Area of Science:

  • Neuroscience
  • Biophysics
  • Medical Imaging

Background:

  • Nuclear Magnetic Resonance (NMR) equipment utilizes strong static magnetic fields.
  • The interaction of these fields with biological systems, particularly the human brain, is an area of ongoing research.
  • Understanding induced electromagnetic phenomena in the brain is crucial for safety and potential applications.

Purpose of the Study:

  • To investigate the generation of an encephalomagnetic field in the human brain due to exposure to static magnetic fields from NMR equipment.
  • To characterize the frequency of induced currents in coils placed on the cortex.

Main Methods:

  • Exposure of the human brain to static magnetic fields characteristic of NMR equipment.
  • Placement of coils at the cerebral cortex to detect induced currents.

  • Frequency analysis of the detected induced currents.
  • Main Results:

    • A novel encephalomagnetic field is generated in the human brain upon exposure to static magnetic fields.
    • Induced currents in cortical coils demonstrate a distinct frequency range between 6 and 8 Hz.

    Conclusions:

    • Static magnetic fields in NMR equipment can induce measurable encephalomagnetic fields.
    • The identified 6-8 Hz frequency of induced currents may have implications for understanding brain responses to magnetic fields.
