Aging in mice linked to brain clock changes and weaker rhythms
A study comparing young and aged mice found weaker two- to six-hour cycles in movement and body temperature, alongside changes in the brain’s daily clock.A study comparing young and aged mice found weaker two- to six-hour cycles in movement and body temperature, alongside changes in the brain’s daily clock.

Who was studiedYoung and aged mice, against young mice
What changedAged mice had weaker two- to six-hour rhythms in movement and body temperature than young mice
The catchBrain changes and rhythm changes were not measured in the same mice
