Even humans have the non-conscious pain detection/response reflex. When you put your hand on a hot stove, your hand will recoil before the signal is sent to the brain. Your spinal cord initiates the recoiling and then routes the pain sensation up to the brain to punish you for your stupidity. Is that "actual pain"?
I suppose this answers my question. They detect, but don't consciously feel.

People who have lost the ability to feel pain end up injuring themselves terribly during sleep because they lay on it like that for a few hours.
neuro wrote:Maybe the discussion has been too strictly centered on the word "pain" rather than "feel".
In neuroscience, two words are generally used in talking about emotional life: emotion and feeling.
Although this is a schematic "imposition", as it often occurs for scientific jargon, it fulfills the need of knowing what one is talking about. ...
It is of interest that the relation is not one-way only: conscious perception of oneself and one's own experience is able to elicit responses in the lower circuitries and limbic system which precisely reproduce responses to physical pleasure, well-being, distress and pain. This occurs in response to conceptual elaboration of social, affective, esthetic, intellectual experiences. ...
The more developed is system (2), i.e. the more sophisticated is the conscious representation of one's interior life, the more relevant is the "feeling" component generated by biological "emotion".
DaMadScientist wrote:Well it depends what your definition of pain is. If you try to chop off a bugs leg... The nerves will send a message to there brain saying "This is unpleasant get away"! Now the same goes for a human if i try and chop off your leg you would try to get away. So its the same in the sense that information of something negative is being passed to the brain.
Is the pain sensation the same for humans as it is for insects... no. We don't have anything close to the same brain structure so information is processed in very different ways. Pain for you is not the same as pain for me and we are both human. I for example can take a lot of pain, don't bother me, but some women might cry if you pinch her. The pain for a bug might be worse, less, or interpreted as just information without a sensation. Problem is no real way to know unless your the bug!

If that isn't some sort of intelligence than I don't know what it is. Most people can't even give good instructions.
