“Mathematical” genes in fish could help fight neurodegenerative diseases

An international team of researchers recently studied the genes of fish in order to understand how our brain processes a math problem. This seemingly innocuous study take a big step towards understanding and processing the human brain. They have in particular reviewed hundreds of articles that explain how fish perceive quantities.

These latter seem use part of the brain which is similar to the area responsible for calculus in mammals and birds. Research is still in progress for find specific brain circuits which make the processing of numbers possible.

However, the results of this study could already help develop treatments versus some diseases of the human brain.

Many experiments have studied the sense of quantity in fish.

Numerous studies have already revealed the fish capacityin the same way as mammals or birds, counting objects. In effect, quantity estimate is essential to the survival of a fish. This is why hundreds of Pisces swim together to better escape marine predators.

These experiences have shown in particular that the behaviour of fish is similar to that of mammals or birds. They are able to tell the difference between large and small quantities. Other, even more extensive studies have allowed scientists to understand how much their counting strategies are similar to those of other species.

Discovery of the gene responsible for the sense of quantity advances medicine

the Professor Giorgio Vallortigarafrom the University of Trento, in Italy, declared that the zebrafish seems to be among the most efficient in this exercise. They then decided to focus on genes responsible for the formation of specific neurons normal quantities and discrete quantities.

The discovery of these geness responsible for quantity sense in fish could have important implications for the supported diseases affecting number cognition. Indeed, these neurodevelopmental diseases such as developmental dyscalculia affect many children around the world.
