more cool things my brain can do

So I know that the brain isn't really great at touch localization on certain body parts in relation to others due to the differing representation of body parts in the humunculous down the center part of the brain (ie we are much better at localizing touch to our hands than touch to our backs or something). But something we should get credit for I think is that imazing cortex (I can't remember which... really I am often am a failure of a neuroscience student) involved in three-dimensional representation of the world. For instance, I can close my eyes and touch accurately all of my body parts without making a mistake, even the fine tuning on my face. If you asked me to touch somebody else's nose you'd get a pin the tail on the donkey problem, but my 3D localization is tied up with my body sense, so I'm so much better at proprioception or whatever it's called than I am at knowing where your body parts are.

Just one more reason our brains are amazing.

haha bureaucracy

Quote from my hazardous chemicals training for work. Shock value, anyone? :-P
" Note: When handling toxic materials that penetrate the skin, the proper glove is critical. A researcher died from skin exposure to dimethyl mercury."
