説明

<jats:p>We have been developing a mice biomagnetic measurement system using a dc superconducting quantum interference device magnetometer for a comparative magnetoencephalogram study of transgenic and wild mice. In this study, we adopted a magnetometer with a pickup coil of 1.0mm diameter and 0.7mm lift-off distance to improve spatial resolution and magnetic field sensitivity. The magnetocardiogram of a wild mouse was measured as the initial application of the system. The bipolar peak positions in a magnetic field map separated by 5.6mm were clearly detected with the maximum amplitude of 88pT.</jats:p>
