Filbert the mouse lemur


Weighing a little less than two cubes of sugar when he was born at the Duke Lemur Center in June 2013, male mouse lemur Filbert is one of more than 40 grey mouse lemurs living at Duke. If all goes well, Filbert could live to be 10-15 years old in captivity. Grey mouse lemurs are nocturnal animals that develop dementia-like symptoms similar to human Alzheimer’s as they age. Because they are a closer genetic match to humans than mice or rats are, researchers at the Duke Lemur Center hope that non-invasive research on these tiny primate cousins will lead to a better understanding of the aging brain.
