Electromagnetic field effects in nerve tissue

In the present work, an attempt has been made to produce structural alterations in tissue from the nervous system of bullfrogs by means of a high-intensity electric field. The electric field used to expose the tissue was compased of a train of high-intensity, short-duration pulses. Theses pulses provide a high electric-field intensity in the tissue, yet a low enough absorbed-energy density to cause negligible thermal heating. Exposed and control tissue prepared for light microscope investigation was stained with thionin and hematoxylin and eosin stains. No gross histological alterations of the large motor neurons of the exposed tissue were found when compared with the control tissue.
