Synchrony
Definition:
(n.) The concurrence of events in time; synchronism.
Example Sentences:

(3) Three areas of abnormality were seen in schizophrenics: first, the interval preceding the motor response was characterized by reduced motor steadiness prior to the button-press response; second, the motor response was made with excessive force (hyperdynamia); and third, the agonist-antagonist synchrony (motor reversal) was impaired.

(5) Satisfactory synchrony was achieved to study S phase events.
(6) After treatment of Chinese hamster cells (line CHO) with various protocols for synchrony induction, the subsequent ability of cells to traverse the cell cycle (i e., to perform, an essential cell cycle process) has been determined by measurement of the DNA distribution pattern among cells in large populations with the Los Alamos flow microfluorometer In the cultures prepared by the various synchronizing techniques the vast majority of cells traversed the cell cycle in a normal fashion; however, in all cultures examined there remained small subpopulations which, though remaining viable for several days, could not carry out normal traverse.
