Abstract
The magnetic field of the action potential from an isolated frog sciatic nerve was measured by a SQUID magnetometer with a novel room-temperature pickup coil. The 1.2 x 10(-10) tesla field was measured 1.3 millimeters from the nerve with a signal-to-noise ratio of 40 to 1.
摘要
用一个带有新型室温拾波线圈的超导量子干涉仪磁力计测量了分离的青蛙坐骨神经动作电位的磁场。在距离神经1.3毫米处测得磁场为1.2×10⁻¹⁰特斯拉，信噪比为40比1。
