You're right! Good job!

Does that mean that you keep the money?

It didn't start with a T, but it has a T in it!

"P" sounds like "T"....

I was going to guess


Vestibular vertigo.

It is where your body relies on your eyes to gain its balance, and when the visual clues are taken away your body cant maintain stability.

I guess all those years of college were wasted on me.

This is interesting to me, as I never considered Proprioception as meaning that, at least with reference to MS. Maybe I have misunderstood all this time though.

Several years ago, I went looking for a description of what it's called when I don't know where my arms are legs are, and I ran across this word/description:

"Proprioceptive Dysfunction = Loss of awareness of location of body parts"

http://www.mult-sclerosis.org/mssymptoms.html

I thought that was the right word, but maybe it's not.

What happens with me, sometimes, is I can be laying on my bed or the couch, and with my eyes closed, I could not tell you which way my leg or arm is laying. It might be right across my body, at my side . . . I have no idea. It's like a brain disconnect that I can't move it either, at least until I open my eyes, locate the limb, and concentrate hard on moving it. I thought this was Proprioceptive dysfunction, but when I look up the "generic" definition . . . I'm not so sure it is correct:

http://en.wikipedia.org/wiki/Proprioception

http://www.mult-sclerosis.org/RombergTest.html

Hmmm ... does this word work for both situations?

BTW, no question is ever "quick" around here. ;-P

I know I'm late but, isn't it *Proprioception*..

Where's my $500??

Cherie, she's not talking about, not knowing where your limbs are, but, about getting disoriented as you enter a dark room.

HEY! Spatial perception was close! I should at least get half!!

Your vestibular system responds to the postion of the head in relation to gravity. Proprioception is the perception of sensory nerve endings in muscles, tendons and joints that provides a sense of the body's position in space ; refers to sensations from the muscles and joints.

If your vestibular system become hypersensitive you may get dizzy very easily. Also if you get dizzy when you shut your eyes you could be low in b12

You are right, I guess. I was thinking proprioception. I guess I just had the wrong definition for it.

No, I think you might be right too . . . I just never thought of it that way. According to that Wiki site I posted:

"Proprioception is tested by American police officers using the field sobriety test where the subject is required to touch his or her nose with eyes closed. People with normal proprioception may make an error of no more than 20 millimetres. People suffering from impaired proprioception (a symptom of moderate to severe alcohol intoxication) fail this test due to difficulty locating their limbs in space relative to their noses."

"Proprioception is what allows someone to learn to walk in complete darkness without losing balance. During the learning of any new skill, sport, or art, it is usually necessary to become familiar with some proprioceptive tasks specific to that activity."

Based on that . . . I'm guessing, but it may be proprioception that could cause a person to not be able to balance in the dark too. I've just never thought of it that way.

OR . . . maybe what I have is something different.
