Monkey in imaging
Imaging technologies have greatly reduced the number of animals needed for research. In the past, animals would have had to be euthanized in order to examine internal organs while today imaging allows visualization and study of what was previously not possible. Here an anesthetized marmoset monkey is being prepared to enter the MRI as part of a study to understand the link between energy metabolism and neural function. Basic research like this provides a foundation for future medical innovations to treat many serious age-related diseases.(Photo credit: Wisconsin National Primate Research Center)
