Scientists have discovered the brain areas responsible for the compilation of stories

Ученые обнаружили участки мозга, которые отвечают за составление рассказов

Scientists determined what brain areas are involved in the drawing and description stories.Neuroscientists at McMaster University (Canada) conducted an experiment with students, which showed what areas of the brain participate in the drafting of anthropocentric narratives. A study published in the journal of Cognitive Neuroscience, writes the with reference to the Telegraph.

Scientists wanted to understand why people are keen on plot-stories. To do this, they conducted a simple experiment. It was attended by 21 students, 17 of them girls. They are all fond of fine arts. During the experiment, participants were scanned using magnetic resonance imaging (MRI) and declared short titles, which contained the story – for example, “the Surgeon found a pair of scissors inside patient” or “Fisherman saved the boy from a frozen lake”. Then from the suggested phrases the students were full-fledged stories, which were expressed in three formats: in the form of a monologue, in the form of gestures and drawing on the tablet.

As a control, the researchers used a second task, similar to the first. In it, participants were offered a random item, like binoculars, they were described in the same way as the first time, but with one condition: the description should not be people. The first task the authors call “narrative” and the second “description”. So they wanted to isolate the reaction of the brain, which manifests itself solely in response to plot the history of that people.

By “subtracting” some of the reactions from other scientists have found that in writing and storytelling, regardless of the method of narration, a crucial role is played by three areas: the temporo-parietal site (TPJ), superior temporal sulcus (STS) and posterior cingulate cortex (PCC). The first is responsible for gathering information from the thalamus, limbic, visual, auditory, and somatosensory systems and processes. The second analyzes it, recognizes faces and is involved in social perception. The third function associated with learning and memory. This cluster they called “narrative center.”

In the future, the authors intend to understand the differences in brain reactions to the story in the first person and the passive contemplation of history.
