This Is the First Time Scientists Have Seen Decisionmaking in a Brain

Neurologists from around Worked parallel to the world map, for the first time, they were the activities of the rat’s entire brain when they decide. At the same time, this achievement is associated with the use of serted electrodes inside the brain to record more than half million neurons distributed across 95 percent of the rat’s volume.

Thanks to the image obtained, researchers have already been able to ensure a theoretical architecture of thought: that is not a single region for decision -making, and instead it is an integrated process of multiple brain fields.

In order to illuminate all the regions involved in the decision -making process, the team trains a small steering wheel to remove circles on a screen to a small steering wheel. If the size was rightly moved towards the center, the animal had received sugar water as a reward.

After running this test with 139 rats across 12 labs and observing their brain activity, the test was able to map 620,000 neurons located in the 279 brain area, then a subset of 75,000 uninterrupted neurons was analyzed. The resolution of the neural map produced is unprecedented in the study of the brain and its neural networks during the thinking process. Furthermore, it presents a milestone in case of the monitoring sample type and the covered quantity of the brain field. Until now, only fruit flies, fish larvae or more complex brains were mapped.

The decision -making is an overall process

The results were published Two Papers In the journal nature. Although the scientists involved have acknowledged that data is not specific, they represent an inaugural point in the neural study of the decision -making. The value of this data is the fact that the neurological path to the decision -making is now more clear, which will allow scientists to better understand the skills of complex thinking and perform more advanced analyzes. Also, the dataset is publicly available.

“These initial decisions correct the aspects of the brain’s activity that was already available in a more limited study. Science Media Center tells SpainThe (Larma was not involved in research.) In short, information shows that in decision making, for example, many brain fields are involved, more than expected, when the regions are more distinct in sensitive processing. “

The adult has about 86 billion neurons in the human brain, capable of establishing thousands of synaptic connections with each other cell. Although its weight is about 1.4 kilograms, the human brain consumes about 20 percent of the total energy in the body, a significant high ratio for its size. Although today’s super computers exceed the brain in numerical calculations, none still matches the ability to learn, or adapt, and parallel processing. Neuroscience can still go a long way before the human decision -making nerve processes can be fully map, but the study like this takes us one step closer.
