Abstract
Biomagnetic neurosensors based on magnetic stimulation and magnetic detection of neural events depend critically upon the effective matching of the magnetic transducers and the neural tissue employed. Although the properties of wire-wrapped ferrite core transducers can be predicted from electromagnetic fundamentals, meaningful analytical measurements using real nerves as molecular recognition elements require additional calibration and optimization steps in order to achieve good system response and lifetimes. This note provides some design guidelines and experimental test procedures to enable potential users to employ biomagnetic neurosensors in other laboratories.
