In 2006, a 12-year-old female chimpanzee named Annie from the University of California, Davis' primate center was paralyzed from the neck down after a spinal stroke. She was not expected to survive.

But scientists weren't ready to give up on her. They created a custom touch screen that allowed Annie to control her movements. The touch screen was placed in front of her on a cart, and she could use her fingers to communicate with the scientists.

The scientists used a variety of methods to teach Annie how to use the touch screen. They used positive reinforcement, such as giving her treats when she successfully completed a task. They also used repetition and practice, so that she would eventually become proficient at using the touch screen.

After several months of training, Annie was able to use the touch screen to move her arms and legs. She was able to feed herself, drink water, and even walk. The scientists also created a game on the touch screen that helped her to improve her memory.

Annie's recovery was a miracle, and it showed that even in the face of paralysis, there is still hope for recovery. The touch screen gave her the ability to communicate with her scientists and to move her body. It also gave her a new sense of independence and freedom.

In 2019, Annie passed away at the age of 34. She was survived by her sons, grandchildren, and a legacy of hope for other paralyzed animals.
