Dual logic and cerebral coordinates for reciprocal interaction in eye contact.

Lee RF - PLoS ONE (2015)

Bottom Line: 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.

ABSTRACT
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.

A block diagram describes the exogenous-endogenous dual systems and their stimuli-responses model.The exteroceptive stimulus σ consists of p and q states for “seeing eyes only” and “seeing face without eyes”. The arising interoceptive stimuli π and θ are the dual pairs of p and q. The BOLD response Ω consists of exogenous response Ω+ and endogenous response Ω-. The exogenous Ω+ can be further decomposed to two states x and y for “reciprocal responses and non-reciprocal responses; the endogenous Ω- can also decomposed to two states ξ and ψ which are the dual pairs of x and y.

Mentions: Within the dual logic framework, a brain in the dfMRI experiments in Fig 1 can be formulated by a stimulus-response model shown in Fig 2, in which every stimulus and response are decomposed into two states for the purpose of distinguishing reciprocity and non-reciprocity.
