“…In the time of a generalized financial crisis such as those currently faced by several Western societies, often not all of the research structures could afford to buy two fMRI devices to study social interactions. However, one interesting attempt to obtain a relatively low cost fMRI hyperscanning facility has been performed by the group of Lee and coworkers (Lee et al, 2010, 2012). In fact, they have realized a novel MRI dual-head volume coil (DHVC) that allows for the acquisition of dyadic fMRI (dfMRI) signals from two subjects’ brains while the subjects are in close proximity of one another inside a single scanner.…”

This paper reviews the published literature on the hyperscanning methodologies using hemodynamic or neuro-electric modalities. In particular, we describe how different brain recording devices have been employed in different experimental paradigms to gain information about the subtle nature of human interactions. This review also included papers based on single-subject recordings in which a correlation was found between the activities of different (non-simultaneously recorded) participants in the experiment. The descriptions begin with the methodological issues related to the simultaneous measurements and the descriptions of the results generated by such approaches will follow. Finally, a discussion of the possible future uses of such new approaches to explore human social interactions will be presented.

In order to scientifically study the human brain’s response to face-to-face social interaction, the scientific method itself needs to be reconsidered so that both quantitative observation and symbolic reasoning can be adapted to the situation where the observer is also observed. In light of the recent development of dyadic fMRI which can directly observe dyadic brain interacting in one MRI scanner, this paper aims to establish a new form of logic, dual logic, which provides a theoretical platform for deductive reasoning in a complementary dual system with emergence mechanism. Applying the dual logic in the dfMRI experimental design and data analysis, the exogenous and endogenous dual systems in the BOLD responses can be identified; the non-reciprocal responses in the dual system can be suppressed; a cerebral coordinate for reciprocal interaction can be generated. Elucidated by dual logic deductions, the cerebral coordinate for reciprocal interaction suggests: the exogenous and endogenous systems consist of the empathy network and the mentalization network respectively; the default-mode network emerges from the resting state to activation in the endogenous system during reciprocal interaction; the cingulate plays an essential role in the emergence from the exogenous system to the endogenous system. Overall, the dual logic deductions are supported by the dfMRI experimental results and are consistent with current literature. Both the theoretical framework and experimental method set the stage to formally apply the scientific method in studying complex social interaction.

“…As an example from game studies, Kätsyri et al ( 2013 ) have demonstrated the substantial qualitative difference between playing and just watching, motivating the goal of deeper engagement in neuroimaging studies. Currently, methods are being developed for scanning synchronous brain activations of two people who are in direct interaction in magnetoencephalography (MEG) with one another via real-time video (Baess et al, 2012 ), as well as in direct bodily interaction in a two-person fMRI scanner (Lee et al, 2012 ). Future will show, how two-person neuroimaging will meet the challenges of making analytical inferences of a system consisting of two “black boxes” instead of one.…”

From naturalistic neuroscience to modeling radical embodiment with narrative enactive systems

Mainstream cognitive neuroscience has begun to accept the idea of embodied mind, which assumes that the human mind is fundamentally constituted by the dynamical interactions of the brain, body, and the environment. In today’s paradigm of naturalistic neurosciences, subjects are exposed to rich contexts, such as video sequences or entire films, under relatively controlled conditions, against which researchers can interpret changes in neural responses within a time window. However, from the point of view of radical embodied cognitive neuroscience, the increasing complexity alone will not suffice as the explanatory apparatus for dynamical embodiment and situatedness of the mind. We suggest that narrative enactive systems with dynamically adaptive content as stimuli, may serve better to account for the embodied mind engaged with the surrounding world. Among the ensuing challenges for neuroimaging studies is how to interpret brain data against broad temporal contexts of previous experiences that condition the unfolding experience of nowness. We propose means to tackle this issue, as well as ways to limit the exponentially growing combinatoria of narrative paths to a controllable number.
