BIOMAGNETIC NEUROSENSORS .4. DESIGN AND OPTIMIZATION FOR ANALYTICAL USE

Biomagnetic neurosensors based on magnetic stimulation and magnetic de tection 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 predict ed from electromagnetic fundamentals, meaningful analytical measuremen ts using real nerves as molecular recognition elements require additio nal 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 biom agnetic neurosensors in other laboratories.
