1 milli-square
