Where am I?

About once or twice a week, I listen to a Radiolab episode with my morning coffee.  I found this one, on proprioception, particularly interesting. 

What is proprioception?  Basically it refers to your body’s ability to figure out where it is in space - something crucial for those of us who like to move about!  Contributors include Oliver Sacks and Robert Sapolsky (in whose lab my husband is a postdoctoral fellow!).
