Which part of our brain responsible for inventing stories?

Despite the relatively good information about the work of the Central nervous system and availability of knowledge about many physiological processes, the data about how and where exactly is the formation of certain functions are still unclear. But now, thanks to the efforts of neuroscientists at McMaster University (Canada), one “white spot” in our Central nervous system has become smaller thanks to the identification of brain areas that are responsible for inventing stories.

A very curious study says the Journal of Cognitive Neuroscience. For the experiment, researchers chose 21 people (17 women and 4 men) who were fond of painting and fine art. In the course of the experiment, the subjects performed magnetic resonance imaging (MRI). The experiment was divided into 2 parts: narrative and descriptive. In the first case, people were given a plot consisting of 1-2 sentences, and then based on these data, they had to invent the further development of the story in three different forms: in the form of a monologue, through gestures and with the help of drawings. The second part was the fact that subjects needed to do all the same steps as above, but this should have been done not with the beginning of the story, and with any inanimate object, provided, however, that in this case the stories of the characters-people should not be.

Eventually managed to establish that in inventing stories, regardless of the form of the narrative, the greatest role is played by the temporo-parietal site (TPJ), responsible for the collection of information from the thalamus, limbic, visual and auditory systems, as well as for its processing, the superior temporal sulcus (STS), which analyzes it, recognizes faces and is involved in social perception and posterior cingulate cortex (PCC), responsible for memory and learning. As the authors of the study, the findings will help to better understand the functioning of the CNS and to improve the diagnosis and treatment of psychiatric disorders and diseases associated with impaired memory and perception.
