Multiparameter Data Acquisition Systems for Studies of Circadian Rhythms

摘要

Long-term, simultaneous monitoring of multiple metabolic circadian cycles such as energy metabolism, animal activity, and body temperature together have revealed ultradian fine-structure rhythms which are dependent on circadian phase and the perturbations of environmental influences. Because of the variation between individual animals, these experiments need to have large sample sizes for each experimental condition. To this end we have designed, constructed and used four microcomputer controlled data acquisition systems to collect circadian data from individually housed rats and mice. 11 refs., 6 figs.
