- This fact has come to be known as the Dehnel phenomenon.
- It affects not only the brain, but also other major organs such as the liver and kidneys.
- This factor explains why such small animals can survive harsh winters with associated reduction in food availability.
- The phenomenon may be responsible for the preservation of certain rare populations such as the Suisun Shrew.
