This is Olivia from period 7. If Matsuka Uchikashi "hibernated" is it possible for humans to have that little part of the brain that makes arctic ground squirrles?

Arctic Ground Squirrels

This is Keith and Matt from 7th period. How can Ground Squirrels be able to sleep "hibernate" and if a sound or some sort of distraction is made how don't they wake up and react. Also why their heart beat gets slower and slower how is this possible with them alive still?

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Keith and Matt,
When I was in Fairbanks, I got to see and hold hibernating arctic ground squirrels that were kept in a lab. After about 20 minutes of handling, the squirrels were starting to show signs of waking up so we put them back into their cold, lab burrow. So with enough stimulation they would wake up, but their natural hibernation spot is in a burrow underground so I wouldn't think it is particularly noisy down there.
Hibernation is a state of metabolic depression and some species have evolved the ability to do this. All of their body functions slow down so the requirements for oxygen, warmth, and nutrition are much below normal active levels and they are able to endure this state. It is a survival mechanism to conserve energy during a time when inadequate food is present.

If the squirrel woke up would

If the squirrel woke up would it say awake or go back into hibernation?

Will and Noah,
During hibernation, every two to three weeks the squirrel shivers itself
back to its normal temperature which it maintains for 12 to 15 hours
before going back into popsicle mode. So to answer your question, if it
woke up, it would go back into hibernation unless it was coming out of
hibernation for the season.

this is marty beck from 7th

this is marty beck from 7th period i was wondering if the squreels woke up from hibernation early would they die if so why.

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Marty,
No. They would most likely just go back into hibernation.

Would they be Damaged?

Hi Mrs. Mcneal, so while the squirrels are sleeping if they were woken up before the end of their hibernation, would they become mentally or physically damaged like a sleepwalker would if they were woken up? Thank you! -Brooke S. and Cameron T. from 7th period

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Brooke and Cameron,
I don't think so. If given the chance they would just go back into hibernation. The idea that waking a sleepwalker could cause their death or other damage is a myth.

If that Japanese guy

If that Japanese guy actually did hibernate does that that mean that humans have similar brain properties. Jonathan ingles period 7

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Jonathen,
That is the thought. Hey! You just asked a great question that could be the starting point for new investigation and experimentation! :)

How did Matsutake Uchikoshi

How did Matsutake Uchikoshi go without food, water, and not going to the bathroom for 24 days, and just wake up like hardly anything happened?
period 7

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Skylar and Christian,
Well if you aren't taking in food and water then you don't need to go to the bathroom either, right? He didn't just wake up like hardly anything happened. Uchikoshi was treated for severe hypothermia, multiple organ failure and blood loss from his fall. It isn't understood how he did this which is what makes it so fascinating!

how was he able to recover

how was he able to recover 100% after every one of his organs failed?

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

I assume you are talking about Mitsutaka Uchikoshi? His organs didn't fail. His organs slowed and his brain was protected. It is not completely understood how he survived this, which is what makes it so fascinating!

This is Ryan and Angelica

This is Ryan and Angelica from per. 7. How much do the squirrels eat when they wake up from hibernation?

Re: [PolarTREC] February 11, 2014 Sleepy Time for Arctic Ground

Ryan and Angelica,
The squirrels basically eat non-stop when they are not hibernating. So that eat and eat and eat and eat. That's their job when they aren't hibernating. A lot of eating.

since humans and animals are

since humans and animals are both mammals why cant we find a way to hibernate like the ground squrriels?.

We have adapted to different environments. The many species of mammals have evolved to a variety of environments and are different even though we share characteristics as mammals. We also can't pick things up with our trunks, hang by our tails or use our teeth to dig tunnels underground. Most mammals don't hibernate. Humans evolved on the African savannah where there was no need to endure a long cold season. Could we find a way after learning from this research? After all, it seems kind of like a coma and humans survive comas (although often with brain damage)? Perhaps, but I doubt it. We are good at other things. Like being highly intelligent.
