Today, microbiology specialists from the University of Sydney presented the results of their new research on how pain can serve as a neural node for triggering hypersensitivity in animals – in particular, the focus of their new research was on studying these properties in flower flies. Experts sought to prove their previously laid out theory that the symptom of chronic and acute pain, typically experienced by a person in various situations and injuries, may also be characteristic of insects – which was partly proven in their current study regarding chronic pain in flies.
Flower flies were chosen by experts for good reason – the fact is that in comparison with many other insects, they have a fairly simple genetic structure and can be easily changed by external genetic tools. What was done – the specialists processed the neural map of several flies with a special substance that “illuminates” the neurons and nodes during their activity.
Then they deliberately damaged one of the paws of the flies and left it to heal – while observing this, they registered a sufficiently strong neural surge in the region of the ventral cortex, which in some way related to flies and people in this situation, because we have pain is also observed activity in this part of the brain. Moreover, experts found that after damage to one of the fly's paws, the other legs also became more sensitive to potential damage, which to some extent changed the behavior of the fly itself. And this indicates that the neural nodes and responses in flower flies can be really more complex than expected.
All this together indicates that most likely it is about the possibility of using this knowledge in order to compile better and more effective treatment options for various acute pain syndromes in people – it is quite possible that the results and conclusions drawn may be decisive in creating conceptually new drugs. and medical treatments. However, it remains only to wait for the final completion of the experiment.
