Video Backyard Brains Can Help Satisfy Your Inner Frankenstein (Video) 199

Video no longer available.
Did you know that cockroaches have such large nerves in their legs that you can poke into their legs almost at random and hit a nerve with an electrode so you can stimulate that leg with hip-hop music and and watch it move? And that you can easily order the parts to do this at home or at school? You can. And supplies to perform many other neuroscience experiments, too. Amaze your friends! Learn how neurons work! Gross out squeamish people! All that (and more) is what Backyard Brains is about.

      That's what I thought, but they cut off the leg (not do it on the cockroach), use juvenile cockroaches that can grow their legs back, and they anesthetize the roach with icewater first.

        That's a pretty weak defense against a claim of cruelty. A human analogue: Suppose you need a bunch of healthy teeth for an experiment. Find a child and yank out a few teeth - they'll grow new ones eventually. Shoot them up full of Novocaine first and they won't even feel it. I assume no one thinks that's acceptable?

        If you're ok with the process because it's only a cockroach, just admit that. Don't try to use some false justification to convince yourself that you were humane about cutting it's leg off.

This suggests that they still have some sort of elementary reception of noxious stimuli, and their bodies release chemicals to dull sensations of pain. While no, its most likely not the sensation humans are used to, it is still a negative sensation that should be minimized.

If you were in a cockroach body you would have limited senses and physical abilities, so even if you feel horror and misery how would you prove it to some human?

      If you stuck a venus fly trap for the same purpose, or you stabbed a maple tree for the purpose of making it bleed, is that also cruel? Practically everyone can see that it is cruel to do this to a human, while practically everyone can see it is not cruel to do this to do it to a plant. Somewhere between these, we went from cruel to not cruel. Is there a line, on one side of which is cruel, and on the other is not cruel, or is there a spectrum of cruelty here? And what property of these "creatures" makes it crueler to do so to some, than to others?

      • The line is: Plant vs Animal. It's really not that hard. Animals have this central processing unit that allows the feeling of pain. We call it a brain. Plants, to the best of our knowledge, feel no pain.

          That's actually not true at all. Pain is carried by nociceptors, which are found in higher orders. Insects have not been demonstrated to have nociceptors. They "feel" noxious stimuli. But they don't process noxious stimuli as "pain". They process it as a feeling, and something they want to get away from. But their nervous system doesn't process it as an "unpleasant" stimulus. Just a stimulus that might possibly kill them, so they should flee the stimulus.

          By your argument a neural network running on my computer also feels "pain" and our collective computer systems are the worst set of torturers to have ever existed.

      • by satuon ( 1822492 )

        Well, a plant doesn't have a nervous system so it can't feel pain. Insects have a nervous system so they probably feel pain, but then, their nervous system is so simple I doubt their pain has any meaning.

        • My point is that more is required to feel pain than "has neurons", or even "has a nervous system". A crucial part of the human experience of pain involves nociceptors which cockroaches do not have, for example. My point from the beginning is that revulsion from perceived cruelty in prodding cockroaches in this way is due to anthropomorphizing cockroaches and not any actual cruelty.

          Based on the modding, here, it looks like actual scientific data still takes a back seat to intuition.

          • by satuon ( 1822492 )

            I actually was agreeing with you. That's why I said I doubt their pain has any meaning. To elaborate, if a computer has a thermal sensor that detects that its CPU is going to melt, and it tries to shutdown the system, does this count as pain? In the same way, perhaps an insects nervous system is so simple that it feeling pain is not much different than that.

      • The line is based on intent. If you are ripping cockroach legs off just to watch it suffer, or if you are punching holes in a tree just to watch it die then it's cruel. If you are doing honest research and experimentation then it may not be cruel. It still may not be the right thing to do though.

    • Since insects don't feel pain, I think the anesthesia is more about the convenience of having the bug hold still while its leg is amputated. And maybe to make people feel better. Judging by your response, It worked.

      • Actually, we're unsure whether or not insects feel pain. Many possess opioid/opiate receptors, which would suggest that their body may produce opioids/opiates to nullify pain. In which case, they may in fact feel pain, or else they'd have no reason to have those receptors. Given that, the safer assumption is to assume they do.
        • Sorry, no. The recent discovery of endogenous opioid peptides and their receptor sites in various invertebrates (including insects) may encourage the belief that these animals can experience pain in view of the analgesic role of opioid peptides in mammals. However, the various functions, unrelated to pain experience, which are mediated by opioids in mammals, as well as the known occurrence of two such compounds in a protozoan, suggest that the endogenous opioids of invertebrates may function in regulating
