New research helps explain how social understanding is performed by the brain
An important question has been answered about how social understanding is performed in the brain. The findings may help us to attain a better understanding of why people with autism and schizophrenia have difficulties with social interaction. Using magnetic stimulation to temporarily disrupt normal processing of the areas of the human brain involved in the production of actions of human participants, it is demonstrated that these areas are also involved in the understanding of actions. The study is the first to demonstrate a clear causal effect, whereas earlier studies primarily have looked at correlations, which are difficult to interpret.
In a study to be published in Psychological Science, researchers from Aarhus University and the University of Copenhagen demonstrate that brain cells in what is called the mirror system help people make sense of the actions they see other people perform in everyday life.
Using magnetic stimulation to temporarily disrupt normal processing of the areas of the human brain involved in the production of actions of human participants, it is demonstrated that these areas are also involved in the understanding of actions. The study is the first to demonstrate a clear causal effect, whereas earlier studies primarily have looked at correlations, which are difficult to interpret.
One of the researchers, John Michael, explains the process: "There has been a great deal of hype about the mirror system, and now we have performed an experiment that finally provides clear and straightforward evidence that the mirror system serves to help people make sense of others' actions," says John Michael.
Understanding autism and schizophrenia
The study shows that there are areas of the brain that are involved in the production of actions. And the researchers found evidence that these areas contribute to understanding others' actions. This means that the same areas are involved in producing actions and understanding others' actions. This helps us in everyday life, but it also holds great potential when trying to understand why people with autism and schizophrenia have difficulties with social interaction.
"Attaining knowledge of the processes underlying social understanding in people in general is an important part of the process of attaining knowledge of the underlying causes of the difficulties that some people diagnosed with autism and schizophrenia experience in sustaining social understanding. But it is important to emphasize that this is just one piece of the puzzle."
"The findings may be interesting to therapists and psychiatrists who work with patients with schizophrenia or autism, or even to educational researchers," adds John Michael.
Facts about the empirical basis
The participants (20 adults) came to the lab three times. They were given brain scans on the first visit. On the second and third, they received stimulation to their motor system and then performed a typical psychological task in which they watched brief videos of actors pantomiming actions (about 250 videos each time). After each video they had to choose a picture of an object that matched the pantomimed video. For example, a hammer was the correct answer for the video of an actor pretending to hammer.
This task was intended to gauge their understanding of the observed actions. The researchers found that the stimulation interfered with their performance of this task.
Innovative method
The researchers used an innovative technique for magnetically stimulating highly specific brain areas in order to temporarily disrupt normal processing in those areas. The reason for using this technique (called continuous theta-burst stimulation) in general is that it makes it possible to determine which brain areas perform which functions. For example, if you stimulate (and thus temporarily impair) area A, and the participants subsequently have difficulty with some specific task (task T), then you can infer that area A usually performs task T. The effect goes away after 20 minutes, so this is a harmless and widely applicable way to identify which tasks are performed by which areas.
With continuous theta-burst stimulation, you can actually determine that the activation of A contributes as a cause to people performing T. This method thus promises to be of great use to neuroscientists in the coming years.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
