Biological Miracle – Wood Frog

Now I'm wondering all kinds of things about their brain. Are they capable of forming memories, and would they retain those memories after a freeze/thaw cycle?

Effectively they're dead when they freeze. I'm assuming there's no brain activity.. Which means when they thaw they're being restored to life. I wonder if any other animals experience this

Reading about them, it seems they migrate in winter (like half a mile uphill), but the adults always return to the same breeding pond in spring, so that information is stored somewhere.

Couldn't it just be algorithmic? Go uphill in the summer, then downhill until you hit water, you'll probably end in the same pond?
