Накратко на български

Връзката между мозъците на говорещия и слушателя се анализира чрез едновременни записи, за да се разбере как се постига взаимно разбирателство. Това помага да се разберат механизмите на ефективната комуникация, която е важна за образованието и медицината.

Brain to Brain Synchronization and the role of the shared semantics

We spend our lives conversing with one other. The effectiveness of verbal communication has important social, economic, and educational consequences. It is essential to many important activities, including student–teacher and patient–clinician interactions. The two main constitutive parts of verbal communication are speech production and speech perception. Typically, they have been studied separately and with isolated individuals. Nevertheless, a speaker producing perfectly intelligible speech and a listener being able to decode it, are necessary but not sufficient elements for successful communication. We have all experienced failed conversations in which no clear understanding could be drawn from the information conveyed. Recently, some scholars have applied a ‘two-person neuroscience’ (2PN) framework to investigate the specific neural mechanisms underpinning speaker–listener interactions. This framework involves collecting simultaneous neural recordings from more than one person, a technique referred as hyperscanning. The results have revealed that effective verbal communication is associated with a pattern of inter-brain coupling. In other words, the brains of people having an effective conversation are literally ‘on the same wavelength.’ However, the role played by the inter-brain coupling of oscillatory activity, for the two persons to understand each other is still unknown. We propose a research agenda that aims at discovering the interplay between different aspects of verbal interaction and brain-to-brain coupling.

Цел на проекта

A successful verbal communication demands mutual attentiveness and intelligibility of speech. Nevertheless, to transmit certain meaning, alignment between interlocutors according to their concepts and representations is also necessary. Recently, it has been shown (by the applicant and others) that a successful linguistic interaction is related to interbrain coupling. However, the role played by the inter-brain synchronization of oscillatory activity, for the two persons to understand each other is still not known. We propose a research agenda that aims at discovering the interplay between semantics and brain-to-brain synchronization. We will use coupled participants to analyze the inter-brain synchronization patterns underlying successful and disrupted verbal communication. Specifically, we will study two persons engaged in a seemingly natural linguistic, communicative scenario while simultaneously recording EEG brain activity. Using two different types of transcranial electric stimulation, we will study the contributions of a shared meaning to the inter-brain synchronization. In the proposed research, we will use TMS to disrupt semantic-specific brain regions to determine how experimentally-impaired communication modulates interbrain synchronization. Also, we will use tACS to manipulate neural coupling between participants trying to modulate mutual comprehension. Our study will thus provide important and novel evidence for the underlying interbrain patterns during effective communication and concerning whether interbrain phase coupling and mutual understanding are jointly modulated (linked). Results here would be opening the door to the quantification of linguistic interactions. In turn, they might suggest new methods for enhancing verbal communication in populations with meaning transmission deficits. Also has the potential to enable the implementation of methods and devices with the intended purpose of measurement and intervention over the interbrain coupling.
