Abstract
Photon counts were measured every 15 ms for 75 s from microtubule-enriched preparations (and
nuclei) from mouse melanoma cells during baseline and after 2 min exposures to 1 μT magnetic
fields. The magnetic fields were generated from a circular array of solenoids and presented with
accelerating or decelerating rotation velocities. The range of photon radiant flux density was in
the order of 10

. Microtubules preparations that had been exposed for only 2 min to a
magnetic field configuration corresponding to the electric field pattern that induced long-term
potentiation in neural tissue when applied as electric current displayed peaks of spectral power
densities within 7 - 8 Hz, 9.5 Hz, 14 - 15 Hz, and 22 Hz bands. The major peak (9.4 Hz) bandwidth
was approximately 0.1 Hz. While microtubule preparations exposed for 2 min to a 7 Hz sine-wave
or in the absence of a field emitted an overall similar level of spectral power density, the peaks in
power density were not present. Treatment with the LTP patterned fields, compared to the base-
line or sine-wave fields primarily altered the frequency band in which the amplitude of the photon
field was expressed. These results suggest that the photon emissions from microtubule prepara-
tions have the capacity to respond to specifically-patterned or geometric shapes of magnetic fields
by altering spectral configurations rather than the absolute numbers of photons.
