TL;DR
Albino laboratory rats that were given free access to running wheels while maintained on a 12:12 h L:D schedule were observed to display marked increases in day cycle activity following an unusually intense geomagnetic storm.
Abstract
Albino laboratory rats that were given free access to running wheels while maintained on a 12:12 h L:D schedule were observed to display marked increases in day cycle activity following an unusually intense geomagnetic storm. The activity changes were not immediate but peaked one day to several days after the storm. Two less intense geomagnetic storm conditions during the 51 day observation period were associated with less marked activity increases. Ambient room temperature fluctuations were not significantly correlated with either geomagnetic activity or day cycle activity measures.
