The effect of continuous exposure to low frequency electric fields on three generations of mice: A pilot study

Summary Mice were allowed to mate, gestate, deliver and rear their offspring for 3 successive generations while being continuously exposed to 60 Hz electric fields. Mice exposed to vertical electric fields exhibited decreased body weights at 35 days postpartum and increased mortality, rates for 3 successive generations. Mice exposed to horizontal electric fields exhibited decreased body weights for 2 successive generations.Supported by grants from National Institute of Health, and the Veterans Administration. Research Service, No. 0865-01.Vibration measurements were performed by Dr.Daniel A. Driscoll, New York State Department of Environmental Conservation.     

Effects from the pyramidal tract on primary afferents and on spinal reflex actions to primary afferents

Zusammenfassung Es konnte gezeigt werden, dass Überleitungen in spinalen Reflexsystemen, die für die präsynaptische Depolarisation gewisser primärer Afferenzen verantwortlich sind, von der sensorisch-motorischen Grosshirnrinde über die Pyramidenbahn gefördert werden kann.     

Presynaptic inhibition in the lumbar cord evoked from the brain stem

Zusammenfassung Es wird gezeigt, dass eine elektrische Medulla oblongata- oder Pons(kaudal)-Stimulation eine Depolarisation (präsynaptische Inhibition) von Ia-, Ib-und Flexor-Reflex-Afferenz im Lumbalmark verursachen kann.
