Animals who can hibernate or go to a hibernation-like state are amazing animals. These creatures can significantly reduce both their metabolic rate and drop their body temperature in order to survive in harsh environment conditions and in periods of food shortage. But how is this state of “suspended animation” triggered? Scientists may have figured out the cause of this phenomenon.

Two studies published in the journal Nature have independently zoned in on the brain circuitry that triggers a hibernation-like state in rodents, which they say could have implications for humans.

Although studies have pointed to the central nervous system’s involvement, the precise mechanism for this state has been elusive.
The two studies, which had different methods, both showed that a group of neurons found in the hypothalamus is what causes hibernation-like states in rats.
If humans have similar neurons, [the researchers] speculate this could help control fever or induce hypothermia and slow down metabolism after events like a heart attack or stroke to reduce tissue damage.
