Scientists find 'food neurons' in the brain

Scientists find 'food neurons' in the brain When we observe a cake, a watermelon or a fried chook, in our brain, in its temporal cortex, a certain organization of neurons is activated. Its exact location changed into decided by using scientists at the Massachusetts Institute of Technology (USA).Russian News

According to the journal Current Biology, over the past 30 years, exclusive companies of researchers have determined organizations of neurons inside the brain that “switch on” when a person recognizes a familiar face, frame, phrase or location. Now brain cells had been discovered that "recognize" food. The researchers arrived at this by means of processing the mind responses of eight people in extra than 10,000 pics. The brains of the subjects had been studied using useful MRI, paying attention to the paintings of the so-known as ventral visible pathway, which connects neurons inside the visible zone with the temporal lobe of the brain liable for item popularity.Covid

Thanks to progressed system, which now allows you to take pix with better spatial decision, scientists had been capable of see what became previously hidden from them. They advanced an algorithm that lets in them to distinguish between the reactions of person neuronal populations in every voxel (a section of brain tissue similar to a 1x1x1 mm cube). And this is notwithstanding the truth that in every such voxel, scientists see loads of thousands of different neurons! First, the researchers showed that 4 recognized groups of neurons could be diagnosed with this technique. Then a 5th institution turned into observed, which became more lively while someone become proven images of food. Jobs

   In the route of the look at, it grew to become out that in some participants within the experiment, the "fit to be eaten" organization of neurons is notably selective when it comes to photos that depict cooked dishes, and no longer raw meals from which they are prepared. 

The authors of the work notice that the next step of their paintings might be the have a look at of comparable brain reactions in early youth. It will also be interesting to apprehend whether or not there is a similar gadget for recognizing sorts of food in animals.

- This article is an instance of how new expertise is generated based on Big Data gathered in Internet databases. I would not honestly call this a "step forward" in cognitive technology, as many people interpret it. The look at below dialogue is based at the database of results of fMRI scanning of the brain in numerous states and upon presentation of stimuli of diverse nature, created within the United States, unheard of in phrases of the amount of information. The advantage of the author of the paintings Nancy Kanwisher and her co-authors is the development of mathematical algorithms for the evaluation of MRI indicators. Using the affected person corporations already included within the database, they “tricked out” the usage of mathematical strategies to attain the most exact image of the distribution of hobby in volumetric cortical zones thus far. Mathematically, it seems like large matrices of sign intensity distribution,
