This is the first time that scientists have seen decision -making in the brain

Neuroscientists from all over The world has worked in parallel with the map, for the first time, the entire brain activity of mice while making decisions. This achievement involves the use of electrical electric poles inserted into the brain to record the activity of more than half a million nerve cells distributed over 95 percent of the volume of rodent brain.

Thanks to the image obtained, the researchers were able to confirm an already theoretical intellectual structure: that there is no single area responsible exclusively for making decisions and instead, it is a coordinated process between multiple brain areas.

To shed light on all the areas involved in this decision -making process, the team trained mice to convert a small driving wheel to transport circles on the screen. If the shape moves properly towards the center, the animal receives sugar water as a reward.

After running this experiment with 139 mice across 12 laboratories and monitoring brain activity, the experiment was able to assign 620,000 neurons located in 279 strokes, with a branch of 75,000 nerve cells well known and then analyzed. The decision of the productive nerve map is unprecedented in studying the brain and nerve networks during the thinking process. Moreover, it represents a milestone in terms of the type of sample and the extent of the covered brain area. To date, complete brains of fruit flies, fish larvae, or small sections of the most complex minds have been set.

Making decisions a comprehensive process

The results were published in two papers In the Journal of Nature. Although the scientists concerned admit that the data is not final, it represents a starting point in the nervous study of decision -making. The value of this data is the fact that the nervous path to make decisions has become more clear, which will allow scientists better understanding the complex capabilities of thinking and making more advanced analyzes. In addition, the data set is available to the public.

“These initial conclusions confirm the aspects of brain functions that were already suitable from the most limited studies available. It seems as if we were suspected of how the movie ended without the end of the end; they have shown us now,” Juan Lerma, a researcher in the Spanish National Research Council, Tell the Scientific Information Center Spain. (Lerma did not participate in the research. “In short, the data shows that in decision -making, for example, many brain regions participate more than expected, while in sensory treatment, the areas are more distinctive.”

An adult human brain contains about 86 billion nerve cells, each of which is able to create thousands of interlocking connections with other cells. Although it weighs about 1.4 kilograms, the human brain consumes about 20 percent of the total body energy in comfort, which is significantly high in size. Although supercomputers today outperform the brain in numerical calculations, none of them match the efficiency of energy or its ability to learn, adapt and parallel treatment. There is still a long way before neuroscience can set nervous processes to completely make human decisions, but studies like this take us one step.
