[An analysis of the biological rhythms of pain sensitivity in mice during thermal stimulation]
1Pavlov Institute of Physiology, Russian Acad. Sci., St. Petersburg, Russia.
Abstract:
Circadian oscillations of the 8-hr rhythmic components in nociceptive sensitivity were found in mice. A 12-hr rhythm was close to a sinusoidal one. Circadian waves of the pain threshold were asymmetric and the highest in the middle of the light phase, about 16 hrs. The group rhythms of nociceptive sensitivity appeared to be a result of synchronised separate rhythms.
