A Closer Look

This nude mouse rests on a caregiver's finger during a health check. "Nude" mice have a genetic change that affects both hair growth and development of the immune system. Because of their reduced immune function, they have been especially important in areas of research where scientists need to…

Checking Each Other Out

Sometimes the observation goes both ways! This research rat stopped to investigate a visitor who was taking a closer look. Rats are naturally curious and use their senses - including smell, touch and their highly sensitive whiskers - to investigate their surroundings. Caregivers also observe research animals regularly,…

Positive reinforcement for bunny checks

These rabbits are involved in research aimed at preventing fluid build-up in the chest, which happens in humans and animals battling certain forms of cancer. These rabbits do not have cancer; but fluid build-up can be simulated in the animals, so that treatment strategies can be developed. Just…

Taking a Dip in the Pool

Monkeys at the Oregon National Primate Research Center are provided with many types of environmental enrichment to simulate a natural environment.  In the summer the monkeys have access to pools and other forms of water enrichment.  Here you can see them enjoying a refreshing dip in their pool.

Monkey Enrichment for Indoor Housing

Monkeys are given enrichment such as toys, swings, climbing structures and other items to increase their behavioral diversity. Many of these objects are rotated on a regular basis, to keep them novel.  This indoor enclosure for the monkeys at Oregon National Primate Research Center provides many opportunities that…

Positive Reinforcement Training for Blood Draw

Garcia is participating in positive reinforcement training (PRT), also known as clicker training. PRT is a type of training in which animals get rewards for performing desired behaviors. Using PRT, monkeys like Garcia voluntarily cooperate with procedures necessary for husbandry and research protocols. Such procedures include entering a…
