EXPERIMENTAL CONDITION - ANNOTATIONS

The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Definition:The portion of a controlled light/dark cycle in which the subject is not being exposed to ambient light (that is, during which the room is darkened). A controlled light/dark cycle is a recurring series of conditions in which an organism experiences successive periods of exposure to controlled ambient light followed by exposure to darkness, the lack of such light, which is in turn followed by exposure to controlled ambient light and so forth.
