Where in your body is [心]{こころ} located?
When people refer to [心]{こころ} do they refer to their heart or brain? I assume heart as the literal translation, but I've heard both so was wondering what the answer is.
For example, there is the expression [心]{こころ}に[浮]{う}かぶ which seems to me like it would be referring to your brain rather than your heart, is there a distinction between this usage and other usages?
CLARIFICATION
I realize the [心]{しん} can refer to your heart, as in [心臓]{しんぞう}. However, my question is about the word こころ not しん.

where 心 isis my question. – Jesse Good Jul 31 '12 at 1:01
