Mice were administered the pain test either Individually (IT-individually tested, dominants: n = 9; subordinates: n = 9) (i.e., alone) or as a dyad.— PLoS ONE Alerts: New Articles
The dyad was considered stable when one of the two mice achieved the dominant social rank (i.e., for 3 consecutive days the dominant and subordinate roles did not change).— PLoS ONE Alerts: New Articles
The behavioral response to pain did not differ when animals were tested individually (IT condition) or when only one in a dyad was injected (OI condition) and pain tested.— PLoS ONE Alerts: New Articles
Remarkably, when both mice of a dyad were injected (BI condition), their behavioral response to pain in the formalin test appeared significantly reduced compared to that exhibited when only one animal of a dyad was injected (OI condition).— PLoS ONE Alerts: New Articles
I can tell you that we worked on an earlier generation of the UPS dyad, the electronic device that their drivers used to track their deliveries.— Hartford Courant blogs
