study published in the International Journal of Neuroscience (The Journal of Neuroscience), for the first time shows the effect that genes have on our brain wiring, but also sheds light on the structure of the brain.According to the lead author, Dr. Alex Fornito of Neuropsychiatric Center at the University of Melbourne, the results of the study will help to understand why some people find it easier to perform certain tasks, as well as the genetic causes of mental disorders and some neurological diseases.
Fornito According to the organization structure of the brain remained a mystery to scientists for many years."The brain - an unusually complex network of billions of nerve cells connected in trillions of fibers," - he says.
«The brain tries to maximize its effectiveness, adhering to the golden mean between the creation of more links to ensure efficient communication and minimizing the" value "or the number of entries required to build these ties.Our results indicate that this golden mean, in other word
«Ultimately, this research can help to find out which genes are most important when considering the differences in cognitive abilities, risk of psychiatric disorders and neurological diseases such as schizophrenia and Alzheimer's disease, as well as help develop new methods of gene therapy for the treatment ofsuch violations. "
«Despite the fact that genes play a major role in brain function, the environment and other factors also contribute to the development of any mental disorder, and other brain disorders," - he says.The research team, which included scientists from the University of Queensland and Cambridge in the UK, compared the brain scans of 38 images of identical and 26 fraternal twins from the Australian Twin Registry.
Using the latest technology, the researchers were able to construct a detailed scheme of brain structure of each participant and to measure the effectiveness of communications throughout the brain, including the specific parts of the brain."We found that people are very different in terms of the functioning of the brain, and that more than half of these differences are due to genes," - says Dr. Fornito.
More than half (60%), differences in the brain caused by genes of different people.The strongest of these differences manifest themselves in the prefrontal cortex, which plays a vital role in the planning, strategic thinking, decision-making and memory.
Preliminary studies have shown that people with more efficient brain wiring performed better in the intelligence test and that the efficiency of the brain is reduced in people with schizophrenia, particularly in the prefrontal cortex."Our discovery opens up a whole new area of research for scientists all over the world" - says Fornito.
