As the title asks, what neurological processes occur when we feel revulsion?

By revulsion, I mean the involuntary and voluntary physical and psychological responses far stronger than the aversion discussed in this question to things like, in my case, cockroaches. I assure you, that I am not referring to 'fear' either, I mean a feeling of loathing towards something.

A good way to start answering this question would be to find any journal paper at all on how revulsion is different from fear or aversion--that difference needs to be defined before this question can be answered. – Krysta Jun 28 '13 at 15:48
I remember reading that disgust, even if social or visual, had a lot of overlap in activity patterns with the same circuits involved in physiological nausea. – Keegan Keplinger Jun 28 '13 at 17:20
@KeeganKeplinger that makes sense as that is definitely one of the sensations of 'revulsion'. – user3554 Jun 29 '13 at 4:29
