Does the fly brain work like a human brain?

Surprisingly, each species's brain is different, but in some cases they work the same. This finding reveals many interesting things about the evolution of the brain, contributing to explaining the mechanism of mental disorders.

Scientists at the Imperial College of London and the University of Arizona found that some of the arthropod's activities (like flies and crabs) are very similar to vertebrates (such as fish, mouse .) including humans.

Studies show that areas in the center of the brain stem from embryonic stem cells. Although there are significant differences between species, these areas develop and operate in the same way, especially in controlling genetic programs.

It's unbelievable, but 3 brains (left to right, flies, mice and humans) have amazing similarities in behavioral regulation.

Neuroblast of humans and insects work on the same program and regulate identical adaptive behaviors of both internal stimulation (such as hunger, sleepiness) and external stimuli such as light. , darkness, temperature .

That similarity stems from an evolutionary virgin. That means that the 'prototype' of modern brain diagrams appeared very early, before there was a division into species. Moreover, the basic principles of the brain do not change during the hundreds of millions of years of evolution. So the human brain can be studied through the brain model of low-level animals.

Because the structure of the central part of the vertebrate and arthropod's brain is similar, scientists can perform complex neurobiological experiments on simple animals.

For example, it is understandable why the basal ganglia can lead to serious mental health problems, from autism, schizophrenia, psychological disturbances to degenerative diseases. Neurological chemical such as Parkinson's disease and dementia. Problems at the complex in the center of the fruit fly's brain also have similar consequences.
