New Study Shows Insect Feels Pain Like Human Beings

It has been a common belief that insects are instinctive, mindless creatures with robotic-like reactions to the world and all its impulses but the new Study has shown that this belief is wrong. The new Study has shown the complex behaviors, from bees communicating through dance to incredible feats of ant cooperation and now we have mounting evidence that these little creatures that run our world may also experience pain. Animals respond in a range of physiological and behavioural ways to unpleasant stimuli, such as chemical burning, sharp cutting, and bruising pressure, which is detected by the sensory nerve system. The perception of pain is one of these. It is generally known that insects respond by avoiding possibly harmful touch.

After having its leg removed, the frequently studied fruit fly, Drosophila, exhibited signs of persistent discomfort, according to several investigations. Researchers discovered that the fruit fly’s contralateral limb developed hypersensitivity after it had fully recovered. According to the authors, this was caused by the fly’s nerve chord losing its “pain brake” function. A pain brake mechanism reduces the experience of pain, but in fruit flies, it was completely eliminated when the sensory nerves were overstimulated. However, since even bacteria will flee from unpleasant stimuli, it is not as easy to spot pain in other species as it is to look for a negative response to a damaging interaction.

New Study Shows Insect Feels Pain Like Human BeingsWe need a sophisticated physiological system with connections to our brain and potentially even emotions in order to consciously detect a sense of pain. Pain receptors called nociceptors alert our brains to harmful stimuli in mammals, where neurons produce the unpleasant, subjective, physical, and emotional sensation of pain. Studies have revealed that nociception and pain may be controlled separately from one another and have found different regulatory mechanisms for each. In insects, these mechanisms have not yet been thoroughly characterised.

The ability of nerve impulses from the brain to modify pain perception is one characteristic of human pain perception, according to Matilda Gibbons, a neurobiologist at Queen Mary University. “Due to the body’s opiates’ ability to block the nociceptive signal, soldiers may occasionally be unaware of critical injuries while on the battlefield. Thus, rather than focusing only on fundamental nociception, we sought to determine if the insect brain had the neuronal processes that would render the experience of a pain-like sense possible.”
