Why These Squirrels Destroy Their Brains Every Winter

TL;DR

Hibernating ground squirrels deconstruct and rebuild their brains every 2-3 weeks during winter, showcasing remarkable neural plasticity.

Transcript

[ ♪ Intro ] We tend to think of our brains, at least by adulthood, as being pretty static. There will be some changes, but for the most part, the large structural shifts are over. But that’s not the case with hibernating ground squirrels. Several species actually deconstruct part of their brains, only to rebuild them again. And they don’t just do i... Read More

Questions & Answers

Q: Why do hibernating ground squirrels deconstruct and rebuild their brains every 2-3 weeks?

Hibernating squirrels undergo this neural construction to save energy and adapt to the extreme temperature changes during their hibernation cycles.

Q: How do hibernating squirrels exhibit impressive synaptic plasticity compared to non-hibernating animals?

Hibernating squirrels can regrow their brain structures in just hours, a process that takes months in rats, showcasing unparalleled neural adaptability.

Q: What potential applications do scientists see in studying hibernating squirrels' brain rebuilding abilities for human diseases?

Researchers believe that understanding and potentially mimicking the neural plasticity of hibernating squirrels could offer insights into treating human diseases like strokes.

Summary & Key Takeaways

• Ground squirrels hibernate in cycles, deconstructing and rebuilding their brains every 2-3 weeks to save energy.

• During hibernation, squirrel brains shrink, but quickly re-grow when they wake up, a process known as synaptic plasticity.

• The ability of hibernating squirrels to rapidly rebuild their brains intrigues scientists for potential human application.
