Bioelectromagnetism

  • Cells in the nervous system communicate with one another by means of electric signals
  • When there are bioelectric fields there are also biomagnetic fields, and vice versa - Maxwell's equations
  • Bioelectromagnetism - Measurement of an electric or a magnetic field from a bio source
  • Bioelectric signals - directly measured with simple electrodes
  • Biomagnetic signals - Can be detected only with a magnetometer (expensive)
