The International Team of Neurologists at the University of Dublin, the University of Dublin, Ireland, found the brain integrates visual and auditory signals to make faster decisions. The work was published in Nature Human Behavior (NHB) magazine.
During the experiment, the participants watched animation with moving points and at the same time heard a number of votes. They had to press the button when the points, voices or both changed. Electroencephalography (EEG) records that the image and sound are changing, visual and auditory decision-making processes take place in parallel, but their results coincide in the driving system, which accelerates reaction.
Modeling has shown that hearing and visual "storage" of information works separately, but before transferring the signal to the brain movement, they combine data for a common standard for operation. This integrated version best explains the results, especially when researchers have deliberately delayed in one of the waves.
The authors note that the obtained model describes the architecture of the brain, through which the multinational decisions pass, and can help develop diagnostic and therapeutic methods of perception disorders.
