Summary:
The ground squirrel and the Syrian hamster, two rodents that hibernate in the winter, do not feel cold in the same way as non-hibernators, such as rats or mice. Researchers have discovered that hibernating rodents evolved cold-sensing neurons with diminished ability to detect temperatures below 20 degrees Celsius.
