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